💡 What is a 19mm to 18mm jaw-type flexible coupling used for in motor and drive systems?

Handy explanation: it transmits torque while accommodating small misalignment and damping twisting vibration.

- Handily supports minor angular and parallel misalignment while transferring torque - Reduces backlash and quiets vibrations in compact drive trains - Provides electrical insulation between shafts for safety - Easy to install on 19mm to 18mm shafts in tight spaces
