types of rolling bearings

Rolling bearing is a kind of precision mechanical element that changes the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing friction loss. Rolling bearings are generally composed of four parts: inner ring, outer ring, rolling element and cage. The inner ring is used to match with the shaft and rotate with the shaft; the outer ring is used to match with the bearing seat and play a supporting role; the rolling element is evenly distributed between the inner ring and the outer ring with the help of the cage, and its shape, size and number directly affect the performance and life of the rolling bearing; the cage can make the rolling element evenly distributed, guide the rolling element to rotate and play a lubricating role.

Roller bearings are a type of rolling-element bearing widely used in various industrial applications to support and facilitate rotational motion. They are designed to minimize friction between moving parts and provide smoother operation, higher load capacity, and improved durability compared to other types of bearings.
