5mm to 5mm Bore Rigid Coupling Aluminum Alloy Shaft Coupler Connector for 3D Printers DIY Car Boat Red 12pcs

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. Are there any advantages of the product? Made of high-strength aluminum alloy 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 rotation gap and the elastic effect can compensate for the symmetrical angle 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.
