Introduction ▼
Taperlock is a highly reliable and widely used mechanical locking device designed to securely fasten pulleys, sprockets, and couplings to shafts without the need for keyways or setscrews. Utilizing a tapered bushing system, Taperlock ensures a tight, backlash-free connection, minimizing vibration and preventing loosening under high torque or dynamic loads.
