JNS NA4912 Needle Roller Bearing

JNS NA4912 Machined Ring Type Needle Roller Bearing With Inner Ring, 60mm bore x 85mm outside diameter x 25mm width. Equivalent to IKO NA4912, INA NA4912, NTN NA4912R, Torrington - Koyo NA4912.

Machined type needle roller bearings are high precision bearings which consist of machined outer ring with a complement of needle rollers retained and guided by a cage. The bearings feature a smaller cross-section, higher load-carrying capacity, greater rigidity. Therefore, they are useful in making machinery smaller and lighter.
