JNS NA499 Needle Roller Bearing

JNS NA499 Machined Ring Type Needle Roller Bearing With Inner Ring, 9mm bore x 20mm outside diameter x 11mm width. Equivalent to IKO NA499, INA NA499, NTN NA499.

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.
