8mm to 8mm Bore Rigid Coupling Set Screw L22XD14 Stainless Steel,Shaft Coupler Connector for 3D Printers, Motor Accessories,2pcs

8mm to 8mm Bore Rigid Shaft Coupler - Stainless Steel, 2-Pack, 22mm x 14mm, M4 Screws, For 3D Printers and CNCs
✔️ 8mm-8mm rigid shaft coupler, 22mm long, 14mm OD, stainless, M4 screws

These rigid shaft couplers securely connect 8mm to 8mm shafts, ideal for blowers, 3D printers, DIY robots, CNC machines, and stepper motor assemblies. They lock bearings and sprockets tightly on the shaft with a top-tight two-screw clamp, delivering high torque transfer with low inertia and precise responsiveness. The package includes 2 couplers and 8 M4 screws for quick setup. Note: 1-3 mm tolerance due to manual measurement. Through angle is 90 degrees, and the design minimizes rotation gaps for a reliable, maintenance-free connection.
