Angular Contact Ball Bearing

Angular contact ball bearings are often used in vertical pump motors and vertical/horizontal pumps. These bearings have a heavy axial load carrying capacity as well as the ability to accommodate high speeds.

The most common angular contact ball bearing is designed with a 40-degree contact angle. Many of the super precision designs possess a 15-degree contact angle. Other contact angles are available. The larger contact angle, the higher the resistance to axial loading.

These bearings also come in double row designed to produce both normal and greater than normal (C3) internal axial clearance.

Angular contact ball bearings can be supplied or manufactured flush ground to be mounted in pairs or sets. These can be arranged:

• Back-to-back: the most rigid setup that can accommodate thrust loading in both directions
• Face-to-face: will allow thrust loading in both directions and accommodate some misalignment
• Tandem: will allow for heavy axial loading in one direction only.
