Rotary Mechanical Control Cables


Cable	Steel Cable Core with Plastic Cover

Cable with Plastic Cover and Plain Bearings

Transmit rotary motion to operate valves, throttle controls, and HVAC damper controls. These cables are flexible, so you can weave them around obstructions to manipulate controls from a distance. They have a D-profile shaft on one end for installing a manual control knob and a set screw on the other end for securing to a shaft. Push the male end of the shaft through a panel cutout and secure with locknuts.

Plastic Cable Cover—Cables with a plastic cover protect the core from bending. The cover also helps to prevent injury from the rotating cable.

Plain Bearing—Cables with plain bearings last longer than cables without them because the bearings support the connection between the coupling and core.
