Angular-Contact Ball Bearings

Angular-Contact Ball Bearings

The raceways of these angular-contact ball bearings have high and low shoulders. The high shoulders of the inner and outer raceways oppose each other, which directs axial, or thrust loads (where the load is parallel to the shaft) through the bearing in one direction. Double-row bearings act like a pair of back-to-back single-row bearings, and can support axial loads in two directions. Angular-contact ball bearings are recommended for applications with moderate to high radial loads (where the load is perpendicular to the shaft) and low to moderate axial loads.

Ball bearings have spherical rolling elements that distribute loads over a small surface area, and they typically create less heat and friction and tolerate higher speeds than roller bearings. To ensure proper functioning, bearings should be lubricated regularly.

General Purpose

These single-row bearings are suitable for most common applications in which the thrust load is in only one direction.

Metric — Steel

Open — 40 ° Contact Angle

Double Row for High Temperatures

Use these bearings for applications that can have axial loads in two directions and high temperatures, such as transmissions, hydraulic pumps, and air compressors. They come prelubricated with high-temperature grease.

Metric — Steel

Double Sealed — 30 ° Contact Angle

Double Shielded — 30 ° Contact Angle

High Precision

Suitable for applications such as centrifuges and industrial pumps, these bearings are manufactured to an ABEC-3 rating for higher precision than general-purpose bearings.

Metric — Steel

Open — 40 ° Contact Angle

For Ball Screw Support Units

Designed for use in ball screw support units, these bearings are manufactured to an ABEC-7 rating and have a higher precision rating than the high-precision bearings.

Metric — Steel

Open — 60 ° Contact Angle

Ultra-High Precision

Manufactured to an ABEC-7 rating, these beatings have a higher precision rating than the high-precision bearings and are designed for applications such as gear reducers, electric motors, and centrifugal pumps.

Metric — Steel

Open — 15 ° Contact Angle
