Touch fatigue effect refers to the effect of alternating stress on the nominal bearing operation. Touching fatigue detachment occurs in the name of bearing operation, often accompanied by fatigue cracks. Firstly, it occurs at a greater alternating shear stress below the touch name, and then expands to form different detachment shapes under the name...

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...
