Airframe Control Bearings

Made in USA Airframe Control Bearings

Schatz Bearing Corporation of Poughkeepsie, New York manufactures airframe control bearings for flight control systems, drive systems, stabilizers, flaps, slats, and spoilers. These Made in USA aircraft bearings combine precision manufacturing with axial and radial positioning and oscillatory motion. Airframe control bearings from Schatz are designed for high loads and made of corrosion-resistant materials. They include both single-row and double-row designs and can be sealed for environmental resistance. Airframe bearings and long lead times don’t mix, so partner with Schatz and see why we have won numerous Boeing Performance Excellence Awards.

Airframe control bearing Features

Supplied with MIL-PRF-81322 or MIL-PRF-23827 approved greases, or other lubricants.
Zinc Nickel (AMS2417) or Cadmium plated (QQ-P-416E) to resist corrosion, including galvanic corrosion.
Made of AISI 52100 steel, AISI 440C corrosion resistant stainless steel, 440C modified, M50, or CREN stainless steel with superior resistance to corrosion and fatigue.
Available in higher precision levels and with lower starting torques.
Angular contact bearings can be mounted as single bearings or in pairs (as a duplex set) for increased axial capacity and rigidity.

Types of airframe Control Bearings

There are several different types of airframe control bearings. Examples include:

Single-row or double-row deep groove bearings and misaligning bearings
Thin section bearings
Spherical plain bearing
Plain rod ends (rose joins)
Plain bushings (journals)

Replacing Precision Bearings

During the life of an aircraft, precision bearings that are used frequently may be replaced several times. Typically, these airframe control bearings are used with:

Control linkages
Actuation devices
Undercarriage components
Hydraulic links
Door mechanisms
Engine controls
