Set screw type
This is low cost and most common attachment method. However, since the screw point directly contacts the shaft, note that it may damage the shaft or make it difficult to remove the unit.
The bore is contracted by tightening force of the screw to clamp the shaft. Mounting and removal can be easily conducted, which does not damage the shaft.
Tight FitThe hub and sleeve are press-fit and can be used under zero backlash＊１. Since the sleeve's vibration absorption can raise the gain of a servomotor, this unit can achieve high responsive operation exceeding the Disk coupling.
＊1： For the torque used under zero backlash, please refer to dimensional table.
Tight Fit ApplicationsXY stage / Index table / Machine tool / Injection molding machine
Easy FitThis unit allows you to easily assemble and partition the hub and sleeve. It is possible to mount a hub on the shaft in advance and easily assemble the unit even in a location where the coupling is less-visible.
Easy Fit ApplicationsTransport device / Mixer / Ventilator / Pump / Dispenser
