This D40-L66 jaw-type flexible coupling is a lightweight aluminum shaft coupler designed to connect motors to drives with minimal backlash. It's ideal for compact machinery, robotics, CNC setups and conveyors where precise alignment and damping of vibrations matter.

✅ Bore sizes: 16 mm and 1/2 in bore
✅ Material: Aluminum body for light weight
✅ Length: 66 mm, diameter 40 mm
✅ Zero-backlash at low torque for precise transmission
✅ Easy hub and sleeve assembly with electrical insulation

💡 What is a jaw-type flexible coupling used for?

It's handy for connecting rotating shafts while tolerating minor misalignment and damping vibration in drive systems.

- Hand-friendly for motor-to-drive connections in compact machinery
- Absorbs small angular and parallel misalignment
- Reduces transmitted vibration in conveyors and robotics
