💡 What is an airframe control bearing used for in aerospace systems?
Airframe bearings are made for precision movements in aircraft control surfaces and structural joints.

• Used in rudder, elevator, or torque tube mechanisms

• Handles high radial and thrust loads despite low weight

• Built to withstand vibration, fatigue, and tight tolerances

Tough enough for aircraft, smooth enough for control.
