The industry of steel, of aluminum and of the other metals is one of the main branches of our activity, representing a vast share of our turnover. During our more than sixty years of business life, we have supplied, and are still supplying,  most of Italian, European and worldwide plant manufacturers and end-users in this field, with gearboxes of all dimensions and sizes, ending with our latest behemoth: a 135.000 kg gearbox for a hot rolling mill for aluminum.

Gabbia

(Gearbox for rolling mill stand drive with double-helical pinion stand and speed gear shift – weight 35.000 kg)

Our technical and manufacturing expertise can address almost any need in this field having successfully built gearboxes for the most demanding applications, such as:

  • gearboxes for rolling mill stands, with the following characteristics:
    • helical gears in case hardened and tempered steel, ground on the teeth profile, or in through hardened steel, also with double-helical gears
    • suitable to withstand high peripheral speeds, allowing the transmission of high torques and at the same time to achieve high rotation speeds
    • availability of solutions with gear shifts actuated manually or by means of hydraulic cylinders
    • shafts equipped with roller bearings (spherical rollers, cylindrical rollers or tapered rollers), with all the provisions required by the rotation speed and by the positions of the shafts, only purchased from primary manufacturers
    • suitable for horizontal, vertical and even for convertible stands
    • robust welded steel casings, subjected to stress relieving heat treatment before machining
    • forced feed lubrication of gears and bearings by means of a centralized supply system or by means of an on-board circuit

aspo

(Gearbox for coiler, complete with motor, disc brake and on-board lubrication system)

  • Gearboxes for coilers (and uncoilers) with the following characteristics:
    • helical gears in case hardened and tempered steel, ground on the teeth profile, or in through hardened steel
    • spindle shaft integrated in the gearbox, with its dedicated bearing system suitable to withstand the external loads during operation
    • available also with gear shift
    • possibility of supporting the motor on-board the gearbox
    • available with sliding baseplate, moved by hydraulic cylinders
    • possible integration of various subsystems, such as pressure rolls or stripping plates of our design and manufacture
    • supply of the on-board high pressure hydraulic piping
    • on-board lubrication system
  • all the other gearboxes which find their application in the metal industry, such as gearboxes for shears, tilting converters, flatteners, tube straighteners, twin drives, edgers… 
  • gears and pinions supplied as spare parts or of new design, in case hardened and tempered steel, ground on the teeth profile, or in through hardened steel, also double-helical.

All our gearboxes can be prepared for the installation of an array of sensors, in order to monitor their vibration level, their temperature and all their operating conditions

We can also supply complete gearboxes interchangeable to existing ones, even if not of our original supply, and we can perform complete mechanical overhauling of all types of gearboxes.
