About Ball Bearing

A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. Its main purpose is to reduce rotational friction and support radial and axial loads. Ball bearings are widely used in machinery, vehicles, and industrial equipment because they enable smooth motion, high speed, and long service life with minimal maintenance.

Ball Bearing Types

Single Row Deep Groove Ball Bearing

Single row deep groove ball bearings are the most widely used roller bearing type in the world due to their versatility and overall performance. They are characterized by deep raceway grooves with arcs slightly larger than the ball radius.

Magneto Ball Bearing

Designed for limited space and easy assembly, magneto bearings were originally used in early magnetos (engine electrical generators). Today, they’re used in many compact machines.

Double Row Self-Aligning Ball Bearing

With two rows of balls and a spherical raceway, these bearings automatically align to compensate for shaft misalignment or housing deformation.

Single Row Angular Contact Ball Bearing

Angular contact bearings handle both radial and axial loads. Single row types support axial loads in one direction, while double row types handle loads in both directions.

Double Row Angular Contact Ball Bearing

Angular contact bearings handle both radial and axial loads. Single row types support axial loads in one direction, while double row types handle loads in both directions.

Single Row Duplex Ball Bearing

Duplex bearings pair two single row bearings for greater load capacity and precise axial positioning. Common in machine tool spindles and precision equipment.
