Roller needle roller bearings with cylindrical roller bearings, relative to its diameter, roller both thin and long. This needle roller called. Despite having a smaller cross-section, bearing still has a higher load bearing capacity, an d therefore particularly suitable for radial space is limited occasions.angular contact ball bearings
Needle contour surface at the proximal surface shrink slightly. Needle Roller and raceway line contact amended to avoid produce destructive edge stress. In general engineering bearing can be used in addition to catalogs listed, such as: open Needle roller bearings (1), closed Needle roller bearings (2), needle bearing inner ring (3) and non- inner ring needle roller bearings (4), SKF can supply all types of needle roller bearings: 1, needle roller cage assemblies roller bearings without ribs, self-aligning roller bearings 4, Combined needle roller / ball bearing 5, combined needle roller / thrust ball bearings, combined needle roller / cylindrical roller thrust bearings.

Needle roller bearings
Needle roller bearings, needle bearing outer ring is a thin stamping molding. Its main fea ture is the low sectional height and bear higher load capacity. Mainly used in compact, cheap bearings inside the hole can not be used as a needle roller cage assemblies bearing raceway configuration. Bearings and bearing housings shall install an interference fit. If it can save me shoulder, moving coil axial positioning function, then the bearings inside the hole can be done very simple and economic.bearing roller bearings
 Drawn cup needle roller bearings mounted on the shaft end the the bilateral open type (1) and unilateral closed (2). Closed the drawn cup base end can not withstand the axial guiding force.
 Needle roller bearings are generally attached to the inner ring. Occasions in the journal can not be hardened and ground, can be used in the table inner ring. Hardened steel outer ring Needle roller bearings and needle roller cage assemblies can not be separated. Lubricant storage free space can be extended to add lubrication intervals. Bearings generally use a single-column design. But of wide specifications bearings 1522,1622,2030,2538, and 3038 Series, except they are equipped with two needle roller cage assemblies. The bearing outer ring with lubrication holes. According to user needs, the shaft diameter is greater than or equal to 7mm all single row Needle roller bearings can be equipped with the outer ring with lubrication holes (code suffix AS1).
