Cylindrical cams are robust and precise solutions at the heart of many systems for converting constant rotary motion into intermittent or oscillating movements. They can be manufactured with a groove or ridge profile, with the ridge variant ensuring a play-free roller cam engagement, guaranteeing preloaded stops and maximum dynamic stability. The study of the geometric configuration, laws of motion, tolerances, materials and heat treatments allow us to design and manufacture the ideal cam for each specific application.
