Structure of Rolling Bearings

Rolling bearings are generally made up of collars (inner, outer), rolling and holding structures. There are several scrolls between the inner and outer rings, which are kept at a certain interval by holding the scrolls and rolling smoothly.

1) Collar (inner ring, outer ring)

The rolling part of the rolling body on the collar is called the raceway, its surface is called the raceway surface, the ball bearing collar has the raceway also known as the channel.

In general, the inner and outer rings in the collar are aligned with the shaft and housing, respectively.

The inner and outer rings of the thrust bearings are called shaft and seat rings respectively.

2) Scrollbody

The scroll is divided into two categories: ball and roller, rollers are divided into cylindrical rollers, rollers, conical rollers, ball rollers and so on according to their different shapes.

3) Cage

The cage is to surround the rolling part so that it is kept at a certain distance in the circular direction.

The cage has a stamping frame, the vehicle body cage, the engineering plastic molding cage.

Bearings with cages have less frictional resistance than full-load ball (roller) bearings with no cages and are suitable for high-speed rotation.
