Description
CNC Jaw Coupling D20L25 – Aluminum Flexible Spider Coupler for Stepper Motor & Lead Screw
Connect your motor to a lead screw with this CNC Jaw Coupling D20L25. Made from high-quality aluminum with a polyurethane sleeve, this flexible jaw coupling corrects misalignment and handles higher torque than standard flexible couplings.
The CNC Jaw Coupling D20L25 is perfect for connecting stepper motors to lead screws on CNC machines, 3D printers, and automation builds. The jaw design allows for higher torque transfer while the flexible spider absorbs vibration and compensates for misalignment.
With a 25mm length and 20mm outer diameter, this CNC Jaw Coupling D20L25 is available in a wide range of shaft combinations from 5x8mm to 10x10mm. Whether you’re building a new machine or replacing a worn coupling, this part delivers reliable motion transfer.
