Angular contact ball bearings

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

 * Chemical

 * General industry

 * Utilities

 * Turbocharger 

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 angular contact ball bearing
Double row angular contact ball bearingsThe 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 ball bearings may offer some economic benefits as well as handling and mounting benefits versus pairs of Single Row Angular Contact ball bearings; however, they may offer less design flexibility and performance in some cases.Design Attributes * 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. Double Row Angular Contact ball bearings are available in two numerical series:?5200 Series – Lighter load, higher speed, more/smaller balls per bore diameter.?5300 Series – Heavier load, slower speed, fewer/larger balls per bore diameter.If you need help in selecting the best products for your particular application, please remember that design engineering and application assistance are available from LOTTON as part of our value-added services designed to make your job easier.
