3977/3920 TAPERED RB
  • NTN tapered roller bearings are designed for the most demanding applications in industries such as mining, forestry and steel manufacturing.
  • Utilizing conical rollers and raceways arranged so that the rollers and raceways meet at a common apex, NTN’s tapered roller bearing rollers are guided by contact between the large end of the roller, providing high capacity for radial and single thrust loads.
  • With almost 100 million tapered roller bearings manufactured every year under the NTN and Bower brands, it’s no wonder that NTN rivals all major competitors on the market.
