The eccentric cam (also called the snail cam) works together with the graduated knob: as it rotates, it gradually moves the blade or the support plate, adjusting slice thickness.

How to choose the right part: check the outer diameter, the centre hole diameter and the slicer model — measurements specific to each manufacturer, not standardised across brands.

Variable-pitch conical version: on some models (e.g. Galileo Evo, Leonardo Evo) the cam is conical, with variable pitch along its travel — allowing finer thickness adjustment than a traditional cam.

Compatibility by brand: available for Abo (mod. 220 Mignon, mod. A250F), Arsa, Atoma (mod. Europa), Sirman (mod. Mirra, CE) and for the Leonardo/Galileo/Kelly range.

For the connected graduated knob see Graduated Knob; for other parts go back to Slicer Spare Parts.

Frequently asked questions

How do I measure the eccentric cam I'm replacing?
Measure outer diameter and centre hole diameter with a caliper, and check whether your machine has the traditional or conical variable-pitch version.

Why is the cam conical on some models?
The variable-pitch conical profile allows finer, more progressive thickness adjustment than a constant-pitch cam.
