Product Description
Ruland PSMR25-6-6-A aluminium flexible screw style coupler is engineered for demanding mechanical power transmission where high speed, misalignment, and durability are critical. Manufactured as a one-piece component, this coupling eliminates mechanical joints and potential failure points common in multi-part couplers.
The coupling has an outer diameter of 25.4 mm, bore sizes of 6 mm on both shaft sides, and a length of 31.8 mm. It features 4 flexible beams that permit torsional rigidity along with up to 3 degrees of angular misalignment, 0.38 mm parallel misalignment, and 0.25 mm axial misalignment. These characteristics ensure excellent performance in dynamic systems.
Constructed from aluminium, it offers corrosion resistance, lightweight design, and high operating temperatures capability up to 107°C. The coupling secures shafts using M4 screws in a screw-style fixing mechanism, promoting ease of assembly and reliability.
Typical applications include encoders, stepper motors, robotics, measuring instruments, servo systems, pumps, valves, and fans across various industrial, laboratory, and manufacturing environments.
Lightweight aluminium construction offers corrosion resistance. Flexible beams allow precise torque transmission with minimal backlash. Screw-style fixing ensures a secure shaft connection. Designed for high speed operation up to 6000 rpm.
Handles torque ratings up to 4.07 Nm reliably. Tolerates angular, parallel, and axial misalignments. Wide operating temperature range from -40°C to 107°C. Ideal for robotics, pump systems, and servo motor applications. This coupler complies with DIN 912 12.9, REACH, and RoHS3 standards, guaranteeing quality and environmental compliance.
