PRODUCT DETAILS

7000AC Series Angular Contact Ball Bearings also known as single direction angular contact ball bearings or 25° contact angle bearings, features a 25° contact angle (α=25°).

These non-separable precision bearings are engineered to efficiently handle combined radial loads and single-direction axial loads, with optimized inner and outer ring shoulder heights to accommodate more steel balls—greatly enhancing load capacity and operational stability.

Key Features:

25° contact angle design for combined radial and axial load support

Non-separable structure ensures rigid alignment in high-speed operations

Increased steel ball loading boosts load capacity and service life

Available in open, sealed, and shielded configurations

Applications:

Widely used as machine tool bearings, automotive bearings, aircraft bearings, electric motor bearings,

and robotics bearings in precision industrial equipment.

Category Overview

Angular Contact Ball Bearings are designed with contact angles between the balls and raceways, enabling them to carry combined radial and axial loads simultaneously as well as unidirectional thrust loads. With high rigidity, high running accuracy, and high-speed performance, they are widely used in precision machinery, machine tools, pumps, motors, and equipment requiring precise axial positioning.We supply single-row, double-row, and matched bearing configurations to meet different precision, speed, and load requirements.
