Lubricants for bearings provide long-term operation and increase the speed and smoothness of the rotation of friction elements. They have different consistency and temperature regimes of use. Some are designed for strong negative indicators of the thermometer, and for work in hot conditions. Others can function only in the average temperature range. They differ in their anti-friction properties and the ability to provide the equipment with a certain load weight. If you lubricate the bushing of a car or high-speed machine with an unsuitable composition, this will lead to premature deterioration of the workers. Lubricating a bicycle or bearings of motors from weakly powerful aggregates with expensive mixtures, one can not feel their quality and overpay. Reading this article gives a clear idea of the antifriction properties of lubricants and teaches you to distinguish between whichever composition is better to use.

Best common bearing greases
These blends are designed for friction units of bicycles, mopeds or electric motors with low revolutions. They can be pushed into machine tools in production or used in spinning devices in private workshops. They are also good in agricultural machinery. The substances in their composition are designed for low temperatures and stress. Here are the best general purpose greases by user version.
BP Energrease LS-EP 2 - for
machines This product from British Petroleum is based on highly purified oils with oxidation inhibitors and antifriction components. Universal lubrication can be used everywhere, but it is best suited for machines of any purpose( turning, milling), as well as conveyor mechanisms. Manufacturers recommend it to all equipment of textile, woodworking, paper and plastic products.
The lubricant is well pumped and shows shear stability or vibration on bearings. The product has a good viscosity, and its disintegration into oil and additives begins only after 18 hours of continuous operation at a temperature of 40 degrees. But the dropping begins already at the mark of the thermometer of 195 degrees, therefore the maximum temperature limit for lubrication is 140.
Advantages:
- the versatility of the facility;
- is easily pumped;
- does not fall out during shifts;
- is resistant to decay.
Disadvantages:
- small temperature range;
- the minimum volume of packaging is 15 kg.
Luqui Moly LM 50 - the best for
hubs German developers have created a grease based on a lithium complex with good anti-seize properties. This product is applicable in various systems, including central distribution, but it is best used to lubricate the hubs. The composition is resistant to water, which is relevant for the wheels. The product does not quickly become soft and remains permanently in the bearing.
Anticorrosive properties protect metal on the rotating elements of the hubs. The range of temperatures varies from -30 to +160, which is well suited for wheels. The tool contributes to a high load on the rotating parts with minimal wear and tear from friction and pressure. This German grease retains all its properties for a long time, when other similar substances age. Disintegration into oil occurs after 18 hours of operation. The viscosity corresponds to DIN 51562.
Advantages:
- thick;
- reliably protects against corrosion;
- does not leak out of bearings;
- repels water;The
- is suitable for operation under high load conditions.
Disadvantages:
- not very large temperature range;
- is very expensive.
Castrol LMX Li-Komplexfett - good for
tool The lubricant has a plastic helium structure that allows it to be quickly pushed into the bearing. Manufacturers used thickeners of the lithium complex in combination with a base consisting of mineral oil. Additionally, several additives have been introduced, whose proportions are strictly balanced. This gave an excellent product for the power tool bearings: bolgars, cutting machines, perforators.
The mechanical stability of the lubricant allows you to work with tools all day long. Even when the metal is heated, the lubricant does not flow out. The tool is designed to maintain work at high speeds. Resistance to solidification increases useful life. Lubricant has a high adhesion to the metal components, so it is not washed out or shaken out.
Advantages:
- eco-friendly formulation;
- is applicable for both machinery and tools;
- reasonable price;
- supports bearing operation at high speeds.
Disadvantages:
- bright color.
Best bearing lubricants for special loads
These lubricants have a lower kinematic viscosity, which allows them to better penetrate between the rubbing elements, maintaining slip and preventing wear. Manufacturers add to their composition special additives that increase their quality. This has found its application in construction machinery and equipment, as well as in racing vehicles.
Mobil Mobilgrease Special - for construction equipment
This American product is designed for use in bearings subject to constant vibration. Often, such loads are tested excavators and crane installations at the construction site or mining equipment. In its composition, developers used molybdenum disulphide, so that wear of parts becomes minimal. To prevent the mixture from flowing out of the rotating assemblies, lithium hydroxystearate was used. The thick consistency allows the tool to be held securely inside the bearing.
Due to the well-thought-out composition, the product protects metal elements well against corrosion, as well as wear during translational or oscillatory movements. Optimal application is the bearings and hubs at the chassis of the trucks. But this lubricant will flow out if the temperature of the metal rises above 130 degrees. Therefore, regular monitoring and refueling are required.
Pluses:
- well protects against corrosion if moisture gets into the unit;
- thickener based on lithium;
- is designed for vibration and vibration;
- consistency is convenient for pumping.
Disadvantages:
- low temperature range( from -20 to +130);
- fast flow rate;
- price.
Fuchs Titan Renolit Duraplex EP2 - for high temperatures
This lubricant combines selected oils and thickeners based on lithium soap. The developers have introduced into it an additional package of additives, which gives the mixture stability and stability at extreme temperatures, due to the high speed and strong friction of the weight of the structure, rotating on the bearings. Such lubrication is best suited for blowers with hot air and electric motors from large industrial machines.
Good in it and anti-corrosion properties. Water resistance does not allow washing the grease when cleaning the equipment with water jet under pressure. The mixture has good colloidal stability at a temperature of 80 degrees for 18 hours. Usually it can be used in the range of -30 to +160.At short-term excesses of up to 200 degrees, nothing happens, since the dropping of the substance starts from 250. The packaging can be 400 and 500 grams, or 25 and 180 kg for bulk purchases by large enterprises.
Advantages:
- additional additive package;
- work at temperatures up to 200 degrees;
- colloid stability at 18 hours;
- waterproof;
- large selection of the packaging value.
Disadvantages:
- as a thickener - soap;
- tube is not very convenient for driving grease into the bearing.
VALVOLINE MOLY FORTIFIED MP GREASE - where it is very humid
Products from the Netherlands have received an EP-complex of additives that reduce friction, and molybdenum disulphide was taken as a basis. Its main advantage was high resistance to water. It does not oxidize when washing under pressure, it does not break out of the knots and reliably blocks access to corrosion. This lubricant showed itself well under shock loads. Its useful mechanical properties persist for a long time.
This composition allows its use in bearings of industrial equipment, agricultural machinery and cars, which are operated in conditions of increased humidity. Manufacturers were able to achieve and record temperatures for this tool, ranging from -150 to +1200 degrees. A black-gray substance can easily be stuffed into the bearing.

What bearing grease to buy
To correctly choose the lubricant, you need to determine the place of its use and the temperature regime of this unit. An important role is played by the amount of incoming moisture and shock loads.
Therefore, the choice of grease can be summarized as follows:
1. For construction equipment whose bearings are subject to severe vibration and overload, Mobil Mobilgrease Special is the best choice.
2. Where high temperatures, for example, in blowers and different air heaters, are placed on their bearings Fuchs Titan Renolit Duraplex EP2.
3. BP Energrease LS-EP 2 will be sufficient for industrial machines, which will not fall out, but one package will last for a long time.
4. In the hubs of cars it is worth using expensive, but time-tested Luqui Moly LM 50.
5. In very wet conditions, for example for car wash equipment or the technique that is often washed, VALVOLINE MOLY FORTIFIED MP GREASE is suitable.
6. Castrol LMX Li-Komplexfett is a reliable tool for construction tools where vibrations and pressure are frequent.
