What kind of lubricant to use for bicycle bearings

Liquid lubricants

Special oil bottles are versatile and are used to process many structures. Bicycle chain lubricant is indispensable when you need to machine a small, hard-to-reach part, or when there are many protruding corners in the part. The ease of use explains the ability to process parts with a syringe. Among the shortcomings, one can single out a small resistance to low temperatures. When grease is selected. Cheap and quality samples can be found in liquid configuration.

Liquid oils

Liquid lubricants include standard machine oil that can be used for bushings, brakes, and derailleurs. It is excellent for lubricating suspension forks. The main disadvantage is the quick washout of the oil with water. Therefore, this type of oil is not suitable for lubricating exposed parts such as chains or ropes.

When lubricating, it is important to try to remove excess from the surface of the bike, otherwise the adhering dust can quickly damage the moving parts. In addition, mineral oils will corrode rubber, so be careful not to spill liquid on tires.

Calcium grease

It has a yellow or green color, but the hue is definitely not bright. It is successfully used for metal surfaces. Calcium grease is virtually unreactive to moisture, so it is not necessary to re-lubricate the parts if exposed to rain or after washing your bike. Items that have been treated with calcium grease must be used at temperatures ranging from.30 to 50 degrees. It is not recommended to go beyond these limits.

Lithium grease

Possesses a red, sometimes yellow color. The parts treated with it must be protected from moisture, since the grease is washed off very quickly. Even light rain can cause the need to reprocess parts.

Such a lubricant is suitable for climatic zones with low temperatures, as it can withstand up to.50 degrees without changing its basic properties. The positive temperature can be any. Lithium bike grease can withstand up to 150 degrees. Any parts can be processed, excluding all items that contain aluminum.

How to lubricate bicycle bearings: which lubricant is better

  • 1 Why lubricate bearings?
  • 2 Types of lubricants
  • 3 Which one is better to choose?

Bicycles use a rolling bearing, which consists of outer and inner rings with raceways, balls (rolling elements) and a cage. an annular blank with holes for the balls. And the principle of operation lies in the movement due to the friction of the balls on the tracks on the rings.

When friction arises from movement, natural wear of parts occurs. bodies and raceways. The presence of lubricant increases their performance and wear resistance.

  • Bushings. The hub of the front and rear wheels contains several bearings and ensures the rotation of the wheel around its axis. This assembly is a lever and fulcrum; the better the rolling and sliding of the bearing in the hub, the easier the wheel turns. A decent quality and sufficient quantity of lubricant will also ensure energy conservation.
  • The carriage is one of the main propulsion units of the bicycle, which ensures the rotation of the connecting rods (the jumpers between the pedals and the carriage) and makes it easy to move. A well-oiled bottom bracket won’t be a problem, as the biggest loss of pedal energy can be due to it. A bicycle chain is put on the carriage.
  • The pedal is the fulcrum, the place where motor energy appears, where comfort and ease of driving depend on the quality of lubrication. The steering column is where the frame, handlebar and fork join. High-quality and lubricated headset bearing for comfortable ride.

Bearings come with protective covers that keep the insides from dirt and debris, and without covers. such designs are especially sensitive to external influences and dirt, require more thorough and voluminous lubrication, which will take dirt with it when it leaves the device.

Important! The processing time should be chosen based on the frequency and intensity of bike use. with daily use, lubrication should be carried out more often than with less frequent use. However, in both cases, it is recommended to carry out prophylaxis at least several times a season with the same frequency.

The work will take no more than half an hour, but there will be firm confidence in the safety and performance of the bike.

  • Conservation. to prevent corrosion of metals and mechanisms;
  • Anti-friction. to reduce wear and friction in bearings.

The classification includes several more items, but they are not related to bearings and are created for ropes and threaded systems.

The category of greases includes:

  • Calcium greases. ordinary grease, a hydrated grease thickened with calcium soap, which has a high viscosity and poor washout, so it is used more in the automotive industry. Calcium greases include CIATIM 221, a thickened heat-resistant grease, originally created for the treatment of bearings. Allows mechanisms to operate at ambient temperatures from.60 to 150C. Possesses waterproof properties, retains working properties when scalded and boiled.
  • Lithium greases are a type of grease thickened with lithium soap and stearic acid. It is a viscous gel emulsion with heat resistance, good adhesion to metals and non-corrosive.

CIATIM 203 is an earlier analogue of the above-mentioned grease and has a lower operating temperature. from.50 to 90C. It also has lower quality characteristics, however, for normal use of a bicycle, it does not make a difference and only affects the operation of serious equipment. airplanes, vehicles, etc.

