Needle bearing (needle bearing) is a roller with a cylindrical roller bearing, relative to its diameter, both the thin and long rollers. Such as needle roller. Despite its small cross section, bearing the load is still high capacity, therefore, especially suitable for the radial space-constrained situations. Needle in the proximal side profile surface Lightly contraction. Needle and the groove line contact results amended to avoid damaging the edge of the stress. Department of thick needle bearing roller bearing outer ring, nitrogen quenching at high temperature, high-precision roller separation by high rigidity outer ring of ribs to guide the use of linear contact wheel can easily turn in the rolling trail, and can under tremendous load. To remove the stress, support the outer wheel design with arc, curve there with a single roller, double seals, without seals, seal rings and other specifications.
