About this item

• •What is this?
• •Couplings are widely used in blowers, 3D printers, DIY robots, CNC machine tools, stepper motors, etc. Similar to rigid clamp couplings, shaft couplings are used to secure bearings and sprockets tightly to shafts and are used in motor and transmission components. Suitable for model cars, model ships, hardware, mechanical drive occasions, etc.
• •What will I get?
• •Connection Bore Diameter: 4mm to 5mm
• •Screw Thread Size: M3*0.5
• •Total Length: 20mm /0.79-inch
• •Outside Diameter: 9mm/0.35-inch
• •Material: Brass
• •In the package of: 1 Set x Rigid Coupling (Include 4pcs Coupling + 16pcs Screws + 2pcs Wrench)
• •Are there any advantages of the product?
• •Made of brass, it has good electrical conductivity, high strength, high hardness, integrated structure, maintenance-free, oil-proof and corrosion-resistant. Top-tight rigid coupling, high torque, high rigidity, low inertia and excellent sensitivity. There is no rotational play and the elastic effect compensate for symmetrical angular misalignment.
• •How to use it?
• •Single piece set screw clamp design makes it easy to set up the items on the shaft and control the holding capacity of the coupling.
• •What should I notice?
• •The rigid type basically does not allow eccentricity and must be fully adjusted during use. Please allow slight errors due to manual measurement.
