Why Choose This Eccentric Crank Wheel?
The eccentric (off-center) design converts rotational motion into linear or oscillating movement — a fundamental mechanism used in engines, robots, and model machines. The aluminum alloy construction keeps weight low while maintaining the rigidity needed for precise, repeatable motion. The included M2 screws mean you're ready to install right out of the box.

Frequently Asked Questions
Q: What is an eccentric crank wheel used for in DIY projects?
A: An eccentric crank wheel converts rotary motion into linear or oscillating movement. It is widely used in DIY robotics, mini mechanical models, small engines, and automated mechanisms where a crank-driven motion is needed.
Q: What screws are included with the aluminum eccentric crank wheel?
A: The set includes 3× M2×8 screws, so you have everything needed to mount and secure the wheel in your project right out of the box.
Q: Is this wheel compatible with a 2mm shaft?
A: Yes. The center bore diameter is 2mm, making it compatible with standard 2mm diameter shafts commonly used in small-scale DIY and robotics builds.
Q: Can I use this crank wheel disc with standard hobby robotics kits?
A: Absolutely. The M2 thread holes and 15mm diameter make this wheel disc an excellent fit for a wide range of hobby robotics kits, mini mechanical assemblies, and maker projects that use M2 hardware.
