Ruland Flexible Coupler 15.9 mm OD 5 mm Bore 20.3 mm Length Clamp Style Aluminium Bellows PCMR16-5-3-A

Ruland PCMR16-5-3-A is a flexible coupling specifically designed for mechanical power transmission applications requiring high precision and reliability. This four beam clamp style coupler features two sets of spiral cuts machined from a single piece of 7075 aluminium, providing improved torque capacity, reduced windup, and enhanced vibration balancing for high-speed rotation up to 6000 rpm.

The coupling has an outside diameter of 15.9 mm, bore sizes of 5 mm and 3 mm respectively, and an overall length of 20.3 mm. The clamp style design allows secure and easy installation with metric M2 screws. Its balanced design ensures zero backlash and reduced vibration, important features for encoding and positioning systems demanding accuracy.

Constructed from 7075-T651 extruded drawn aluminium bar sourced from North American mills and manufactured under stringent controls in Marlborough, MA, this coupler provides lightweight and low inertia performance with a torque rating of 1.36 Nm. It accommodates angular misalignment up to 3 degrees, parallel misalignment up to 0.2 mm, and axial misalignment up to 0.13 mm.

This coupler operates reliably within a temperature range of -40°C to 107°C, ensuring suitability for various industrial environments. It meets DIN 912 12.9, REACH, and RoHS3 compliance requirements, guaranteeing quality and environmental safety.
