3, self-aligning needle roller bearings 

4, combined needle roller / ball Bearing 

5, combined needle roller / thrust ball bearing 

6, combined needle roller / cylindrical roller thrust bearing. STO outer ring without ribs, inner ring support roller RNA22...2RS double-sided seal, no inner ring support roller NA22...2RS double-sided seal with inner ring support roller NATR NATR...PP flat retaining ring axial guide support roller NATV NATV...PP flat retaining ring axial guide support roller, full needle type NUTR rolling element guide support roller, full roller type CRY inch flat ring axial guide support roller 

Needle roller bearing classification 


Needle roller bearings are divided into: 

  1. Centripetal needle roller and cage assembly

  2. NA, NKI needle roller bearings

  3. RNA, NK type needle roller bearing without inner ring

  4. HK type drawn cup needle roller bearing

  5. BK type drawn cup needle roller bearing The drawn cup needle roller bearings mounted on the shaft end are open on both sides (1) and closed on one side (2). The base end face of the closed stamped outer ring can withstand small axial guiding forces.
