JNS NA4830 Needle Roller Bearing

JNS NA4830 Machined Ring Type Needle Roller Bearing With Inner Ring, 150mm bore x 190mm outside diameter x 40mm width. Equivalent to IKO NA4830, INA NA4830, NTN NA4830, Torrington - Koyo NA4830.

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.
