Hm803149 Tapered Roller Bearing

Structure: Railway bearings are generally composed of inner ring, outer ring, rolling body and cage and other components. The inner ring is directly connected to the shaft, the outer ring is installed on the wheel, and the rolling body is located between the inner and outer rings, which reduces friction through rolling and maintains the normal operation of the bearing. The cage is an important part used to fix the rolling element and ensure the relative position of the rolling element.

Function: The main role of railway bearings is to support and guide the rotation of the railway vehicle axle, bear the weight of the train, and reduce the friction during operation to ensure that the train runs smoothly and efficiently. The quality and performance of railway bearings directly affect the safety, stability and durability of trains.
