Ruland Mechanical Power Transmission Coupler 38.1 mm OD 15 mm x 12 mm Bore, 57.2 mm Length, 10.73 Nm Torque FCMR38-15-12-A

Ruland FCMR38-15-12-A mechanical power transmission coupler is engineered for precise and reliable torque transfer in light duty power transmission applications such as coupling servo motors to lead screws. Manufactured from a single piece of 7075 aluminium bar stock, this clamp-style coupler features two sets of three spiral cuts, providing enhanced torque capacity, reduced windup, and superior body size compared to single or four beam couplings.

Its balanced design ensures reduced vibration at high speeds up to 6000 RPM, making it suitable for industrial machinery requiring zero-backlash coupling performance. The coupler supports angular misalignment of up to 3°, parallel misalignment of 0.76 mm, and axial misalignment of 0.38 mm, accommodating shaft offsets during operation.

The bores measure 15 mm and 12 mm, and the overall size includes an outer diameter of 38.1 mm and length of 57.2 mm, matching various shaft sizes and applications. The Nypatch® anti-vibration hardware with M5 metric screws enhances screw seating reliability, prevents galling during repeated installations, and maintains a high level of holding power under dynamic conditions.

Constructed from 7075-T651 extruded drawn aluminium bar known for its lightweight yet durable properties, this coupler withstands operating temperatures from -40°C to 107°C. It complies with DIN 912 12.9, REACH, and RoHS3 standards, verifying material and manufacturing quality.

This coupler is ideal for industrial, laboratory, construction, HVAC, manufacturing, and commercial mechanical power transmission needs, providing efficient and precise shaft coupling performance. Its robust metal construction and versatile misalignment capabilities make it suitable for dynamic equipment environments requiring high speed and torque transmission.
