(含：英文原文及中文译文of the bearing is easily avoided. Erosion is characterized by the presence of indentations on the raceways of the bearing ring caused by impact loads or incorrect installation. Erosion usually occurs when the load exceeds the yield limit of the material. If the installation is incorrect so that a load traversing the bearing ring can also produce erosion. The pits on the bearing rings also produce noise, vibration and additional torque.
A similar defect is the elliptical indentation that occurs when the bearing does not rotate due to the ball oscillating between the bearing rings. This kind of damage is called low erosion. This type of damage occurs in both the equipment in transit and the equipment that is still vibrating when not in use. In addition, the debris generated by low-frequency chattering act like abrasive particles and further damage the bearing. Unlike denudation, low charge erosion is often characterized by fretting corrosion that produces a reddish color in the lubricant.

Eliminating the source of vibration and maintaining good bearing lubrication can prevent low load chatter. Isolating the device or isolating the base can reduce the vibration of the environment. In addition, adding a small preload on the bearing not only helps the ball and the bearing ring to maintain close contact, but also helps to prevent the low load eroding generated during the transportation of the equipment.
Causes of bearing seizures are due to lack of internal clearance, improper lubrication and excessive loads. Before it gets stuck, excessive friction and heat soften the bearing steel. Overheated bearings usually change color and generally turn blue-black or yellowish. Friction also forces the cage, which can damage the support frame and accelerate bearing
