Bearing overheating may be due to not properly installed, the skew the installation will cause the ball is not in the correct position of the bearing raceway rolling, and even caused a larger ball end face and the bearing inner race and the outer race block Taiwan's axial force, resulting in bearing overheating.
Another possibility is the imprecise measurement of the size of the shaft and bearing hole or the mating surface roughness did not meet the standard requirements, resulting in too large an interference fit, so that the bearing seat severely extruded, leading to the bearing itself, reduce the radial clearance, angular contact ball bearings rotate difficulties, fever, increased wear and tear or stuck in severe cases can cause the bearing inner and outer races installation.
All bearings in the anti-friction bearings are basically contains two hardened steel ring, a plurality of hardened balls or rollers, as well as a separation of the separation of the rollers or the roller frame or holder. These types in use is divided into many types. Some types, such as bearings, needle column may not be the inner ring, the rollers directly hardened shaft movement.
In practice it is necessary to use more than the recommended amount of grease is yes. Only need very little grease can be done when the required torque is low, the lubrication of the bearing. Very low speed and bearing exposed to dust or moisture in the bearings might almost be filled. Angular contact ball bearings in high-speed and high-temperature conditions require more frequent lubrication is usually higher than the general case.
