Product Description
Ruland MOST19-6-A aluminium set screw style flexible coupler is engineered for precise mechanical power transmission, featuring a 19.1 mm outside diameter, 6 mm bore diameter without keyway, and 9.7 mm hub length.
This flexible Oldham coupling design allows for slight axial, angular, and parallel misalignments, making it suitable for light industrial, motion control, and automation applications such as stepper and servo motor drives. The set screw securing mechanism ensures a secure fit to the shaft, with anodised aluminium providing corrosion resistance and lightweight structural integrity.
Its maximum operational speed is 4500 rpm, which supports higher-speed applications while offering torque overload protection through a three-piece design consisting of two hubs and a torque disc. The centre disc is typically replaceable and designed to break cleanly to safeguard the system during torque overloads.
Ruland flexible couplers comply with RoHS and REACH environmental standards. The coupling is finished with a bore that has no keyway, enhancing the fitment possibilities and reducing shaft damage risk.
Manufactured from anodised aluminium to ensure lightweight and strength. Set screw style securing for robust shaft coupling. Supports up to 4500 rpm maximum speed. Tolerates angular misalignment of 0.5°, parallel misalignment of 0.2 mm, and axial misalignment of 0.1 mm.
Designed for light industrial and motion control applications. Compliant with RoHS and REACH standards for environmental safety. Requires 2 hubs and 1 torque disc for complete assembly.
These mechanical couplers are essential for industrial machinery requiring flexible coupling solutions that protect equipment from torque overload and misalignment induced stress. They are widely used in manufacturing, automation, robotics, and other precision equipment setups.
