What Is a Custom Heavy Duty Hydraulic Cylinder?
A heavy duty hydraulic cylinder is a linear actuator designed for extreme operating conditions — massive loads, high pressures, severe shock, and continuous operation in harsh environments. Unlike standard cylinders, heavy duty cylinders feature oversized bores, thicker walls, heavy-duty seals, and reinforced mounting systems.
With a custom heavy duty cylinder, you get a cylinder engineered to your exact specifications — bore sizes up to 30 inches, working pressures up to 10,000 PSI, custom mounting configurations, specialized seal materials, and extreme temperature designs. These cylinders are built to last in the world's most demanding applications — mining, steelmaking, tunnel boring, hydropower, and heavy marine.
