Product Description
Ruland FCMR38-12-12-A Aluminium Clamp Style Flexible Coupler is engineered for demanding mechanical power transmission applications requiring precise alignment and high rotational speeds. It has a 38.1 mm outside diameter, 57.15 mm length, and accommodates 12 mm bore shafts on both ends.
This coupler’s aluminium construction provides an optimal balance of strength and reduced weight, allowing for efficient torque transmission up to 12.43 Nm and speeds reaching 6000 rpm. The clamp fixing style uses one socket head cap screw per shaft, enabling secure mounting and ease of installation.
The flexible six-beam design compensates for up to 3° angular misalignment, 0.76 mm parallel misalignment, and 0.38 mm axial misalignment, making it ideal for applications where shaft alignment may vary. Its one-piece torsionally rigid body eliminates backlash and mechanical joint failure risks, enhancing durability and reliability.
Operating temperature range from -40°C to 107°C ensures suitability in a variety of industrial environments without the need for lubrication. This coupling conforms to RoHS3, REACH, and DIN 912 12.9 standards, demonstrating adherence to safety and quality requirements.
Typical applications include encoders, stepper motors, robotics, measuring instruments, servo systems, pumps, valves, and fans in industrial, laboratory, and manufacturing settings.
