Piper 452-429 Bearing, Roller, Needle

This is a non-separable unit, comprising an inner ring, needle rollers, retaining washers and outer ring made extra-thick to better withstand rolling loads. The end washers are fastened to the inner ring. Type NBF has a single row of rollers.

Lubrication grooves and holes are provided for relubrication in the inner ring only, since the outer ring must serve as a roller.

For protection from corrosion under the heavy rolling loads, the O.D. of the bearing is chrome plated. Other exposed surfaces, as mounted, are cadmium plated,or zinc-nickel plated.
