Angular contact ball bearings (Standard series)

Superior load-bearing performance.

Withstand combined radial and axial loads; paired single-row or double-row bearings support bidirectional axial loads.

Paired single-row and double-row bearings achieve high rigidity.

High-precision versions support high speed and stable operation.

Single-row angular contact ball bearings use one row of steel balls. Under the same overall dimensions, they can accommodate more steel balls than deep groove ball bearings, offering higher radial load capacity and unidirectional axial load capacity. Different contact angles allow flexible adjustment of radial and axial load ratings. Paired installation realizes bidirectional positioning and higher rigidity. Both open and sealed types are available. High-precision products are ideal for precision positioning and high-speed applications.

Angular contact ball bearings bear combined radial and axial loads and provide high-precision, high-rigidity support to ensure stability and accuracy of high-speed or heavy-load equipment. They are commonly used in machine tools, motors and precision instruments.
