JNS NA6904 Needle Roller Bearing

JNS NA6904 Machined Ring Type Needle Roller Bearing With Inner Ring, 20mm bore x 37mm outside diameter x 30mm width. Equivalent to IKO NA6904, INA NA6904, NTN NA6904R, Torrington - Koyo NA6904.

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.
