BK4020 INA Shell Type Needle Roller Bearing with Closed End 40x47x20mm Open Outside length 1397mmSome designs of drawn cup needle roller bearings are closed at one end. They are thus suitable for closing off the shaft ends of bearing arrangements. This provides protection against injury by rotating shafts and protects the bearing against contamination and moisture. Depending on the size, the base is either smooth or lock beaded (stiffened). Due to the profiled base, small axial guidance forces are possible. s. Dimensions Fw: 40mm D: 47mm C: 20mm
