17mm to 22mm Jaw Type Flexible Coupling D40-L66 - Aluminum Shaft Coupler for Motor and Drive Connections

Jaw-Type Aluminum Flexible Coupling D40-L66, 17-22mm Bore
✔️ Bore 17-22mm, length 66mm, aluminum hub & sleeve, 1 pc

This jaw-type flexible coupling connects 17mm to 22mm shafts, delivering smooth torque transfer with zero backlash for small motors and drive assemblies. It’s a handy choice for compact CNCs, stepper motor setups, and other lightweight drive systems where precise alignment and a low-profile design matter.

✅ Jaw-type design with tight fit enables zero-backlash at low torque
✅ 40mm diameter, 66mm length, aluminum construction for light weight
✅ Accepts eccentricity, angular misalignment, and twisting vibration
✅ Electrical insulation and easy hub/sleeve assembly; 1 pc pack

💡 What is a jaw-type flexible coupling used for in small motor and drive systems? Handy for keeping shafts aligned while absorbing minor misalignment and vibration.

• low-backlash torque transfer for precise operation
• absorbs angular and axial misalignment
• lightweight aluminum construction aids handling
• electrical insulation for mixed-system setups
