Ruland Aluminium Flexible Clamp Style Coupler 25.4 mm OD 10 mm Bore Size A 8 mm Bore Size B 31.8 mm Length PCMR25-10-8-A

The Ruland PCMR25-10-8-A Aluminium Flexible Clamp Style Coupler is engineered for mechanical power transmission requiring high-speed and precise shaft connections. Manufactured as a one-piece aluminium construction, the coupling delivers torsional rigidity while eliminating mechanical joints that could fail under stress.

With an outside diameter of 25.4 mm and a length of 31.8 mm, this model features dual bore sizes: 10 mm for bore A and 8 mm for bore B, providing versatility for different shaft dimensions. The clamp style design employs one socket head cap screw per shaft, enabling quick assembly with zero backlash for enhanced positional accuracy.

It operates effectively up to a maximum speed of 6000 RPM and supports a maximum torque rating of 3.39 Nm. The coupling is capable of absorbing up to 3 degrees of angular misalignment, 0.38 mm parallel misalignment, and 0.25 mm axial misalignment, making it suitable for demanding applications in robotics, stepper motors, servo systems, pumps, valves, fans, and encoders.

Constructed from lightweight aluminium, the coupling withstands operating temperatures ranging from minus 40 degrees Celsius to 107 degrees Celsius and requires no lubrication, ensuring maintenance-free use in industrial or laboratory environments.

This product complies with REACH, DIN 912 12.9, and RoHS3 standards, assuring environmental and safety compatibility. The moment of inertia is rated at 9.275 x 10⁻⁶ kg/m², supporting reliable torsional performance during operation.

The coupling's compact, clamp style design facilitates installation and reduces potential failure points. Its flexible beam design allows for misalignment absorption without compromising performance. The aluminium construction ensures corrosion resistance and strength with a lightweight profile.

Suitable for rapid, reversible, high-speed rotation applications. Ideal for precise motion control in mechanical power transmission systems including robotics and stepper motor assemblies.

Manufactured in the United States, this product ensures high quality and durability for industrial power transmission applications. Explore the category for additional Flexible Coupler options from Ruland and other high-quality brands at EnvMart.
