ION Flap Wheels

ION Flap Wheels are designed for intakes and conveyance that need reliable performance when interacting with irregular or variable gamepieces. Similar to compliant wheels, they provide a flexible interface, but their flap-based design introduces intentional slip between the wheel and the gamepiece. This helps smooth out transitions, reduce jams, and improve handling consistency across a wide range of shapes and materials. Each wheel is built from a durable polypropylene core with flexible TPR flaps that can be trimmed to width using the printed cut marks, allowing teams to tailor the wheel to their specific mechanism or gamepiece requirements.

The product family includes 4 inch 2 Flap wheels with a 1/2 inch Hex Bore and 6 inch 6 Flap wheels featuring a MAXSpline bore for higher load applications. The larger 6 inch option provides increased contact area and six independent flaps for more aggressive engagement, while all versions are offered in multiple durometers to fine-tune compliance. Together, these options give teams a customizable, drop-in solution for a wide range of intake designs.
