The design of the stamping outer ring needle roller bearing features in where

Drawn cup needle roller bearing is a thin outer ring needle roller bearing, stamped more general needle roller bearing, in addition to the different shape structure, more is still the performance in terms of function. What are actually drawn cup needle roller bearing features? Because stamping outer ring needle roller bearing of cross section height is low, so it can accept load is higher, it can be used to rely on this structure is compact, the price is cheap and bearing hole not a needle in the race of bearing cage components and equipment. Because of the particularity of structure, stamping outer ring needle roller bearing and bearing housing device is necessary to do cooperation method, if can save box axial positioning function such as shoulder, retaining ring, bearing the hole in the cabinet can manufacture extremely brief and economy. Observed and stamping outer ring needle roller bearing on the shaft end of two side open and one closed type two kinds, satisfied with different conditions, which closed drawn cup base face can accept small axial guiding force. Drawn cup needle roller bearings are generally not attached to the inner ring, the journal cannot quench hardening and grinding, can use inner ring. Under normal circumstances, stamping outer ring needle roller bearing hardening steel outer ring needle roller and cage components not separation, and storage of smooth agent of free space can make up for the smooth distance for longer periods; Bearing outer ring also has a smooth oil hole design, according to user requirements, shaft diameter greater than or equal to 7 mm all single drawn cup needle roller bearing can be equipped with smooth oil hole of the outer ring.
