0.5 Inch to 18mm Jaw Type Flexible Coupling D40-L66 - Aluminum Shaft Coupler for Motor and Drive Connections

These jaw-type flexible couplings connect motors to drives, absorbing small misalignments while transmitting torque with minimal backlash. They’re commonly used in CNC machines, 3D printers, robotics, and other compact automation setups.

✅ Bore range: 0.5 in to 18 mm (12.7 mm to 18 mm)
✅ Outer diameter: 40 mm (1.57 in), length: 66 mm (2.60 in)
✅ Material: Aluminum housing for light weight and rigidity
✅ Electrical insulation between hub and sleeve reduces interference
