Ruland 25.4 mm Outer Diameter 10 mm Bore 38.1 mm Length Aluminium Clamp Style Flexible Coupler FCMR25-10-10-SS

Ruland FCMR25-10-10-SS is a precision-engineered flexible coupler designed for mechanical power transmission applications found in industrial environments including manufacturing, robotics, and fluid power systems.

This coupler features a 25.4 mm outer diameter with matched bore sizes of 10 mm on both ends and a length of 38.1 mm, enabling reliable shaft connections with minimal backlash. The clamp style ensures easy installation and secure attachment to shafts.

Manufactured from 7075-T651 extruded drawn aluminium bar, this coupling offers a lightweight design with low moment of inertia (11.293 x 10-6 kg/m²), enhancing dynamic response and performance at high rotational speeds up to 6000 rpm. Its robust construction supports a torque rating of 5.66 Nm while accommodating misalignment values of 3° angular, 0.38 mm parallel, and 0.25 mm axial, ensuring smooth operation without undue stress on connected components.

Operating temperature range spans from -40°C to 176°C, permitting use in demanding environmental conditions. The coupling complies with DIN 912 12.9 screw standards and meets international environmental regulations including RoHS3 and REACH.

Its six-beam spiral cut design machined from a single aluminium bar provides greater torque capacity and zero backlash compared to single or four-beam alternatives, making it ideal for light duty power transmission tasks such as coupling servo motors to lead screws in automation systems.

Torque rating of 5.66 Nm ensures efficient power transmission. Lightweight aluminium construction reduces inertia for faster system response. Clamp style allows easy installation and secure fastening to shafts. Capability to handle multiple misalignment types reduces wear and extends equipment life.

High maximum speed usage up to 6000 rpm with balanced design minimizes vibration. Operates reliably across wide temperature ranges from -40°C to 176°C. Conforms to rigorous mechanical and environmental standards.

This Ruland coupler is ideal for industrial machinery, robotics, laboratory equipment, and manufacturing applications requiring precise shaft coupling with zero backlash. Its durable materials and design ensure long service life and reliable performance under varied operating conditions.
