Special bearings for vibration:
A. The diameter of the rolling elements increases, and the length of the rolling elements increases. B. The cage guides the rollers by the outer ring ribs to reduce the force on the rollers. C. The inner ring is used to guide the rollers to improve the roller operation. D. The cylindrical roller bearing cage adopts an integrated structure, which greatly improves the strength. E. The outer diameter of the self-aligning bearing is designed with oil groove and oil hole, which has good lubrication effect.
