JNS NK30/20 Machined Ring Type Needle Roller Bearing Without Inner Ring, 30mm bore x 40mm outside diameter x 20mm width. Equivalent to IKO TAF304020, INA NK30/20, NTN NK30/20R, Torrington - Koyo NK30/20.
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.
