JNS NA497 Needle Roller Bearing

JNS NA497 Machined Ring Type Needle Roller Bearing With Inner Ring, 7mm bore x 17mm outside diameter x 10mm width. Equivalent to IKO NA497, INA NA497, NTN NA497.

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.