Litol-24 is excellent for all types of bearings used in bicycles. Possesses high stability, water resistance, does not harden when heated. Working temperature from. 40 to 120C. Possesses anti-corrosion and conservation properties.

Graphite grease is a petroleum oil thickened with calcium soap with the addition of graphite. The effect is similar to solid oil, with the difference that graphite is present in a thick oil base.

Important! This compound is not suitable for use in bearings due to the presence of graphite, which tends to damage small elements. Used in tractors, tanks and other heavy low-speed devices.

Teflon grease is an excellent low slip antifriction material. Great for lubricating bicycle bearings in moderation.

Silicone grease has excellent waterproof and water-repellent properties, making it ideal for use in wheel bearings and carriages. Made by thickening silicone oil. Retains and does not degrade rubber, which helps it to be used in sealed bearings in contact with gaskets. Protects, but does not eliminate corrosion.

Aerosol lubricants are suitable for quick treatment here and now, when the result is needed in the next few minutes. This is an effective method, however, does not obviate the need to use other types of lubricants with a more thorough approach to the process, including additional disassembly, cleaning, washing and parts.

What is the best bicycle bearing grease

Types of bicycle lubricants

Graphite grease

Graphite grease is available in powder configuration. Typically used for connections involving threaded elements. It is the most durable bicycle lubricant, so it is used where there is no need to constantly disassemble and redo the mounts, as it can save time on the frequency of subsequent repairs. Care is required when working with graphite grease, as an inexperienced technician can get dirty very quickly.

How often to carry out the procedure?

The answer to this question is quite simple. it must be lubricated every season. This is especially important after winter if you have sent your bike for storage. It takes no more than a couple of hours to put the bike in order after hibernation.

Some cyclists give their bikes to mechanics, but it’s best to learn how to do this yourself so as not to get screwed up at the worst possible moment. But if you neglect lubrication altogether, then be prepared that one day the parts will begin to fail one after the other.

Seasonal lubrication includes all parts except the chain and fork. Chain lubrication is usually at the discretion of the owner, who can determine how often to lubricate the chain. Or you can just wait until the chain starts to squeak. But this does not mean that she has reached a critical point. Dry chain can withstand up to 30 km of driving.

And also there is an opinion that the gear cables should not be lubricated at all, otherwise dirt and dust will stick to them, making it difficult to move. However, many professional mechanics still do this, but use substances that repel foreign objects.

In general, it is worth noting that most of the small parts must be lubricated so that they do not sour. This is common for items such as seatposts, pedal threads, stem bolts and others. Unscrewing sour parts can be very problematic.

Bicycle bearing grease which is better

Bicycle bearing grease. How to choose?

Bearing lubrication is an indispensable part of bike care, because for the iron horse to function properly, all moving or rubbing parts must be lubricated on a permanent basis.

Since there are certain types of lubricants, you need to read the information about the selected lubricant before buying.

Technical Vaseline

  • possible damage to the chrome-plated layer of the bearings;
  • poor cleaning of the petroleum jelly itself (when compared with medical);
  • lasts a long time and is applied to any parts of the bike;
  • there is no transparency; color is brown or yellowish;
  • provides good protection against air, rust and water.

Bicycle Bearing Fluids

They are produced in various types of containers: small cans, barrels, as well as oil bottles. The degree of viscosity varies. Car oil is used to lubricate, for example, ratchet ball bearings or brake levers. You can handle bike bushings. Three drops are enough to refresh the product.

It is advised to accurately observe the dosage in order to avoid leakage of excess, which can destroy the rubber tires. The spindle oil has a lower viscosity. It is poured into the fork of the bike, and its legs are also coated. Refill fluid lubricant every 2-3 weeks or immediately after driving in rainy weather.

Penetrating oils

This type of dissolving material is represented by WD-40 grease. Produced in a container aerosol. Corrodes old grease layer and excellently liquefies corrosion. Good water repellent. There are analogues of the domestic manufacturer: UNISMA and Any Way. All of these fluids are solvents, not lubricants.!

The main task of the WD-40 and its analogues is precisely to get rid of the old layer of grease and corrosion, and not to lubricate the bike. But Nanoprotech, also a penetrating oil, can serve as a lubricant. but it can only be lubricated with rubbing parts that are not under high pressure.

Electric motor bearings

Bearing grease for electric motors keeps them clean and prevents dust, sand or dirt inside the part.

The appropriate oil is used for each type of engine. It should be changed periodically.

