JNS NA4900 Needle Roller Bearing

JNS NA4900 Machined Ring Type Needle Roller Bearing With Inner Ring, 10mm bore x 22mm outside diameter x 13mm width. Equivalent to IKO NA4900, INA NA4900, NTN NA4900R, Torrington - Koyo NA4900.

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.
