Product Description

Ruland PCR12-6MM-1/4"-A Aluminium Flexible Coupler features a 19.1 mm outside diameter and 6.35 mm bore size A with 152.4 mm bore size B, designed specifically for mechanical power transmission where higher speeds and greater misalignment occur.

This clamp style coupler allows precise torque transfer of 1.58 Nm and supports speeds up to 6000 rpm. The aluminium construction ensures lightweight durability suitable for demanding industrial, laboratory, robotics, and automation applications.

Its torsionally rigid, one-piece design eliminates mechanical joints and failure points while providing zero backlash during operation. The coupling accommodates up to 3° angular misalignment, 0.2 mm parallel misalignment, and 0.13 mm axial misalignment, increasing reliability in fluctuating mechanical environments.

The coupler's robust temperature range from -40°C to 107°C makes it suitable for a variety of environments without lubrication needs, enhancing maintenance ease and operational lifespan. Typical use cases encompass encoders, stepper motors, robotics, measuring instruments, servo systems, pumps, valves, and fans in industrial, manufacturing, and automation sectors.

This product features clamp style fixing using one socket head cap screw per shaft for secure clamping. The one-piece aluminium construction ensures high torque capacity and eliminates mechanical failure points. Its design supports reversible and high or low-speed operation without lubrication requirements.

Compliant with DIN 912 12.9, RoHS3, and REACH standards for assured quality and compliance. Manufactured in the United States, the coupler meets rigorous industrial standards.
