Ruland Aluminium Clamp Style Flexible Shaft Coupler 19.1 mm OD 4 mm Bore 22.9 mm Length PCMR19-4-4-A

Ruland PCMR19-4-4-A Aluminium Clamp Style Flexible Shaft Coupler is designed for demanding mechanical power transmission applications where high speed, precise alignment, and minimal maintenance are critical. The aluminium construction offers lightweight durability and corrosion resistance, ideal for industrial environments such as robotics, servo drives, pumps, fans, and measuring instruments.

This clamp style coupler uses a one-piece manufacturing method to eliminate mechanical joints, ensuring torsional rigidity and zero backlash operation. With a torque rating of 1.92 Nm and ability to operate at speeds up to 6000 rpm, it delivers reliable performance under dynamic loads.

It accommodates up to 3° angular misalignment, 0.2 mm parallel misalignment and 0.13 mm axial misalignment, providing flexibility in shaft alignment without compromising coupling integrity. Its four-beam design and moment of inertia of 0.731 x 10-6 kg/m² further contribute to smooth torque transmission.

Operating temperature ranges from -40°C to 107°C, making it suitable for varied industrial environments. Compliance with DIN 912 12.9, REACH, and RoHS3 standards guarantees material and manufacturing excellence. The clamp style fixing secures shafts with M2.5 socket head cap screws, ensuring a firm fit with 4 mm bore size on both ends.

Typical applications include use with encoders, stepper motors, robotics, servo systems, pumps, valves, and fans requiring precise and reliable connection. This coupler requires no lubrication and tolerates limited shaft misalignment, enhancing operational life and reducing maintenance efforts.
