Airframe track rollers and needle bearings are designed for high load carrying capability, light weight, and slow rotation or oscillatory motion. The exposed surfaces are plated to provide corrosion resistance. They are used in aircraft flap, slat and control applications, and in numerous non-aircraft applications.
Series NBL track rollers are designed with heavy outer ring cross section for track roller applications. They offer a corrosion resistant alternative to conventional yoke type cam followers.
