Product Introduction

Case Carburizing
The case carburizing process forms a hardened steel "case" on the exterior of the bearing while leaving a soft core. The combination of the hard surface layer surrounding the soft core provides excellent impact load capacity. Case carburizing can increase the theoretical bearing life by 40%, thereby extending maintenance intervals and reducing downtime.

Special Roller Crown
NTN's pioneering efforts in developing barrel-shaped rollers have resulted in greater load-carrying capacity and longer bearing service life. The crowned rollers under load distribute stress evenly along their entire length of contact with the raceway, thus eliminating stress concentration at the roller ends. This design concept also compensates for minor misalignments between the shaft and housing bore as well as deflection under load, thereby reducing stress concentration.

Comprehensive Product Coverage
NTN offers tapered roller bearings in ISO (metric), inch and J-metric series, available in single-row (taper/taper), double-row (back-to-back or face-to-face), double-row (double cup or double cone) and four-row assemblies. NTN products allow customers to optimize the selection of tapered roller bearings through customized geometries and surfaces, ensuring the delivered products meet customer requirements.
