Ruland 38.1 mm Outer Diameter 15 mm Bore Six Beam Clamp Style Flexible Coupler 57.2 mm Length FCMR38-15-15-SS

Ruland FCMR38-15-15-SS is a precision-engineered six beam flexible coupler designed for reliable mechanical power transmission in industrial applications. It features a 38.1 mm outer diameter with 15 mm bores on both ends and a total length of 57.2 mm. Manufactured from high-grade 303 stainless steel bar stock sourced exclusively from North American mills, this coupler provides exceptional torque capacity and corrosion resistance.

Its clamp style hub design utilizes two sets of three spiral cuts, delivering increased torque, lower windup, and an enlarged body compared to single or four beam designs. This design enables zero-backlash performance and balanced operation, reducing vibrations even at high rotational speeds up to 6000 RPM.

The coupler supports misalignment handling with an angular tolerance of 3°, parallel offset up to 0.76 mm, and axial displacement of 0.38 mm. Operating temperature ranges from -40°C minimum to 176°C maximum make it suitable for diverse industrial environments, including servo motor to lead screw connections in light duty power transmission tasks.

Ruland supplies these couplings with Nypatch® anti-vibration hardware that ensures consistent screw torque, prevents galling, and maintains high clamping force through repeated installations. The hardware uses metric M6 screws compliant with DIN 912 12.9 standards.

This coupling adheres to REACH and RoHS3 standards, reinforcing its compliance for contemporary industrial applications. Its bellows are fabricated from 7075-T651 extruded drawn aluminium bar, combining strength and flexibility.

Applications include automation, robotics, manufacturing equipment, and fluid power transmission requiring precise, backlash-free shaft connections.

Set in the Industrial Supplies category under Mechanical Power Transmission Couplers, this product is a dependable component for designers and maintenance professionals demanding quality and longevity.
