Ruland Aluminium Clamp Style Flexible Shaft Coupler 25.4 mm Outside Diameter 6 mm Bore 38.1 mm Length FCMR25-6-6-A

Ruland FCMR25-6-6-A Aluminium Clamp Style Flexible Shaft Coupler with a 25.4 mm outside diameter, 6 mm bore sizes (A and B), and 38.1 mm length is engineered for precise mechanical power transmission in demanding industrial and robotics applications.

This coupling is manufactured as a single piece of aluminium to provide torsional rigidity and eliminate mechanical joints, thereby increasing durability and reducing failure points in high-speed and misalignment-prone environments.

Designed to handle maximum speeds of up to 6000 rpm and torque ratings of 3.95 Nm, it supports angular misalignment up to 3°, parallel misalignment up to 0.38 mm, and axial misalignment up to 0.25 mm. Its light aluminium material offers low moment of inertia, measured at 4.12 x 10⁻⁶ kg/m², which benefits dynamic performance.

The clamp style fixing employs a socket head cap screw (M4 size), providing a reliable, backlash-free connection ideal for robotics, servo motors, stepper motors, encoders, pumps, valves, and fan assemblies, especially where high precision and zero backlash are needed.

Operating across a wide temperature range from -40°C to 107°C, this coupling meets stringent industry standards including DIN 912 12.9, REACH, and RoHS, certifying material and environmental compliance required in industrial and manufacturing environments.

Its application scope covers fluid power and mechanical power transmission scenarios demanding flexibility under misalignment stresses while maintaining performance and reliability without the need for lubrication.

Clamp style fixing provides secure, backlash-free torque transmission. Durable aluminium construction with one-piece design improves strength and eliminates mechanical joint failure. Supports high speed up to 6000 rpm and torque rating of 3.95 Nm.

Accommodates angular, parallel, and axial misalignment within specified limits. Operates efficiently within temperature range from -40°C to 107°C. Meets DIN 912 12.9, REACH, and RoHS standards ensuring quality and safety.

Ideal for industrial robotics, servo systems, pumps, valves, and fans. No lubrication required, reducing maintenance efforts and downtime. Light moment of inertia aids dynamic response in precision machinery. Explore a comprehensive range of Ruland mechanical power transmission products at EnvMart for reliable industrial applications.
