18mm to 10mm Jaw Type Flexible Coupling D40-L66 - Aluminum Shaft Coupler for Motor and Drive Connections

D40-L66 Aluminum Jaw-Type Coupling 18mm-10mm bore, single unit
✔️ 18mm-10mm bore, 66mm length, 40mm aluminum body for motor drives

The D40-L66 jaw-type flexible coupling is a compact aluminum shaft coupler designed to join motor and drive shafts. It’s commonly used in robotics, CNC machines, and automation setups where space is tight and easy assembly matters.

✅ Bore sizes: 18mm and 10mm for standard shafts
✅ Jaw-type design with zero backlash at low torque
✅ Overall length 66mm and body diameter 40mm, aluminum
✅ Electrical insulation and light weight for easy mounting
✅ Simple fit and smooth hub-to-sleeve assembly

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

It’s handy for joining two shafts while tolerating minor misalignment and damping vibrations.

• Backlash-free torque transfer at low to moderate speeds
• Accommodates angular misalignment and small shaft offset
• Lightweight aluminum body eases installation in tight spaces
• Ideal for compact automation, robotics, and small conveyors
