✅ Outer diameter: 40 mm
✅ Material: Aluminum
✅ Backlash-free at low torque; tight fit for smooth transmission
✅ Electrical insulation between shafts
✅ Pack: 1 (single unit)

💡 What is the best way to pick a jaw-type flexible coupling for a motor and drive setup?

Choosing a coupling involves matching shaft sizes, misalignment tolerance, and torque to prevent backlash.

• Low-backlash torque transmission supports precise positioning
• Accommodates minor angular misalignment and shaft runout
• Aluminum housing keeps weight down and adds rigidity
• Electrical insulation helps protect electronics
