Aluminium Alloy Elastic Coupling for 3D Printers:

• Made from high-quality aluminium alloy.
• Ensures a strong and durable connection between stepper motors and lead screws.
• Ideal for precision and stability in 3D printing processes

Specifications:

• Type: Elastic (flexible) shaft coupling
• Material: Constructed from high-strength aluminum alloy, providing a lightweight, durable design with resistance to corrosion.
• Dimensions:
• Bore Diameter:
• Side A: 3 mm
• Side B: 4 mm
• Outer Diameter: 18 mm
• Length: 25 mm
• Elastic Insert: Contains a polyurethane or element, absorbing vibrations, compensating for minor shaft misalignments, and reducing mechanical noise.
• Set Screws: 2 Set screws per bore to ensure secure attachment to the shafts.
• Flexibility: Designed to accommodate angular, axial, and radial misalignments, providing smooth, precise torque transmission.
• Performance:
• Torque Capacity: Typically handles up to 1 Nm of torque.
• Maximum Speed: Capable of handling speeds up to 8,000 RPM.
• Misalignment Compensation:
• Angular: Up to 1
• Radial: Up to 0.2 mm
• Axial: Up to 0.3 mm
• Commonly used in:
• 3D printers (connecting stepper motors to lead screws or threaded rods)
• CNC machines
• Robotic systems
• Small automation devices
• Ideal for applications requiring low backlash, vibration damping, and precise power transfer
