MECCANIXITY 6mm to 6mm Bore Rigid Coupling 25mm Length 14mm Dia Aluminum Alloy Shaft Coupler Connector for 3D Printers DIY Car Boat Red 12pcs, with 12pcs Coupling,1pcs Wrench,96pcs Screws

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.
Connection Bore Diameter: 5.9mm to 5.9mm; Side Diameter: 3.4mm/0.13-inch; Total Length: 25mm /0.98-inch; Outside Diameter: 14mm/0.55-inch; Through Angle: 180 Degree; Material: Aluminum Alloy; Screw Thread Size: M4; In the package of: 12 Pcs x Motor Rigid Coupling + 1 Pcs x Hex Head Spanner + 48 Pcs x Black Screws,48 Pcs x Silver Screws
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.
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.
The rigid type basically does not allow eccentricity and must be fully adjusted during use. Please allow slight errors due to manual measurement.
