ReviewsFlexible Shaft Couplings

Aopin Flexible Beam Couplings 6mm to 6mm Flexible Coupler Shaft for 3D Printer, Length 25mm / 1\ Motor Coupler Connector, Great Apply for Model Shaft, CNC Machine, Motor Guide, DIY Encoder 2 Pcs

Size：Diameter 25mm Length 30mm/Diameter 1inch Length 1.2inch. Bore 8-8mm/0.3-0.3inch. Type: Plum shaped.
Material: Using Aviation Aluminum with corrosion resistance High Hardness, High Precision, Anodized Surface Treatment, Strong and Durable. Spider Material (Elastomer) Uses T-PUR, Longer Service Life.
Super Torque: Can Absorb Vibration, Appropriate a Large Torque Transmission.High Hardness,Durable,and Excellent Response,Not Easy to Loosen.
Vibration-damping: Flexible Spider Couplings Offset Angular, Radial and Axial Shaft Displacement Within Defined Ranges. The Elastomer Dampens Shock and Torsional Vibrations in The Drive Train.
Wide Range of Usage: Flexible Couplings is Suitable to Offset Axial, Radial and Angular Displacements and Dampen Vibrations and Torque Shocks for 3D Printer DIY Encoder CNC Router Machine Servo Stepped Motor and Engraving Drilling Milling Machine.

For use with Martin Quadra-Flex series flexible couplings (sold separately).
Cast iron for non-corrosive applications where strength and heat dissipation are factors and weight is not.
Transfers shock and misalignment to the center element of the coupling assembly for reduced wear on the shaft assembly.
Teeth help to distribute torsional load across the flange and sleeve, reducing wear and extending service life.

Connection Diameter: 10mm to 10mm, Total Length: 22mm /0.87 inch, Outside Diameter : 16mm/ 0.63 inch.
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..
