Overview

Deep groove ball bearing

Deep groove ball bearings are the most widely used, versatile bearing type. With deep raceway grooves in both rings, they accommodate radial loads and axial loads in both directions simultaneously. Their simple design enables low friction and high-speed operation, and seal/shield variants retain lubricant and exclude contamination. They serve as standard components in motors, pumps, gear units and a wide range of equipment.

Key features

Accommodate radial and bidirectional axial loads
Low friction, high-speed capable
Seal/shield options reduce maintenance
Highly versatile and interchangeable

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.
