This is a non-separable unit, comprising an inner ring, needle rollers, retaining washers, seal/thrust washers, and an extra-thick outer ring to withstand heavy rolling loads. The end washers are fastened to the inner ring. Type ATF has a single row of rollers. The outer ring of type ATF bearing is crowned. The seals on the ATF bearings are located in counterbores of the outer ring and seal against the O.D. of the end washers, providing a good retention of lubricant and exclusion of foreign material. Seal/thrust washers, made of a self-lubricating resin material, separate the steel thrust surfaces, extending the life of lubricant and bearing. Grooves and holes for relubrication are provided in the inner ring only, since the outer ring must serve as a roller. Type ATF has a groove in the bore of the outer ring for storage of additional lubricant. For protection from corrosion under heavy rolling loads, the O.D. of the bearing is chrome plated. Other exposed surfaces, as mounted, are cadmium or zinc-nickel plated. Inner rings are oxided.

This is a non-separable unit, comprising an inner ring, needle rollers, retaining washers, seal/thrust washers, and an extra-thick outer ring to withstand heavy rolling loads.

Series NBF Airframe track rollers are designed for high load carrying capability, light weight, and for slow rotation or oscillatory motion. They are used in aircraft flap, slat and control applications, and in numerous non-aircraft applications.
Series NBF track rollers are non-separable units, comprised of 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.
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. The NBF series offers a corrosion resistant alternative to conventional yoke type cam followers.
