💡 What is a torque tube bearing used for?
Torque tube bearings are commonly used in control systems, robotic arms, and light motion assemblies where compact, low-resistance rotation is required. They're built for precision movement - not high speed or flight-critical applications.

Ideal for motion control setups and non-aircraft engineering tasks needing tight tolerance and smooth rotation.
