These represent our "historic" production.
In fact, our company begins a production precisely with this product. Our series of fixed light alloy pulleys, with diameters of between 40 and 500 mm, and 1 to 5 races, was realized by paying special attention to the materials, the machining and construction geometries, in order to fully satisfy the most varied requirements of use. Moreover, with the same criterion we also produce trapezoidal step pulleys. Our special FIPILL alloy, perfected over the years, used for this pulley series permits hard oxidation treatment which allows hardnesses of between 450 and 700 Vickers to be obtained.
