The most important elements of many components and assemblies of the car are bearings. They are intended for the necessary fixing of certain parts in space, they provide rolling, horizontal and vertical movement, and also reduce loads by transferring it to other parts.
In order for the bearings to work most efficiently and reliably, they must be periodically lubricated. At the same time, it is worth remembering that the quality of lubrication is the key to long and reliable operation of the entire mechanism, so you cannot save on lubrication!
Bearing lubrication contributes to: increasing the performance of the entire mechanism and individual parts under high loads, high speeds, humidity or exposure to extreme temperatures. Choosing the right lubricant is based on the type of bearing. So, depending on the type of friction, sliding or rolling bearings can be distinguished. Lubrication for bearings of different types is also different from each other.
Support for the rotation of partsrolling bearings serve as various mechanisms. The basis of their work is rolling friction. They consist of rolling elements, a separator separating them, inner and outer rings. These parts can be ball, thrust, spherical, roller, etc.
Rolling bearing lubrication can be either liquid oil or grease. The qualities of liquid oils include: slight resistance to rotation and good heat dissipation. They protect bearings from wear and stabilize their performance. Greases can provide good corrosion protection and are also able to be easily retained without the need for special sealing. A special grease for wheel bearings is also available.
Support for the guide units are plain bearings. In such nodes, friction occurs when the mating surfaces slide. Here, depending on the direction of the load, radial or axial plain bearings can be installed. Also, depending on the type and mode of lubrication, these bearings are divided into hydrostatic, hydrodynamic, gas-static, gas-dynamic. According to another classification, they are divided into segment, self-aligning, self-lubricating, etc.
Since rolling bearings have certain advantages over plain bearings, they are more common. The lubrication for rolling bearings can be greased to prevent close contact between the workingelements.
It is also important to consider operating conditions when choosing a lubricant: temperature, rotation speed, aggressiveness of the environment, load.
The right bearing grease will allow you to operate your car for a very long time. At the same time, you can avoid significant time and financial costs, which should also be an additional bonus for choosing high-quality material.
