Ruland Aluminium Flexible Screw Style Coupler 19.1 mm OD 5 mm Bore, 22.9 mm Length PSMR19-5-5-A

Ruland PSMR19-5-5-A is a high-quality aluminium flexible screw style coupler specifically engineered for mechanical power transmission applications requiring precise torque transfer and misalignment compensation. Designed as a one-piece construction, this coupler eliminates mechanical joints that can introduce failure points, thus ensuring durability and reliability in demanding industrial environments.

The coupler features a 19.1 mm outside diameter and measures 22.9 mm in length, with bore sizes of 5 mm on both sides, making it suitable for shafts with these dimensions. It supports a maximum rotational speed of up to 6000 rpm and has a torque capacity of 1.92 Nm, fitting applications like encoders, stepper motors, robotics, and servo systems.

This flexible coupling allows angular misalignment up to 3°, parallel misalignment up to 0.2 mm, and axial misalignment up to 0.13 mm, accommodating slight misalignments without compromising performance. It operates efficiently in temperature ranges from -40°C to +107°C, addressing diverse industrial operating conditions.

Compliant with RoHS3, REACH, and DIN 912 12.9 standards, the product meets environmental and mechanical quality criteria. The screw style fixing uses M4 size screws, with four beams providing constant velocity with zero backlash, promoting smooth and precise torque transmission.

Durable aluminium construction offers lightweight strength and corrosion resistance. One-piece design reduces failure points and maintenance needs. High maximum speed rating suitable for dynamic applications. Torque rating supports precision motion control systems.

Allows for multiple misalignment types to enhance shaft coupling longevity. Wide operating temperature range accommodates various industrial settings. RoHS3, REACH, and DIN compliance ensure adherence to industry standards.

Perfect for robotics, pumps, valves, fans, encoders, and stepper motors.

This coupling is manufactured in the United States and provides a reliable solution for precise mechanical motion transmission in industrial, laboratory, and automation sectors. It delivers high performance for applications requiring accurate shaft alignment and torque fidelity.
