Tapered Roller Bearing - Single Row
- On Sale Till 07/03/2025
- Volume Discount
Tapered roller bearings utilize conical rollers and raceways, arranged so that the rollers and raceways meet at a common apex. The rollers are guided by contact between the large end of the roller and a rib on the inner ring. This provides high capacity for radial and single thrust loads.
NTN’s pioneering efforts in developing crowned rollers have resulted in greater load-carrying capability and longer bearing life. Crowned rollers under load distribute stress equally along their full length of contact with the raceways, thereby eliminating stress concentration at the roller ends. This design concept also compensates for minor misalignment between shaft and housing bore and deflection under load, thereby reducing stress concentration.
