0.625 Inch to 15mm Jaw Type Flexible Coupling D40-L66 - Aluminum Shaft Coupler for Motor and Drive Connections

0.625in to 15mm Jaw-Type Aluminum Flexible Coupling D40-L66
✔️ 0.625 in to 15 mm bore, 66 mm length, 40 mm dia, aluminum

The D40-L66 jaw-type flexible coupling is a compact aluminum shaft coupler designed to connect motors and drive systems. It handles minor angular deviation, eccentricity, and twisting vibration while maintaining a tight, backlash-free fit at low torque. This single-unit, 1-piece package is ideal for hobby CNC machines, 3D printers, and automation setups where reliable power transfer is needed.

✅ Bore1: 0.625 in (15.88 mm); Bore2: 15 mm; Length: 66 mm (2.60 in)
✅ Outer diameter: 40 mm (1.57 in); Material: Aluminum
✅ Jaw-type design with zero backlash at low torque; Electrical insulation
✅ Package: 1 piece per order (single-unit)

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

Jaw-type couplings help connect two shafts while absorbing small misalignment and vibration.
- Handy for improving life of motors and bearings by reducing stress
- Improves smooth speed transfer by limiting backlash and wobble
- Lightweight aluminum body makes setup easy in space-limited apps
