Product Description

Product Description

 

SDBOY needle roller bearings are bearings with cylindrical rollers that are small in diameter relative to their length. The modified roller/raceway profile prevents stress peaks to extend bearing service life.
SDBOY supplies needle roller bearings in many different designs, series and in a wide range of sizes, which makes them appropriate for a wide variety of operating conditions and applications.

Classification of needle roller bearings:

1) Radial needle roller and cage assembly
2) RNA, NKI type needle roller bearings
3) RNA, NK type needle roller bearings without inner ring
4) HK type drawn outer ring needle roller bearings
5) BK type drawn outer ring needle roller bearings
Drawn outer ring needle roller bearings mounted on the shaft end are double-sided open type (1) and single-sided closed type (2). The base end face of the closed drawn outer ring can withstand very small axial guide force.
