12.7mm to 12.7mm Jaw Type Flexible Coupling D40-L66 - Aluminum Shaft Coupler for Motor and Drive Connections
✔️ Bore 12.7mm to 12.7mm, 66mm long, 40mm dia, aluminum
The D40-L66 is a jaw-type flexible coupling that connects motors to drive shafts in machines like CNC setups, robotics, and conveyors. Made from durable aluminum, it provides a strong, lightweight link with near zero backlash at low torque, smooth fit, and good vibration tolerance. It also offers electrical insulation to minimize stray currents in sensitive systems.
✅ Bore 12.7mm to 12.7mm; length 66mm; outer diameter 40mm; material aluminum
✅ Jaw-type design offers zero-backlash at low torque
✅ Easy fit with smooth assembly of hub and sleeve
✅ Electrical insulation reduces conduction across the joint
💡 What is a jaw-type flexible coupling and why choose it for motor drives? This handy piece helps connect motor shafts to driven shafts with tolerance for misalignment and vibration.
- Helps absorb angular and parallel misalignment for smoother motion
- Reduces backlash for precise positioning in low-torque systems
- Simple installation and quick replacement of the spider insert
- Electrical insulation helps prevent stray currents
