Characteristics of spindle bearings

Spindle bearings are single row angular contact ball bearings comprising solid inner and outer rings and ball and cage assemblies with solid window cages. They cannot be dismantled. The bearings are available in both open and sealed versions.

Spindle bearings have restricted tolerances. They are particularly suitable for where requires very high guidance accuracy and speed capacity, especially for slewing part of the main spindle of machine tool.

Angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis. This means that they are designed to accommodate combined loads, i.e. simultaneous radial and axial acting loads.
The axial load carrying capacity of angular contact ball bearings increases with the enlarging of contact angle. The contact angle ? is defined as the angle between the line joining contact point of the ball and the raceways in the radial plane, along which the load is transmitted from one raceway to another, and a line perpendicular to the bearing axis.

Single row angular contact ball bearings can accommodate axial loads acting in one direction only. Under radial loads a force acting in the axial direction is engendered in the bearing, and this force must be counteracted. Consequently the bearing is normally adjusted via a second bearing.

Single row angular contact ball bearings have one high and one low shoulder. Some bearings, particularly those of Diameter Series 8 and 9, have an inner ring with two high shoulders as a deep groove ball bearing. The low shoulder on one or both rings enables a large number of balls to be filled in the bearing, thus giving the bearings a relatively high load carrying capacity. They are of inseparable design.
