0.5 Inch to 20mm Jaw Type Flexible Coupling D40-L66 - Aluminum Shaft Coupler for Motor and Drive Connections

Aluminum Jaw-Type Flexible Coupling D40-L66: 0.5in-20mm
✔️ 0.5in to 20mm bore, 66mm length, 40mm OD, single unit

This D40-L66 jaw type flexible coupling is designed to join two shafts with minimal backlash and smooth torque transfer, typically used in servo and motor drive systems.

✅ Bore1: 0.5in (12.7mm); Bore2: 20mm (0.79in); Length: 66mm (2.60in); OD: 40mm (1.57in)
✅ Material: Aluminum; Electrical insulation; Jaw-type spider design
✅ Backlash: near zero at low torque; supports slight misalignment
✅ Easy fit: simple hub and sleeve assembly for quick installation

💡 What is a typical use case for jaw-type flexible couplings?

Jaw-type couplings provide a handy link between motor and driven shafts, tolerating small misalignment while reducing vibration and wear.

- handy for alignment tolerance and smooth torque transfer - reduces backlash in light duty drive systems - ideal for servo motors, stepper drives, and small gearboxes - lightweight aluminum design resists corrosion in lift and automation setups
