Coupling Selection Guide
Collect motor power and speed or transmitted torque, both shaft sizes and keyways, application description, start/stop or shock conditions, environmental limits and installation space. Compare the candidate model against both torque and bore capacity, then confirm the final duty and drawing before production.
Installation Instruction
Prepare clean parts, mount the hubs to the approved positions, align the shafts, fit the flexible element without forcing it, verify hub spacing and fastening, and inspect after commissioning. Exact tolerances and fastening values should follow the approved drawing or project specification.