Any system needs periodic oil top-up. This should be done every 10 days. Also, high temperature bearing grease needs to be completely replaced every 3 weeks with constant use of the equipment.

Pigment lubricants

One of the first to use pigment substances in the operation of equipment when high temperatures are reached.

One of the most famous is the blue grease for bearings VNIINP-246 (GOST 18852-73). It looks like a rather mild ointment. Its feature is a large limit of operating temperatures: from.80 to 200 degrees.

Blue grease for bearings is used for lightly loaded high-speed rolling parts, in electric motors, gear mechanisms operating under conditions of wide temperature run or vacuum.

However, this is an expensive product. There are other, cheaper options for similar substances. In the same temperature range, VNIINP-235 dark purple ointment is used. But it is not suitable for a complete vacuum. This product is used in low-speed rolling bearings, aircraft control systems.

Temperature regime

At low temperatures, high temperature bearing grease crystallizes and thickens. The substance not designed for operation at high heat will coke, dry out.

Therefore, when using a means for a motor, for example, an electric motor, it is necessary to use paste-like means. They will ensure the normal operation of the system at temperatures from 200 to 1000 degrees. Until this indicator rises to the 280-degree line, high-temperature paste-type lubricants act as an anti-seize coating. This protects the part from jamming.

For a part to work in the.30 to 120 degree range, the best bearing grease will be mineral based.

At temperatures from.40 to.70 degrees, silicone agents should be used to slide the elements of the parts. In everyday life, they are used less often than the two previous options.

Temperature is not the only factor to consider when choosing a sliding vehicle. Which one is better to choose will tell you the speed of the part, the type of medium and the loads acting on the system.

Lithium greases

Special greases for bearings are their lithium varieties. They are highly water-repellent.

Lithium bearing grease has one of the widest operating temperature ranges. This is why it is known as the most versatile gliding aid.

The product is prepared with synthetic materials or their mixtures with mineral oils. Various organic and inorganic substances are used as a thickener.

With an increase in the speed of rotation of parts, the viscosity of the substance decreases.

The most famous lubricants of the presented type include CIATIM-201, 202, OKB 122-7. For closed bearings, CIATIM-203, VNIINP-242 are used.

Complex calcium, sodium lubricants

Of the heat-resistant agents, complex calcium greases are the most common varieties, since they have a relatively low cost.

There are two types of them. The first type is uniol, obtained by thickening oil oils with synthetic fatty acid kSa soap. The second is CIATIM-221. It is obtained by thickening polysilixane liquids with kCa-soap.

The first group includes such substances as “Uniol-ZM”, “Uniol-1”, “Uniol-2”.

VNIINP-207, 214, 219, 220 belong to the second type of complex calcium lubricants. They contain up to 3% molybdenum disulfide.

Of the sodium thermostatic lubricants, only the production of NK-50 has survived. It was created even before World War II.

Rotation, loads and bearing environment

When the speed limit for which the grease is designed is reached, it will spread to the edges. Inside, the part begins to dry out.

The limiting speed is set individually for a medium such as bearing grease. Which one is better should be determined based on this indicator. Synthetic means are used for high-speed mechanisms.

Negative factors affecting the sliding substance should be considered when choosing the best bearing grease. Water, dust, acid or steam affect it.

For maintenance of equipment used in conditions of the influence of acids, solvents, preference should be given to means that are resistant to such influences.

For example, a bicycle bearing grease must be resistant to a lot of moisture and dust.

The load is also taken into account when choosing a component care product. The higher it is, the more the substance is squeezed out of the contact area. Containing solids (graphite, molybdenum), the lubricant will ensure reliable operation of the system. There are even completely dry sliders.

Bike bearings

You shouldn’t skimp on products for systems. The quality of this material directly affects the operation of the equipment.

The frequency of servicing the bearings of a bicycle depends on the type of assembly. Bushings on sealed cartridges are serviced much less frequently than on open cartridges.

Bulk-type bicycle bearing grease must be changed at least once a season or twice a year.

The best for this is a hygroscopic type of product with a large temperature range and good adhesion, transparent type.

Bearing lubrication functions

The lubricant is used for a specific purpose. The main functions of a substance can be called the following:

  • reduction of friction between the constituent parts of the part;
  • an increase in the sliding of surfaces as a result of their deformations when a load occurs;
  • forming an interlayer, the bearing grease reduces the impact of parts of the part during operation, extending their durability;
  • allows you to evenly distribute the heat generated by friction of the constituent elements against each other;
  • performs the function of a coolant at elevated operating temperatures;
  • corrosion protection;
  • prevents the ingress of dust, dirt from the outside into the part.
