Needle roller bearing
Chinabase Machinery (Hangzhou)
Needle roller bearings and cylindrical roller bearings compared relative to its diameter, roller both thin and long. This is called needle. Despite the smaller cross-section, have a higher carrying capacity, therefore, especially suitable for the radial space-constrained applications.
Product Category:
Needle roller bearings are divided into:
1 Radial needle roller and cage assemblies
2.NA, NKI-type needle roller bearings
3.RNA, NK-type needle roller bearings without inner ring
4.HK Needle roller bearings
5.BK Needle roller bearings
Features:
Because the thin and long needle, and therefore the radial structure is compact, its diameter and the same with other types of carrying capacity. Needle roller bearing outer ring nitrogen at high temperature hardening，high wear-resistant surface. Grease a large space, can provide long-term lithium grease lubrication, and extended lubrication intervals. Ring skeleton of nitrile rubber or ST12, the operating temperature range of -30 ° C to 100 ° C or -30 ° C to 180 ° C.
Application:
Main use: automotive, hard drive, variable-speed machine tools and other devices
