HK1512-B INA Drawn Cup Needle Roller Bearing 15x21x12mm
Dimensions - d (inside diameter) 15mm Dimensions - D (outside diameter) 21mm Dimensions - B (width) 12mm INA Drawn cup type needle roller bearing with open end 15mm Inside x 21mm outside x 12mm wide
Due to the thin walled outer cup and the design without an inner ring, drawn cup needle roller bearings have extremely small radial dimensions. They have high load carrying capacity, are suitable for high speeds and are particularly easy to fit.
Drawn cup needle roller bearings require a hardened and ground bearing raceway on the shaft. If the shaft cannot be used as a raceway, they can be combined with inner rings IR or LR.
