Ruland 38.1 mm Outer Diameter Aluminium Clamp Style Flexible Coupler 15 mm Bore 57.2 mm Length FCMR38-15-15-A

Ruland FCMR38-15-15-A is a high-performance flexible coupler machined from a single piece of 7075 aluminium bar stock, with 38.1 mm outer diameter, 15 mm bore size on both ends, and a length of 57.2 mm. This clamp style coupler features two sets of three spiral cuts, providing increased torque capacity and reduced windup compared to single or four beam couplings.

Designed for light duty power transmission applications during which precise, backlash-free motion is critical, it excels in coupling servo motors to lead screws where vibration reduction and balanced rotation at speeds up to 6000 RPM are required.

The coupler includes metric Nypatch anti-vibration hardware that ensures reliable screw seating, prevents galling, and maintains high holding power through repeated installations. It tolerates angular misalignment up to 3°, parallel misalignment of 0.76 mm, and axial misalignment of 0.38 mm, enhancing the durability and flexibility of mechanical assemblies.

Constructed to operate within a temperature range of -40°C to 107°C, FCMR38-15-15-A complies with international standards including REACH, RoHS3, and DIN 912 12.9, ensuring safety and compatibility in industrial environments. The lightweight aluminium construction results in low moment of inertia, promoting rapid and controlled movements.

Manufactured in Ruland's Marlborough, MA facility under stringent quality controls, this coupler is ideal for industrial, manufacturing, laboratory, and automation use cases requiring precision and reliability.

Constructed from high-strength 7075 aluminium alloy. Clamp style design with two sets of three spiral cuts for enhanced torque. Zero-backlash coupling suited for servo motor to lead screw connections. Balanced design minimizes vibration at speeds up to 6000 RPM.
