Drive Couplings  Zero backlash coupling for use in drive systems where a cost effective coupling is required. A lightweight torque disc aligns one coupling on the motor and one on the lead screw taking out minor misalignment. Torque discs are available separately.

Please note that couplings of different outside diameters will not match together.

A complete coupling consists of 2 x drives of your choice and 1 x torque disc. If you require an inside diameter not listed please enquire, we can modify standard couplings to suit your requirements. If its a small quantity we will do it FREE OF CHARGE.
