Ruland Aluminium Clamp Style Flexible Coupler Bore 12mm x 10mm, 31.8mm OD, 44.5mm Length, 6000 RPM, 5.65 Nm FCMR32-12-10-A

Ruland FCMR32-12-10-A is a precision six beam clamp style flexible coupling designed for mechanical power transmission in industrial applications. Manufactured from high strength 7075-T651 extruded drawn aluminium bar, this coupler combines lightweight design with excellent mechanical properties and low inertia.

At 44.5 mm length, 31.8 mm outer diameter, with bore sizes of 12 mm and 10 mm respectively, this coupler is ideal for connecting servo motors to lead screws where zero backlash and low vibration are critical. The two sets of three spiral cuts provide enhanced torque capacity and reduced windup compared to conventional single or four beam couplings.

It features Nypatch® anti-vibration hardware which ensures consistent screw seating, prevents galling, supports repeated installations, and maintains high screw retention forces. This hardware is metric with M5 screw size for industry compatibility.

Operating reliably at speeds up to 6000 RPM and torque up to 5.65 Nm, FCMR32-12-10-A performs well in light duty power transmission environments. Its axial, angular, and parallel misalignment tolerances optimize shaft alignment absorption, minimizing wear and vibration in system components.

The coupler is RoHS3 and REACH compliant and meets DIN 912 12.9 standards, ensuring environmental and quality compliance for a broad range of industrial setups. It performs under a temperature range from -40°C to 107°C, making it suitable for varied operational conditions.

Constructed from 7075-T651 extruded drawn aluminium bar. Clamp style with hub aluminium material ensures strong mechanical coupling. Maximum speed rating of 6000 RPM for high-speed applications. Torque rating of 5.65 Nm suitable for light duty power transmission.

Zero backlash design reduces vibration and torque losses. Nypatch anti-vibration hardware enhances reliability and maintenance. Operating temperature range from -40°C to 107°C. Compliant with RoHS3, REACH, and DIN 912 12.9 standards.
