JNS NK10/12 Machined Ring Type Needle Roller Bearing Without Inner Ring, 10mm bore x 17mm outside diameter x 12mm width. Equivalent to IKO TAF101712, INA NK10/12 TN, NTN NK10/12 T2, Torrington - Koyo NK10/12.
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.
