Good but tight
Set screws were very tight, needed good leverage. Works great though.
Description
This spider coupling connects servo motors to leadscrews or encoders to transmit high torque while accommodating misalignment. Constructed from aluminum alloy, the star-type elastic design absorbs vibration and reduces mechanical stress during operation. The flexible element allows for angular, parallel, and axial deviations to protect connected components. Regularly inspect the elastic spider insert for wear and replace it if signs of degradation appear to maintain optimal performance.
