Ruland Flexible Clamp Coupler Bore 6 mm x 5 mm 19.1 mm OD 31.8 mm Length 6000 RPM Torque 2.94 Nm FCMR19-6-5-A

Ruland FCMR19-6-5-A is a high-quality flexible clamp coupler designed for mechanical power transmission systems requiring precise torque transfer and vibration resistance. Manufactured from a single piece of 7075-T651 extruded drawn aluminium bar, this coupler features a robust clamp style construction that provides zero backlash and reliable operation in servo motor to lead screw coupling and other light duty industrial applications.

The coupler has a 19.1 mm outer diameter with a length of 31.8 mm and accommodates bore sizes of 6 mm and 5 mm. It supports a maximum speed of 6000 rpm and a torque rating of 2.94 Nm, delivering efficient power transmission with low moment of inertia valued at 1.037 x 10-6 kg/m². Its design allows for angular misalignment up to 3°, parallel misalignment up to 0.2 mm, and axial misalignment up to 0.13 mm, ensuring adaptability to mechanical variations and reducing stress on connected components.

This product is engineered to withstand an operating temperature range from -40°C to 107°C, making it suitable for diverse industrial environments. It complies with DIN 912 12.9, REACH, and RoHS3 standards, demonstrating conformity to industry safety and environmental regulations. The inclusion of metric M3 screws with Nypatch® anti-vibration treatment maintains high holding power, prevents galling, and allows repeated screw installations, increasing maintenance convenience and reliability.

This flexible clamp coupler is ideal for industrial, laboratory, manufacturing, and automation sectors requiring robust shaft coupling solutions. Constructed from 7075-T651 extruded aluminium bar for strength and low inertia.

Clamp style delivers zero backlash performance with high holding power screws. Designed for bore sizes 6 mm and 5 mm, outer diameter 19.1 mm, length 31.8 mm. Maximum rated speed of 6000 rpm and torque capacity of 2.94 Nm.
