Ruland Mechanical Power Transmission Clamp Style Coupler 25 mm OD 12 mm Bore 10 mm Bore 38.1 mm Length FCMR25-12-10-A

Ruland FCMR25-12-10-A Mechanical Power Transmission Coupler is a clamp style flexible coupling machined from a single piece of high quality 7075-T651 extruded drawn aluminium. Featuring a 25 mm outer diameter and dual bores sized 12 mm and 10 mm, it measures 38.1 mm in length, making it ideal for power transmission in servo motor to lead screw applications and other light duty machinery.

This spiral beam coupling is engineered for precision with zero backlash to maintain accurate torque transmission and a balanced design to minimise vibration at speeds up to 6000 rpm. It incorporates six spiral cuts that enhance its torque capacity and reduce windup compared to single beam couplings.

Designed to accommodate angular, parallel, and axial misalignments of 3°, 0.38 mm, and 0.25 mm respectively, the coupling ensures reliable mechanical flexibility and alignment compensation. The included M4 stainless metric screws conform to DIN 912 12.9 standards and feature Nypatch® anti-vibration hardware to prevent galling, maintain holding power, and allow repeated screw installations.

Operating reliably across a temperature range from -40°C to 107°C, this coupling complies with RoHS3 and REACH standards, making it suitable for industrial, manufacturing, automation, and laboratory equipment environments. Its construction from lightweight aluminium also contributes to a low moment of inertia (4.12 x 10-6 kg/m²), enhancing dynamic response and efficiency.

Ruland manufactures this coupling at their Marlborough, MA facility, employing proprietary processes and North American sourced bar stock to assure high quality. This product is especially suited for mechanical power transmission, material handling, and automation systems.

Constructed from high-strength 7075-T651 extruded drawn aluminium bar for lightweight and durability. Supports maximum speed of up to 6000 rpm suitable for servo motors and light duty applications. Rated torque capacity of 2.82 Nm ensuring reliable performance under load.

Accommodates angular, parallel, and axial misalignments with 3°, 0.38 mm, and 0.25 mm tolerances respectively. Equipped with metric M4 screws conforming to DIN 912 12.9 standards for secure fastening. Operating temperature range from -40°C minimum to 107°C maximum for versatile industrial environments.

Zero backlash design with balanced construction to reduce vibration during high speed rotation. Compliant with RoHS3 and REACH environmental standards for safe industrial use.
