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?

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: 8 Pcs x Motor Rigid Coupling + 1 Pcs x Hex Head Spanner + 32 Pcs x Black Screws,32 Pcs x Silver Screws

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.
