NTN Americas | Needle Roller BearingsNeedle bearings use small needle rollers as rolling elements. These thrust &, caged needle bearings feature a smaller cross·section, higher load·carrying capacity, greater rigidity, and lower inertia forces that facilitate size and weight reductions in machinery.
NTN Roller Bearings | MISUMINTN’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|
