Locking assemblies are linkers used between shafts and pulleys, which can replace the single keys and splines. They can transmit torque through a set of tightening screws with high strength, and make the required clamping force either between the inner rings and shafts or between the outer rings and hubs. Easy assembling and disassembling.They have a good inter changeablity. The screws are with high strength. Their main material is superior steel. After machining, they will have a smooth and beautiful surface, a long lifetime, and high strength.
