JNS NA6918 Machined Ring Type Needle Roller Bearing With Inner Ring, 90mm bore x 125mm outside diameter x 63mm width. Equivalent to IKO NA6918, INA NA6918, NTN NA6918R, Torrington - Koyo NA6918.
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.
