When a load is applied to an angular contact ball bearing, elastic deformation and the amount of stress at the contact point changes as a result of the varying load conditions of the balls, inner ring, and outer ring according to the contact angle of the bearing. Figure 1.2 illustrates loads acting on two rolling elements for a 30? contact angle, and a 15? contact angle. The relation between an axial load being applied to the bearing and resulting load acting on the rolling element can be formulated as: Fa/(Number of balls × sinα).

Therefore, the larger the contact angle, the smaller the load acting on the rolling element. Load at the contact point, and its consequential deformation, is reduced thus resulting in longer life. When a radial load is applied, the smaller the contact angle, the smaller the load acting on the rolling element, thus resulting in reduced load at the contact point. (See Pages 42 and 43 for contact angle specifics.)

Standard

Single-row angular contact ball bearings have a line connecting the contact points drawn in the radial direction, which is called the contact angle. The contact angle makes this bearing suitable for accommodating radial loads, single direction axial loads, and a combination of both. Furthermore, since an axial component is generated when a radial load is applied, these bearings are generally used in pairs, triplex sets, quadruplex sets, or multiplex sets.

For permissible axial load, please refer to Page 147. For application of limiting speeds, please refer to Page 170. When a ceramic ball is used, limiting speed value will be 1.25 times the value of steel ball. Note: Bearing numbers with a “C” suffix: nominal contact angle 15? Bearing numbers with an “A5” suffix: nominal contact angle 25?
