Silvio Fossa S.p.A. is an Italian manufacturer of custom hydraulic and pneumatic cylinders with over 70 years of experience. In-house design starts with the force, stroke, available space and duty cycle of the machine or plant.
Production includes special cylinders for steelmaking, presses, naval and offshore applications, as well as rotary joints and actuators, rolling-mill capsules, accumulators and valves. Product pages explain operation, configurations and applications.
Single acting and plunger cylinders
Powered motion in one direction, with return provided by an external force.
Double acting cylinders
Pressure-powered rod extension and retraction.
Telescopic cylinders
Nested stages for an extended stroke within a compact retracted length.
Rotary joints and rotary cylinders
Fluid transfer and cylinder actuation on rotating assemblies.
Rotary actuators
Rack and pinion convert oil pressure into torque.
HAGC & AWC
Hydraulic capsules for thickness and width control in rolling mills.
Machining
Machining of mechanical components to customer drawings.
