What parts does the bearing have
The basic structure of the bearing is made up of four parts: inner ring, outer ring, rolling body (steel ball or roller) and cage.
1. Inner ring (also known as inner sleeve or inner ring) : usually fixed on the journal, and the inner ring rotates with the shaft.The outer surface of the inner ring is provided with grooves for rolling steel balls or rollers, which are called inner grooves or inner raceway.
2. Outer ring (also known as outer ring or outer ring) : usually fixed on the bearing seat or the shell of the machine to support the rolling body.There are also grooves on the surface of the outer ring for rolling steel balls or rollers, called inner grooves or inner raceway.
3, rolling body (steel ball or roller) : each set of bearings are equipped with a group or groups of rolling body, installed between the inner ring and the outer ring, play the role of rolling transmission force.The rolling body is the bearing load parts, its shape, size and quantity determine the bearing load capacity of each high-speed operation performance.
4. Cage (also known as retainer or isolator) : the rolling bodies in the bearing are evenly separated from each other, so that each rolling body can roll normally between the inner ring and the outer ring.
