Feature

●Connection hole diameter: 3.17mm to 6mm; Total length: 25mm/0.98", Outer diameter: 14mm/0.55", with M4 screws
●Widely used in blowers, 3D printers, DIY robots, CNC machines, stepper motors, etc. Similar to rigid clamp couplings, shaft couplings are used to hold bearings and sprockets firmly on the shaft, and are used in engine and transmission assemblies.
●Rigid Top Fixed coupling with 2/4 screws to hold the shaft in place, high torque with rigidity, low inertia and excellent sensitivity.
●Note: The rigid type generally does not allow eccentricity and it must be fully adjusted during use.
●The one-piece design of the set screw clamp makes it easy to place the parts on the shaft and control the holding capacity of the coupling.


Description
