Bell BPS 4162
Bell Helicopter process specification for bearing installation in rotorcraft applications
Bell BPS 4162 is a Bell Helicopter (now Bell Textron) process specification for bearing installation in rotorcraft applications. It covers rotor head, transmission, and flight control bearing installations for Bell 407, 429, V-22 Osprey, and other helicopter platforms, with emphasis on dynamic load and vibration requirements unique to rotorcraft.
Overview
Bell BPS 4162 defines Bell's requirements for bearing installation in helicopter and tiltrotor applications. Rotorcraft bearings experience unique dynamic loads, vibration, and operational stresses that require specialized installation techniques.
The specification addresses rotor head bearings, transmission bearings, flight control bearings, and swashplate assemblies. It includes specific requirements for bearing preload and retention under oscillating loads.
American Precision Assembly provides BPS 4162-compliant bearing installation for Bell helicopter programs, including commercial and military rotorcraft.
