JNS NA4906 Needle Roller Bearing

JNS NA4906 Machined Ring Type Needle Roller Bearing With Inner Ring, 30mm bore x 47mm outside diameter x 17mm width. Equivalent to IKO NA4906, INA NA4906, NTN NA4906R, Torrington - Koyo NA4906.

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.
