Ruland Flexible Coupler 31.8 mm OD, 10 mm and 8 mm Bore, 44.5 mm Length, Clamp Style, Aluminium FCMR32-10-8-A

Ruland FCMR32-10-8-A flexible coupler is engineered for light duty power transmission, coupling servo motors to lead screws with high precision and reliability. This clamp style coupling features a 31.8 mm outer diameter, 44.5 mm length, and bores measuring 10 mm and 8 mm, designed to accommodate different shaft sizes securely.

Constructed from 7075-T651 extruded drawn aluminium bar, it ensures lightweight properties with low inertia, critical for high-speed operations up to 6000 rpm. The six beam design with two sets of three spiral cuts increases torque capacity to 6.89 Nm, lowers windup, and enables higher body sizes compared to single or four beam couplings.

Its zero-backlash design and balanced configuration minimize vibration, enhancing performance and longevity in mechanical, fluid power, manufacturing, and laboratory equipment environments. The coupler supports angular misalignment up to 3°, parallel misalignment of 0.38 mm, and axial misalignment of 0.25 mm, accommodating minor shaft deviations during operation.

Additionally, it includes metric Nypatch anti-vibration hardware that prevents galling, maintains consistent screw holding power, and allows repeated installations with even screw seating. The coupler operates reliably within temperatures from -40°C to 107°C.

Manufactured in Ruland’s Marlborough, MA facility using exclusively North American sourced material, this coupler conforms to RoHS3 and REACH standards. It also meets DIN 912 12.9 specifications for screw quality, ensuring industrial-grade dependability.

Lightweight aluminium hub material offers low inertia and durability. Clamp style design for easy installation and secure connection. Supports continuous use at speeds up to 6000 rpm with minimal vibration. Suitable for use in industrial machinery, servo motor coupling, and power transmission systems.
