APPLICATIONS:

Angular-contact ball bearings are the most common spindle bearing. They are rolling bearings and consist of one or more rows of rolling balls between concentric grooved rings. They are useful for both radial and axial loads in one direction, and their axial load carrying capacity is determined by the angle at which the load contacts the bearing. The greater the angle, the higher the load capacity.

The most common application for spindle bearings is in machine tool spindles from which the term “spindle bearing” is derived. The bearing has to be capable of handling the particularly demanding operating conditions of the spindle and, as such, has to be specially designed for the application. Depending on the size and type of material being machined by the spindle, the bearing has to cope with a variety of machine speeds, offering maintenance-free and reliable performance within the given design envelope.
