Product Description

HBB High Performance Single Row Cylindrical Roller Bearing 

Single Row Cylindrical Roller Bearings' assembly does not allow the inclining between inner race's axis and outer race's axis each other, and it is requested that the matched shaft and outer shell holes' processing accuracy shall be higher. If the 2 axis are inclining to each other, contacts between rollers and races will be not uniform and thus will cause stress concentration which will have serious effects on bearings' loading capacity and reduce bearings' life period.

Single Row Cylindrical Roller Bearings cannot limit the axial movement of shaft or outer shell, if need axial limit, it usually needs matching with other types of bearings such as deep groove ball bearings. Only bearings whose inner races and outer races with edges can bear smaller axial loadings.

Single Row Cylindrical Roller Bearings normally do not allow the inclining between shaft and outer shell holes, but under lighter loadings, 2°'s inclining is allowed.

Single Row Cylindrical Roller Bearings are mainly used for large motor, machine tools' main shaft, shaft boxes, diesel engine's crankcase and cars' and tractors' gearboxes.
Single Row Cylindrical Roller Bearings are normally used situations where bigger radial loadings are needed. Due to the linear contact between rollers and races, these bearings' radial loads capacity has a bigger improvement as 1.5-3 times compared with annular ball bearings in same dimensions. Besides, these bearings have better performance for anti-impacting and rigidity, but usually cannot be used to bear axial loads.
