JNS NA4910UU Needle Roller Bearing

JNS NA4910UU Machined Ring Type Sealed Needle Roller Bearing With Inner Ring, 50mm bore x 72mm outside diameter x 22mm width. Equivalent to IKO NA4910UU, INA NA4910.2RS, NTN NA4910LL, Torrington - Koyo NA4910.2RS.

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.
