💡 What is a jaw-type flexible coupling used for in precision machinery and servo systems? These couplings transfer torque while accommodating misalignment and end-play. - They reduce shaft loads and vibration for smoother operation. - They handle eccentricity, angular misalignment, and end-play with bellows design. - They provide electrical insulation and noise suppression in mixed environments. - They are ideal for compact automation setups requiring precise torque transfer. In short, it’s handy for compact automation, robotics, CNC and servo-driven systems that demand smooth, backlash-minimized torque transfer.
