Product Description

Ruland FCMR25-12-12-A flexible coupler is designed for precise mechanical power transmission where high reliability and reduced backlash are essential. Machined from a single piece of lightweight 7075-T651 extruded drawn aluminium bar, this clamp style coupler features a 12 mm bore on both sides, 25 mm outside diameter, and a length of 38.1 mm. Its robust construction allows it to withstand torque up to 2.82 Nm and operate at speeds up to 6000 RPM while effectively compensating for angular, parallel, and axial misalignments.

This coupler is ideal for applications including servo motor to lead screw connections, light-duty power transmission, and situations demanding precision alignment and vibration reduction. The inclusion of M4 screws adhering to DIN 912 12.9 and RoHS3 compliance ensures high holding power, anti-vibration performance, and environmental safety. Its operating temperature range from -40°C to 107°C supports deployment in varied industrial, manufacturing, and automation environments.

Lightweight aluminium hub reduces moment of inertia and facilitates smooth rotation. Clamp style design guarantees a secure and adjustable connection. Balanced design minimizes vibration for high-speed applications up to 6000 RPM.

Suitable for mechanical, laboratory, HVAC, and manufacturing uses requiring flexible couplings. Compliant with REACH and RoHS3 for regulatory adherence. M4 metric screws with Nypatch anti-vibration hardware maintain consistent screw installation torque and prevent galling.

Manufactured under strict controls to ensure quality and performance reliability.

Ruland couplers are trusted components in power transmission systems, enabling efficient torque transfer and alignment compensation in industrial machinery.
