Ruland Aluminium Clamp Style Flexible Shaft Coupler 19.05 mm Outside Diameter 6.35 mm Bore Size 22.9 mm Length PCR12-4-4-A

Ruland PCR12-4-4-A is a high-performance aluminium flexible shaft coupler featuring a clamp style fixing mechanism. Engineered to accommodate higher speeds, increased misalignment, and limited lubrication conditions, this coupler excels where others might fail.

The one-piece torsionally rigid construction eliminates mechanical joints, ensuring zero backlash and enhanced reliability for demanding applications.

This coupler supports shaft bores of 6.35 mm on both ends with an outside diameter of 19.05 mm and a length of 22.9 mm, making it compact and lightweight due to its aluminium composition.

Rated for up to 6000 rpm and with a torque capacity of 67.8 Nm, it tolerates up to 3° of angular misalignment, 0.2 mm parallel misalignment, and 0.13 mm axial misalignment, permitting flexible integration into various mechanical systems.

Its operating temperature range from -40°C to 107°C allows usage in diverse environments without performance degradation. This coupler is manufactured under strict standards including REACH, RoHS3, and DIN 912 12.9 ensuring quality and compliance.

Typical industrial uses include encoder coupling, stepper motor drives, robotics systems, measuring instruments, servo systems, pumps, valves, and fans. The clamp style fixing provides a secure and easily maintainable shaft connection with reduced risk of slippage.

Constructed from durable aluminium material for lightweight and corrosion resistance. Features clamp style fixing for secure, backlash-free connection. Suitable for shaft bores of 6.35 mm diameter on both ends. Effective at speeds up to 6000 rpm with a torque rating of 67.8 Nm.

Allows up to 3° angular misalignment and minimal parallel and axial misalignments. Operates reliably within a temperature range of -40°C to 107°C. Manufactured as a single piece eliminating mechanical joints and failure points.

Complies with REACH, RoHS3, and DIN 912 12.9 standards. Ideal for use in robotics, stepper motors, servo systems, encoders, pumps, and fans. Explore EnvMart’s wide selection of mechanical power transmission components for robust and precise coupling solutions.
