💡 What is a jaw-type flexible coupling used for in precision machinery? These couplings transmit motion between shafts while absorbing misalignment and vibration. - Absorbs eccentricity and angular misalignment with a bellows-style jaw - Stainless steel construction resists corrosion in demanding environments - Works with small shaft diameters, 3 to 4.5 mm bore range - Zero-backlash at low torque helps maintain precise positioning in servo and CNC systems This handy coupling helps improve motion accuracy and reduce wear in compact drive trains.
