• Can be easily attached to and removed from the shaft with a single spanner.
• No damage to shaft and shaft holes. When attaching to the shaft, it enters smoothly, and tightens firmly using the taper by tightening the tightening bolt, so there is no slight wear at the fitting part during use, and the life of the shaft is extended.
• Since shaft holes and key grooves corresponding to the standard shaft diameter are machined on the bushing, machining is not required during use.
• Position change of rotating body such as pulley on shaft is smooth, and centering can be easily performed.
