JNS NA6903 Needle Roller Bearing

JNS NA6903 Machined Ring Type Needle Roller Bearing With Inner Ring, 17mm bore x 30mm outside diameter x 23mm width. Equivalent to IKO NA6903, INA NA6903, NTN NA6903R, Torrington - Koyo NA6903.

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.
