JNS NA4902 Needle Roller Bearing

JNS NA4902 Machined Ring Type Needle Roller Bearing With Inner Ring, 15mm bore x 28mm outside diameter x 13mm width. Equivalent to IKO NA4902, INA NA4902, NTN NA4902R, Torrington - Koyo NA4902.

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.
