Ruland Aluminium Clamp Style Flexible Coupler 31.75 mm OD 12.7 mm Bore 44.45 mm Length FCR20-8-8-A

Ruland FCR20-8-8-A is an aluminium clamp style Flexible Coupler engineered to accommodate higher speeds, greater misalignment, and limited lubrication conditions exceeding standard coupling capabilities. This one-piece construction eliminates mechanical joints, thereby enhancing reliability and torsional rigidity with zero backlash. The coupling features a clamp style fixing mechanism utilizing an M5 socket head cap screw per shaft, ensuring secure and easy installation.

With an outside diameter of 31.75 mm, a length of 44.45 mm, and bore sizes of 12.7 mm on both ends, this coupling supports a maximum rotational speed of 6000 rpm and a torque rating of 55.6 Nm. It effectively manages misalignment with allowances of up to 3° angular, 0.38 mm parallel, and 0.25 mm axial displacement, making it suitable for high precision applications where shaft misalignment is expected.

The coupling’s aluminium material provides an excellent strength-to-weight ratio and is suitable for operating temperatures from -40°C to 107°C, supporting a wide range of industrial environments. Typical uses include encoders, stepper motors, robotics, measuring instruments, servo systems, pumps, valves, and fans in industrial, manufacturing, and automation sectors.

Its torsionally rigid design minimizes vibration and torsional windup, making it ideal for applications requiring constant velocity coupling with high torque capacity and reversible operation. No lubrication is required, reducing maintenance and operational costs.
