Product features details

Structure and features

Angular Contact Ball Bearings are non-separable bearings, and the straight line connecting the contact points between the balls and the inner and outer rings has a certain angle (contact angle) with respect to the radial direction (see Fig. 1). The contact angle and contact angle symbol are shown in Table 1.
A radial load and a unidirectional axial load can be applied. Also, when a radial load acts, an axial component force is generated, so 2 pcs. are generally used facing each other. Table 2 shows Angular Contact Ball Bearings, and Table 3 shows Combined Angular Contact Ball Bearings.
Please refer to Precision Rolling Bearing (CAT.No.2260/J) for bearings with a contact angle of 15° and bearing accuracy of JIS Class 5 or higher.

Table 2 Classification and characteristics of Angular Contact Ball Bearing

ClassificationFeatures
Standard type·The bearing series includes 79, 70, 72, 72B, 73 and 73B.
·The contact angles are 30° and 40° (with B).
·The standard retainer type depends on the bearing model.
 

Table 3 Combination type and characteristics of Combined Angular Contact Ball Bearings

Combination TypeFeatures
Bottom combination (DB)・ It can receive radial load and axial load in both directions.
·Since the distance l between the points of action of the bearing is large, the load capacity of the moment load is large.
·The allowable tilt angle is small.
Front combination (DF)・ It can receive radial load and axial load in both directions.
·The distance l between the points of action of the bearing becomes smaller, and the load capacity of the moment load is small.
・ The permissible tilt angle is larger than the back combination.
Parallel combination (DT)·Can receive radial load and unidirectional axial load.
·Since 2 pcs. receive an axial load, a large axial load can be received.

Since it is manufactured as a set to adjust the internal clearance or preload of the bearing, bearings with the same product number must be used in combination.
