This is a jaw type flexible coupling.
This superior high torque transmission is the most appropriate for the spindle of a machine tool.
Excellent flexibility allows eccentricity, and angular misalignment and vibration to be accepted.
It has electrical insulation. Resistance value: not less than 2 MΩ.
There are four types of sleeve hardness. Please select desirable units according to usage conditions including torque and misalignment.
Since the sleeve's vibration absorption can raise the gain of a servomotor, tight fit can achieve high responsive operation exceeding the Disk coupling.
Easy fit allows you to assemble and partition the hub and sleeve smoothly.
This allows you to reduce the time of assembling the unit and maintenance.
