💡 What is a jaw type flexible coupling used for in a motor drive system?

This handy device helps connect rotating shafts with tolerance for misalignment in a drive system.

• Absorbs minor angular misalignment and shaft runout
• Provides near-zero backlash at low torque due to tight fit
• Allows quick, clean installation between motor and drive hubs
