Product Description

 

 

Deep groove ball bearings are the most representative of rolling bearings, with simple structure, They are easy to use and versatile .
Such bearings are non-separabal bearings,the inner and outer rings are rolled into a ditch arc type. They can bear radial load and axial load,with low coefficient of friction,high limiting speed .They are suitable for high-spped,low noise ,low vibration occasions. Deep groove ball bearings are widely used in auto-mobiles, machine tools, motors, instrumentation, construction machinery, railway vehicles, agricultural machinery and various equipment in machinery industry.

Q: What precautionary measures I should adopt before installation of bearings?
A: Firstly, doesn't need to remove the preservative coating of the bearings. It is necessary to wipe off the outside          cylindrical surface and bore, if the grease is not compatible with the preservative then wash and carefully dry the      bearing. Bearings should be installed in a dry, dust-free room away from metal working or other machines producing swarf and dust.
