D35L50 Flexible Jaw Shaft Coupler CNC Plum Coupling 8–22mm

D35L50 Flexible Jaw Shaft Coupling – CNC-Ready Plum Coupler

Upgrade your CNC machine, stepper motor, or servo drive with the CF-03/BW Series D35L50 Flexible Jaw Shaft Coupling. Engineered from high-grade aluminium, this spider/jaw-style coupler delivers smooth, reliable torque transmission while absorbing minor misalignments between shafts. The flexible polyurethane spider insert reduces vibration and protects connected components from shock loads — making it an essential component for precise motion control systems.

Made in Mainland China.

Why Choose a Jaw/Spider Coupler?

The jaw (plum) coupler design splits into two aluminium hubs and a centre spider insert. This three-piece construction allows for easy installation without moving connected components, and the flexible spider absorbs vibration and compensates for small shaft misalignments — protecting your motors, encoders, and lead screws from unnecessary wear.

Ideal Applications

• CNC routers, milling machines, and laser cutters
• 3D printer lead screw connections
• Stepper and servo motor shaft connections
• Robotics and automation equipment
• General power transmission assemblies

Frequently Asked Questions

Q: What bore sizes are available for the D35L50 flexible jaw shaft coupler?

A: The D35L50 coupler is available in the following bore sizes: 6, 8, 10, 12, 12.7, 14, 15, 16, 18, 19, 20, and 22 mm. You can mix and match bore sizes on each hub to accommodate mismatched shaft diameters.

Q: Is this coupler suitable for CNC machines and 3D printers?

A: Yes. The CF-03/BW series D35L50 jaw coupler is widely used in CNC routers, 3D printers, laser cutters, and any application requiring reliable torque transmission between a motor shaft and a lead screw or ballscrew. Its flexible spider insert helps dampen vibration for smoother operation.

Q: What material is the D35L50 jaw coupler made from?

A: The hubs are machined from aluminium alloy for a lightweight yet strong construction. The spider (plum) insert is made from polyurethane, which provides flexibility, vibration dampening, and misalignment compensation.

Q: How do I install the flexible jaw shaft coupler?

A: Slide each aluminium hub onto its respective shaft and secure with the set screws. Place the polyurethane spider insert between the two hubs so the jaws interlock. No special tools are required — the three-piece design allows installation without disassembling your machine's drive system.
