Sturdy
Holds torque well under load. Easy to install on the servo motor shaft.
Description
This elastic star-type shaft coupler connects servo motors to ball screws or CNC lathe spindles to transmit torque while compensating for misalignment. Constructed from 7075 aluminum alloy, the component features an H6 precision fit and a flexible star element designed to absorb vibration and shock loads during high-torque operation. Regularly inspect the elastic insert for wear and replace it if signs of deformation or cracking appear to maintain optimal coupling performance.
