Product Description
Ruland PCMR19-5-5-A Aluminium Flexible Beam Coupler delivers robust performance for mechanical power transmission systems requiring precise connection and flexible operation. With a 19.1 mm outer diameter, 5 mm bore on both sides, and a compact 22.9 mm length, this coupler is engineered for demanding applications in industrial automation, robotics, measurement systems, and servo drives.
High-quality aluminium construction offers strength and corrosion resistance, enabling reliable operation in harsh environments. Clamp style bean coupler eliminates backlash and guarantees consistent torque transmission, critical for high-precision machinery.
Accommodates multiple misalignment types: up to 3° angular, 0.2 mm parallel, and 0.13 mm axial, reducing stress and extending component lifespan. Rated for a maximum speed of 6000 rpm, suitable for both high and low speed operations, and reversible drive scenarios.
Moment of inertia: 0.731 x 10⁻6 kg/m² ensures rapid response and minimal energy loss in motion control. Operational temperature range from -40°C to 107°C enables versatility in applications demanding extended environmental durability.
No lubrication required due to the torsionally rigid, one-piece construction with four beams; maintenance-free operation for critical systems. Complies with DIN 912 12.9, REACH, and RoHS3 standards, ensuring suitability for regulated industrial environments.
The coupler is commonly used for connecting shafts in encoders, stepper motors, robots, measuring instruments, and servo systems, facilitating constant velocity transmission. Its clamp style socket head cap screw fixings provide secure installation while supporting high torque and zero backlash.
Industrial use cases include mechanical power transmission in manufacturing facilities, process automation lines, HVAC systems, scientific instrumentation, and water treatment equipment. It is also ideal for applications demanding limited lubrication, high misalignment capability, and consistent velocity profile.
