12mm to 12.7mm Jaw Type Flexible Coupling D40-L66 - Aluminum Shaft Coupler for Motor and Drive Connections
✔️ 12 mm to 12.7 mm bore, 66 mm length, 40 mm OD, aluminum, zero-backlash
The D40-L66 jaw-type flexible coupling is a lightweight aluminum shaft coupler designed to connect motors and drives. It's a single-pack unit ideal for compact setups where minimal backlash and smooth torque transfer are key. It’s commonly used in CNC machines, robotics, and automation projects to accommodate slight misalignment and shaft twisting without adding vibration.
✅ Bore1 12 mm; Bore2 12.7 mm; Length 66 mm; OD 40 mm; Aluminum
✅ Jaw-type flexible coupling; zero-backlash at low torque
✅ Easy hub and sleeve assembly; good misalignment tolerance
✅ Electrical insulation; insert spider color varies
💡 What is a handy choice for connecting motors to drives with minimal backlash?
Answer: Jaw-type aluminum couplings provide precise fit and damping for small misalignment.
- Tight, zero-backlash torque transmission at low loads
- Handles angular misalignment and shaft twist effectively
- Easy installation with standard bore options
