Clamping Control-Arm (8mm REX™ Bore, 48mm Length)

Get a grip on positive-drive motion with the 8mm REX™ Clamping Control-Arm! This all-in-one control-arm is a sleek and simple way to transfer torque from an 8mm REX™ shaft into a linkage in order to actuate mechanisms like an arm, a door, or the claw of a ‘bot.

The profile-matched bore combines with the gorilla-like grip of the clamping mechanism to create a superb hold on an 8mm REX™ shaft. And while it stays tucked away to allow nearby components to move freely, the pinch-bolt remains immediately accessible for easy axial adjustments.

The 4mm thru-holes at the business end of the control-arm bring fine-tuned mechanical options to your application: choose a hole at the end to maximize throw, or use a closer hole to trade-off and maximize torque!
