JNS NA6901 Machined Ring Type Needle Roller Bearing With Inner Ring, 12mm bore x 24mm outside diameter x 22mm width. Equivalent to IKO NA6901, INA NA6901, NTN NA6901R, Torrington - Koyo NA6901.
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.
