Sell bearings

Description

Deep groove ball bearing is generally made of bearing steel (9Cr*8), stainless steel (AISI**0C, AISI**4, AISI**6) and ceramics. It is an important member of ball bearing and the most common used rolling bearing. The structure is very simple. Furthermore, deep groove ball bearing usually used for bearing the radial load. It can be easy to operate and has the performance of angular contact bearing assembly, while the radial play is increasing. In that case, it can bear the axial loads and radial loads together. Besides, in some case, it can be used for standing purely axial loads. When the size is same, comparer with other bearings, deep groove ball bearing enjoys smaller coefficient of friction and higher limits speed. This kind ball bearing can not stand impact, so it is not suitable for heavy load. Finally, deep groove ball bearing has higher load rating for their size than shallow-groove, but is also less tolerant of misalignment of the inner and outer races. A misaligned shallow-groove bearing may support a larger load than the same sized deep-groove bearing with similar misalignment. There are some advantages such as less coefficient of friction, less vibration and noise, less energy consumption, high limiting speed, large size range and variations of structure. Therefore, it is widely used in automobile, tractor, engine bed, electrical machinery, water pump, agricultural machinery and fabrics machine etc.
