Core offering

SIAP manufactures precision gears and high-complexity gear components including cut steel gears (cylindrical helical and spur), ring gears (epicycloidal), bevel gears (straight and spiral), and toothed shafts, supplying them to major OEMs in automotive, truck, agricultural, construction, rail, industrial, and material handling sectors. The company operates a vertically integrated production facility in Maniago, Italy, with in-house heat treatment, gear cutting (Gleason and Oerlikon systems), finishing (lapping, grinding, shaving, press hardening), and metallurgical laboratory inspection, and has expanded into high-volume truck gear production and automotive axle assembly operations.

Product overview

SIAP is the Carraro Group's center of excellence for quality components and high-complexity precision gears. The company operates a highly verticalized production facility in Maniago, Italy, producing four main product families: Cut Steel Gears (cylindrical helical and spur gears), Ring Gears (epicycloidal ring gears for planetary drives), Bevel Gears (straight and spiral bevel gears for differentials and drivelines), and Toothed Shafts (drive shafts and output pinions). In recent years, SIAP has expanded into high-volume gear production for the truck sector at its Montereale Valcellina plant and assembly operations, including producing axles for the INEOS Grenadier off-road vehicle at its new Automotive plant in Maniago. The product portfolio serves diverse application areas including automotive, trucks, agricultural equipment, construction equipment, rail, industrial, and material handling sectors.
