Ruland Aluminium Flexible Shaft Coupler 9.5 mm OD, 3 mm Bore, 14.3 mm Length, 6000 rpm, PSMR10-3-3-A

Ruland PSMR10-3-3-A Aluminium Flexible Shaft Coupler is expertly engineered for mechanical power transmission systems requiring high speed, precise alignment and reliable torque transfer. With an outside diameter of 9.5 mm, both bore A and bore B at 3 mm, and a total length of 14.3 mm, this coupler is ideal for compact mechanisms and robotics.

The shaft coupler is manufactured from premium aluminium, offering excellent strength-to-weight ratio and minimal moment of inertia at 0.029 x 10-6 kg/m². Its design allows for operating speeds up to 6000 rpm and a torque rating of 0.62 Nm, making it suitable for stepper motors, servo systems, measuring instruments, encoders, pumps, fans, and valves.

Capable of handling up to 3° angular misalignment, 0.2 mm parallel and 0.13 mm axial misalignment, the PSMR10-3-3-A provides flexibility while maintaining performance and constant velocity due to its torsionally rigid, one-piece construction. No lubrication is required, simplifying maintenance in laboratory, industrial, and factory environments.

Constructed from high-quality aluminium for durability and reduced inertia. Features a 9.5 mm outside diameter and dual 3 mm bores. Supports speeds up to 6000 rpm and torque transfer rated at 0.62 Nm. Accommodates angular, parallel, and axial misalignments in precision applications.

Clamp-style fixing with M5 socket head cap screws ensures secure installation. Compliant with DIN 912 12.9, REACH, and RoHS3 standards for quality and environmental responsibility. Operating temperature range covers -40°C to 107°C for versatile usage.

Typically fits automation, robotics, process instrumentation, and industrial machinery. The coupler is backed by strict quality standards and is made in the United States. It is designed for high or low speed operation, with reversible motion and zero backlash.

Common applications include integration into robotic actuators, precision stepper motors, laboratory instruments, and automated assembly systems where motor-to-shaft coupling reliability is paramount.
