Ruland disc couplings
The disc couplings strengths are in its simple assembly and few moving parts which reduce the risk for coupling failure and backlash. The disc coupling utilises thin stainless steel disc springs that allow for a substantial amount of shaft misalignment while remaining rigid under torsional loads. Disc couplings feature a balanced design allowing for smooth operation at speeds up to 10,000 rpm. Screws are used to mount the disc springs to maintain constant zero-backlash performance.
