💡 Why are jaw-type flexible couplings commonly used in CNC and servo drive systems?
They balance precision with flexibility in compact drive layouts.

• Tight fit design helps keep backlash near zero under normal loads

• Elastomer insert absorbs vibration and shock from motor starts

• Accepts shaft misalignment without stressing bearings

• Handy for servo motors stepper motors and precision automation setups
