NKXR Combined Needle Roller Bearings — Sizes & Specifications

The NKXR series is a combined bearing pairing a radial needle roller bearing with a thrust cylindrical roller section, for higher axial loads than the ball-type NKX in the same envelope. Typical uses are machine-tool and heavy gearbox shafts. BPK supplies NKXR10 to NKXR70 by bore, factory-direct from Yandian, Shandong, for importers, distributors and OEM buyers.
