How can we improve?
Angular contact ball bearings support both radial and axial loads through asymmetric races that house the bearing’s spherical rolling elements, also called bearing balls, on an angle. The deeper the angle between the bearing and its axis, the greater the axial load the bearing can carry. Because the axial load is proportionate to the radial load, a greater axial load capacity means less radial load capacity. Angular contact ball bearings come in single- and double-row configurations depending on the direction of loads they carry. Single-row angular contact ball bearings only support axial loads in one direction, while double-row angular contact ball bearings support axial loads in both directions. In addition, we also produce miniature angular contact ball bearings.
Manufactured to the same close tolerances as the radial type, but designed with contact angles of 15, 30, and 40 deg to accommodate greater thrust loads.
Angular contact ball bearings are engineered for use in high-speed, high precision applications for:
* Dental and medical equipment
* General industry
A common choice, at higher precision levels, for applications such as machine tool spindles where both accuracy and high thrust loads are present. They are typically mounted in pairs, also called duplex bearings, providing thrust capacity in either direction and good rigidity for applications where shaft movement is critical.
Double row assemblies offer shaft rigidity, compactness, and higher radial capacity as well as moderate thrust capacity in both directions.
Single row angular contact ball bearings can carry thrust load in one direction only, and should always be adjusted against another bearing which accommodates the opposed thrust load. Single row angular contact ball bearings are no separable.
Spindle bearings are a special design of the single row angular contact ball bearings; they were developed primarily for high-speed work spindles of machine tools. The spindle bearings differ from the angular contact ball bearings by the contact angle, the degree of accuracy, and the type of cage. Spindle bearings are manufactured in series 70 and 72. They are identified by a bearing number commencing with a B.
The design of the double row angular contact ball bearing corresponds to two single row angular contact ball bearings arranged back to back. The bearing is capable of carrying high radial loads and thrust loads in both direction. It is particularly suitable for applications calling for high axial rigidity.
Double row angular contact bearing with unsplit rings are provided with filling slots on one side. The bearings should be mounted in such a way that the main loads are carried by the raceways without filling slot.
* Specific geometry of angular contact bearing raceways and shoulders creates ball contact angles that support higher axial loads.
* Expanded options include special lubricants, cage materials, preloads and coatings for additional corrosion resistance.
