JNS NK28/20 Machined Ring Type Needle Roller Bearing Without Inner Ring, 28mm bore x 37mm outside diameter x 20mm width. Equivalent to IKO TAF283720, INA NK28/20, NTN NK28/20R, Torrington - Koyo NK28/20.
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.
