7208 b bearings have raceways on the inner and outer rings

7208 b bearing angular contact ball bearings have raceways on the inner and outer rings, and the inner and outer rings are relatively shifted in the axial direction of the bearing.This means that the bearing ring is designed to withstand composite loads, namely radial and axial loads acting simultaneously.
The axial load capacity of 7208 b bearing angular contact ball bearing increases with the increase of contact Angle.The contact Angle α is defined as the Angle between the line connecting the ball and raceway contacts in the radial plane and a line perpendicular to the bearing axis, along which the load is transferred from one raceway to another.

7208 b can bear radial load and axial load at the same time.It can work at high speed.The larger the contact Angle, the higher the axial bearing capacity.
7208 b bearing feature
1, general assembly bearings
General purpose assembly bearings are specially engineered so that when the bearings are mounted close to each other, any combination can achieve a given internal clearance or preload, as well as an average load distribution, without the use of gaskets or similar devices.

Pair bearings are used when the load carrying capacity of a single bearing is insufficient (using cross-link configuration) or when combined loads or axial loads acting in two directions (using back-to-back or face to face configuration) are to be borne.
2, the basic design of the 7208 b bearing (can not be used as a general assembly), for the configuration of a single bearing
The basic design of single-row angular contact ball bearings 7208 b is mainly used in configurations with only one bearing in each position.The width and protrusion are normal tolerances.Therefore, it is not suitable to install two single row angular contact ball bearings close together.
