Ruland Aluminium Clamp Style Flexible Shaft Coupler 25.4 mm OD 6 mm Bore 31.8 mm Length PCMR25-6-6-A

Ruland PCMR25-6-6-A Aluminium Clamp Style Flexible Shaft Coupler features a 25.4 mm outside diameter, 6 mm bore size on both shafts, and a length of 31.8 mm. This aluminium coupling is engineered for high-speed mechanical power transmission with maximum operating speeds of up to 6000 rpm and a torque rating of 4.07 Nm, making it suitable for precise and demanding industrial applications.

Its clamp fixing style uses one socket head cap screw per shaft, providing a secure and reliable connection. The one-piece machinined construction ensures torsional rigidity with zero backlash, which is critical for maintaining precise motion transfer and minimizing wear.

Designed to tolerate misalignments, the coupling supports angular misalignment up to 3°, parallel misalignment of 0.38 mm, and axial misalignment of 0.25 mm, allowing for slight shaft misalignment without damaging system components or affecting performance.

The aluminium construction provides excellent strength-to-weight ratio and resistance to temperature variations, with a minimum operating temperature of -40°C and a maximum of 107°C, making it suitable for a wide range of industrial and laboratory environments.

This coupling is ideal for use with encoders, stepper motors, robotics, servo systems, pumps, valves, and fans where precise torque transmission and flexibility are required. Its compliance with REACH, RoHS3, and DIN 912 12.9 standards further ensures quality and safety.

Durable aluminium material offers lightweight strength and corrosion resistance. Clamp style fixing for easy installation and strong shaft attachment. High torque capacity with zero backlash for precise motion control. Tolerant to angular, parallel, and axial misalignments to protect connected components.

Wide operating temperature range suitable for various industrial conditions. One-piece construction eliminates mechanical joints to reduce failure points. Suitable for robotics, servo systems, measurement instruments, and fluid power applications.

Designed to maintain performance at speeds up to 6000 rpm.

This Ruland coupling provides a reliable and durable solution for mechanical power transmission needs in industrial and manufacturing sectors. Explore more mechanical power transmission products on EnvMart for your industrial applications.
