Deep groove ball bearings mainly bear radial loads and can also withstand both radial and axial loads simultaneously. When it only bears radial loads, the contact angle is zero. When deep groove ball bearings have a large radial clearance, they have the performance of angular contact bearingsand can withstand large axial loads...

The cage in the rolling bearing plays a role in equidistant isolation of the rolling element and preventing it from falling, guiding and driving the rolling element to rotate. Generally speaking, the bearing cage will not be damaged under reasonable working conditions, but incorrect operations in daily production can reduce the service life of the bearing cage...

For each bearing, it has its own limit speed, which is mainly limited by the temperature rise caused by friction heating inside the bearing. When the speed exceeds a certain limit, the bearing will be burned and unable to continue rotating...

When the rolling element is subjected to a load, contact stress will be generated on the contact surface between the rolling element and the inner and outer rings. The inner and outer rings and the rolling element have relative rotational motion during operation, so the contact stress will change....

Lubrication has a crucial impact on the operation and lifespan of rolling bearings. Lubricating grease is made from base oil, thickeners, and additives. The performance of different types and different grades of lubricating grease of the same type varies greatly, and the allowable rotation limit is different. It is important to pay attention when selecting...
