SC Zero Backlash High Torque Bellows Couplings

SC High Torque Bellows CouplingsSC Series High Torque Bellows Couplings offer maximum flexibility for high torque connection applications.  Using electrodeposited metal bellows, the SC series has a uniqe shape to the bellows convolutions.  By altering the center convolutions to a smaller depth, the SC series coupling offers higher torque capability than the standard FC Coupling product line. The SC series offers zero backlash and minimum wind up to ensure motion instruments are run as efficiently as possible.  The SC coupling line currently has sixteen standard configurations with a variety of bore sizes to make installation simple.
