Stepper Motor Flexible Coupling 5mmx8mm

This is 5mm to 8mm Aluminium Flexible Shaft Coupling with outer diameter (OD) of 19mm and Length (L) of 25mm. Widely used in CNC machine to connect stepping motor to encoder, or in servo motor and other gearing machines. It is also widely used in 3D printer :) Example in this video, this type of coupler offers less backlash to the motion (by joshendy):

Absorption of parallel, angular misalignments and shaft end-play by spring action. Widely used in drive systems for encoders, instrumentation, lead screws, small pumps, feed rollers and anywhere a light to medium duty, torsionally flexible coupling is required.

• The structure is simple, easy to install, buffer, damping, convenient to disconnect
• The size is complete and the surface is smooth
• Story reversal characteristics are identical
• The elastic connection, you can absorb vibration, compensate radial, angular and axial misalignment
• Shaft coupler is often used to connect servo motor stepper motor, encoder screw driving machine platform, etc

Specifications:

• Color: Silver
• Type: Flexible Shaft Coupling
• Material: Aluminium Alloy
• Use set screw to fasten coupler to shaft, 2 set screws at each shaft
• Inner Diameter: 5mm x 8mm
• Outside Diameter: 19mm
• Length: 25mm

• 1 x Stepper Motor Flexible Coupling 5mmx8mm
