Backlash-Free Coupling

By Design World Staff | April 22, 2007

The BKL/4.5 precision coupling for stepper motors, small servo motors and encoders has a robust and backlash-free coupling flexure, which preserves torsional stiffness. The coupling has an outside diameter of 32 mm and an overall length of 40 mm. It comes in any combination of shaft boxes from 6 to 16 mm (1/4 in. – 5/8 in.), with or without keyways. Max torque rating is 4.5 Nm and max speed is 4,000 rpm.
