JNS NA49/32 Machined Ring Type Needle Roller Bearing With Inner Ring, 32mm bore x 52mm outside diameter x 20mm width. Equivalent to IKO NA49/32, INA NA49/32, NTN NA49/32R, Torrington - Koyo NA49/32.
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.
