Overview

Deep groove ball bearing

Single row deep groove ball bearings are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types.

Key features

Simple, versatile and robust design
Low friction
High-speed capability
Accommodate radial and axial loads in both directions
Require little maintenance

Typical applications

Electric motors and generators
Pumps, fans, and blowers
Gearboxes and reducers
Conveyors and general industrial machinery

Selection guidance

Select by bore, outside diameter, width, sealing type, internal clearance, speed rating, and actual radial/axial load conditions.
