sourcing map 8mm to 12mm Bore Rigid Coupling Set Screw L25XD20 Aluminum Alloy,Shaft Coupler Connector for 3D Printers, Motor Accessories,2pcs

• Connection Bore Diameter: 8mm to 12mm; Total Length: 25mm /0.98 inch, Outside Diameter : 20mm/ 0.79 inch; with M4 Screws
• Widely used in blowers,3D printer,DIY robots,CNC machine,stepper motors,etc. Similar to rigid clamp couplings, shaft couplers are used to hold bearings and sprockets tightly on the shaft, and are used in motor and gearbox assemblies.
• Top tight type rigid coupling with 2/4 screws to hold the shaft tightly; high torque with rigidity, low inertia and excellent sensitivity.
• NOTE: The rigid type basically does not allow eccentricity, and it must be fully adjusted during use.
• 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.
