Flexible Shaft Couplings are mechanical connection components designed to join two rotating shafts at their ends to transmit torque while accommodating angular, parallel, or axial shaft misalignments. By dampening dynamic torque spikes and isolating mechanical vibration between motor shafts and driven loads, these couplings reduce stress on bearings, shafts, and motor seals, ensuring smooth power transfer. Key hardware features typically include high-strength aluminum or stainless steel hubs, flexible polyurethane elastomeric spiders, disc packs, or bellows elements, keyway slots, and integrated clamping bolts.
