Product Description
Ruland FSMR19-5-5-A is a high-quality Mechanical Power Transmission Coupler engineered for precision applications requiring flexible yet reliable torque transfer. The coupling features a 19.1 mm outer diameter and a precise 31.8 mm length, with matched 5 mm bores on both ends, enabling its use in coupling servo motors to lead screws with zero backlash.
Manufactured from 7075 aluminium bar stock, this coupler combines lightweight design with enhanced torque capacity through its six beam, dual three-spiral cut configuration. This design not only ensures superior torsional rigidity but also minimizes windup, enabling smooth operation at speeds up to 6000 revolutions per minute.
Its balanced design reduces vibration and supports various types of shaft misalignment, including angular misalignment up to 3 degrees, parallel misalignment of 0.2 mm, and axial misalignment of 0.13 mm. The bellows material, made from 7075-T651 extruded drawn aluminium, provides resilience and durability even at operating temperatures ranging from -40 degrees Celsius to 107 degrees Celsius.
This coupler is suitable for light duty power transmission tasks in industrial, manufacturing, automation, and laboratory equipment where precise servo motor connections are critical. Assembly hardware is metric with M4 screw size, ensuring secure and standardized fastening.
Made from high-strength 7075 aluminium alloy with lightweight and low inertia properties. Six beam coupling design with dual spiral cuts for enhanced torque and reduced windup. Zero-backlash operation at high rotational speeds up to 6000 rpm.
Supports angular, parallel, and axial shaft misalignments to accommodate installation variances. Operating temperature suitability from -40°C to 107°C for versatile environments. Complies with RoHS3, DIN 912 12.9, and REACH standards for safety and environmental requirements.
Ideal for coupling servo motors to lead screws in light industrial power transmission. Manufactured under strict proprietary processes ensuring consistent quality. Explore our comprehensive range of mechanical couplers and flexible couplings at EnvMart for your power transmission needs.
