Description

Needle in the proximal surface of the surface profile is slightly contracted. Needle roller and the results can be modified line contact needle roller bearings
Avoid damaging the edge of the stress. Bearing needle roller bearing outer ring line thick, high temperature nitrogen quenching, high-precision separation of the roller by the high rigidity of the outer ring wall to guide the use of linear contact wheel can easily turn in a raceway, and can under heavy load. For the removal of stress, support the use of arc outer wheel design, a wheel with a single curve, double seals, without seals, seal rings and other kinds of models.
