Description of Deep Groove Ball Bearing:

Deep groove ball bearings are most commonly used rolling bearings. Because of their versatility, single-row deep-groove ball bearings are the most popular of the antifriction bearing types. They are available in a broad range of sizes, from miniature ball bearings with outside diameter of less than 9mm to extra-large bearings that exceed 1,500mm in diameter. Small and mid. size bearings are also available in a variety of shield, seal and snap ring arrangements. Big ones normally are fitted with solid brass or steel cages.

Features of Deep Groove Ball Bearing:

1) Deep groove ball bearings mainly take radial load as well as take moderate axial load

2) With less coefficient of friction, high limiting speed, large size range and various structure

3) They are suitable of precision instruments, low noise motors, automobiles, motorcycles, and other common machinery

4) A widely used type of bearings in machinery industry

Advantages of Deep Groove Ball Bearing:

• Sustain radial, axial, or composite loads.
• Provide both high-running accuracy & high-speed operation
• Can replace high speed angular contact ball bearings
• Simple design
• Maintenance free
• Longer service life
