Kande D32L40 Aluminum Flexible Shaft Coupling 8–16mm 3D Printer

Kande Aluminum Alloy Flexible Shaft Coupling D32L40

Upgrade your 3D printer or DIY CNC build with the Kande Bearings D32L40 Elastic Winding Shaft Coupling. Precision-machined from high-grade aluminum alloy, this flexible coupling delivers smooth, accurate torque transmission between motor shafts and encoders — keeping your prints precise and your machine running at peak performance.

Designed for maximum versatility, the D32L40 accommodates bore sizes from 8mm to 16mm (8, 10, 11, 12, 13, 14, 15, and 16mm), making it compatible with a wide range of stepper motors, servo motors, and encoders. The clamping top-screw design ensures a rock-solid, slip-free grip on your shafts, while the elastic winding construction absorbs minor misalignments and vibrations for smoother operation.

Frequently Asked Questions

Q: What bore sizes does the Kande D32L40 flexible shaft coupling support?

A: The D32L40 aluminum alloy coupling supports bore sizes of 8mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, and 16mm, providing broad compatibility with most standard stepper motors, servo motors, and encoder shafts used in 3D printers and CNC machines.

Q: What is the outer diameter and length of the D32L40 coupling?

A: The "D32L40" model designation directly refers to the dimensions — 32mm outer diameter and 40mm total length. This standard sizing makes it a reliable drop-in replacement or upgrade for most compatible setups.

Q: Is this coupling suitable for 3D printer stepper motors and rotary encoders?

A: Yes. The Kande D32L40 flexible shaft coupling is specifically designed for 3D printer DIY builds, CNC routers, and encoder-driven systems. Its elastic winding construction absorbs minor shaft misalignments and mechanical vibrations, resulting in smoother, more precise motion for your printer or machine.

Q: How does the clamping top screw work?

A: The clamping top-screw mechanism allows you to securely lock the coupling onto the motor shaft without special tools. Simply insert the shaft into the desired bore, tighten the clamping screw, and the coupling grips the shaft firmly to prevent slipping during operation.
