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. Made of high-strength aluminium alloy with integrated structure, maintenance-free, oil-resistant and corrosion-resistant. Rigid coupling, high torque with stiffness, low inertia and excellent sensitivity Aluminum Alloy Shaft Coupler Uxcell 1/4 Inch To 1/4 Inch Bore 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. 3D Printer Coupler Uxcell 5mm To 8mm Bore Rigid Coupling Set Screw L25XD20 25mm Length Set Screw Coupling Widely used in blowers,3D printer,DIY robots,CNC machine,stepper motors,etc.
