Needle bearing NCC series

radialcorrosion-resistant

CONSTRUCTION This is a non-separable unit comprising a DCtype needle bearing, inner race, and retaining washers. The end washers are fastened to the inner race. Lubrication grooves and holes are provided in the inner race for all bearings except the 3, 4, and 5 for relubrication purposes. The DC needle bearing can be provided with an oil hole in its outer shell. If so desired, please specify on order. Exposed surfaces, as mounted, are cadmium plated to meet military specifications. These bearings must not be used as rollers. DIMENSIONS Dimensions given below are for the finished bearing after cadmium plating. Only the nominal bearing O.D. is given since the bearing depends on the housing dimensions for its final sizing. Bearings are made to AFMBA and military specifications and are constructed to have low radial clearances when mounted, in order to keep vibration and backlash in mechanisms to a minimum. Shaft diameter and housing bore dimensions necessary to mount these bearings properly are given on the facing page.
