The purpose of lubrication of rolling bearings is to reduce the friction and wear of the internal structure of bearings and avoid burning and sticking. The lubricating effect is shown below.

1, reduce friction and wear

The mutual contact part of the throwing ring, the rolling body and the mouthpiece retainer composed of the bearing is avoided to avoid the contact of metal materials to reduce friction and wear.

2. Increase fatigue life

The rolling fatigue life of bearings increases when the rolling contact area is lubricated well during rotation. On the contrary, the oil viscosity is low, the lubricating oil film thickness is not good, it is reduced.

3, exhaust friction heat, refrigeration

The circulation system can use the gas pedal method to discharge the heat caused by friction, or the heat from the outside world, refrigeration. Avoid bearing overtemperature, avoid lubricating oil itself aging.

4. Others

It also has the actual effect of avoiding dirty things entering the internal structure of the bearing, or preventing rust and corrosion.
