Flexible Coupling 5x5mm Aluminum Shaft Coupler for 3D Printer CNC Stepper Motor

Flexible Coupling 5x5mm Aluminum Shaft Coupler for 3D Printer CNC Stepper Motor

The Flexible Coupling 5x5mm is designed to connect two shafts with 5 mm diameters, ensuring smooth torque transmission and reducing misalignment issues in your machine.

• Flexible coupling 5x5mm is made from high-quality aluminum alloy, this coupling offers excellent strength, durability, and corrosion resistance while keeping the assembly lightweight.
• Flexible coupling 5x5mm spiral-cut flexible design absorbs small misalignments, vibrations, and shocks between the motor and driven shaft, improving overall motion precision. Dual set screws on each side provide a secure grip, preventing slippage during high-speed or high-load operations.
• Whether used in 3D printers, CNC machines, robotics, or automation equipment, the Flexible Coupling 5x5mm helps achieve accurate, smooth, and reliable motion transfer.
• Available in different sizes flexible coupling 5x10mm, flexible coupling 6.35x8mm, flexible coupling 8x10mm, flexible coupling 8x8mm.
