Product Description

Ruland PSR16-6-6-A Aluminium Flexible Shaft Coupler features a 25 mm outside diameter and 9.53 mm bore sizes on both ends with a length of 31.8 mm. It is designed for applications requiring high precision and reliable power transmission including industrial robotics, stepper motors, encoders, pumps, valves, and fans.

This coupling excels where higher speeds, greater misalignments, and limited lubrication would otherwise exceed the performance of other couplers. Its one-piece torsionally rigid aluminium construction eliminates mechanical joints and potential failure points, ensuring durable, backlash-free operation.

With a maximum speed rating of 6000 rpm and torque capacity of 25.8 Nm, it accommodates angular misalignment up to 3°, parallel misalignment of 0.38 mm, and axial misalignment of 0.25 mm, allowing reliable power transfer even with shaft misalignments. Operating temperature range is from -40°C to 107°C.

The PSR16-6-6-A features a screw style fixing with four beams and uses M4 DIN 912 12.9 screws. It is RoHS3 and REACH compliant, confirming environmental and material safety standards. Ideal for industrial, laboratory, manufacturing, and robotics applications.

Constructed from lightweight aluminium for balance of strength and weight. Designed for high-speed operation up to 6000 rpm. Capable of handling torque demands up to 25.8 Nm. Zero backlash performance with screw-style fixing and four beams.

Wide operating temperature range from -40°C to 107°C. Manufactured as single piece to minimize failure risk. Suits precision applications such as servo motors and encoders. Complies with industry standards including DIN 912 12.9, REACH, and RoHS3.

This flexible shaft coupling provides reliable, torsionally rigid, backlash-free mechanical power transmission. Its robust design and high-speed capability make it suitable for demanding engineering and industrial systems.
