12mm to 20mm Jaw Type Flexible Coupling D40-L66 - Aluminum Shaft Coupler for Motor and Drive Connections

This compact jaw-type flexible coupling connects a motor shaft to a drive system, ideal for CNC machines, 3D printers, conveyors, and robotics where space is tight and precise torque transfer is needed.

✅ Bore 12mm and 20mm options for a tight fit
✅ Outer diameter 40mm, length 66mm, D40 housing
✅ Aluminum alloy construction keeps weight down and resists corrosion
✅ Tight-fit design reduces backlash at low torque
✅ Electrical insulation included in the design
✅ Spider insert color varies by ex-stock

💡 What is a jaw-type flexible coupling used for in drive systems? This handy device links motor and driven shafts, reducing vibration and accommodating minor misalignment.

• Precise torque transfer with minimal backlash in a compact package
• Handles angular misalignment and small shaft offset
• Lightweight aluminum body simplifies mounting and serviceability
