4 Roller Hydro Mechanical
4 Roller Hydro Mechanical
The 4 Roller Hydro Mechanical Series is designed for the highest levels of precision, productivity, and ease of use. With double pre-pinch capability, CNC control options, and a pyramid-type 4-roll layout, this machine ensures consistent performance across a wide range of materials and shapes — from conical to cylindrical and even multi-radius forms. Whether you need batch production or custom forming, this heavy-duty rolling system is built to deliver.
Why Choose 4 Roller Hydro Mechanical
4-Roll Pyramid Design with Double Pre-Pinch
Minimizes flat ends and reduces the need for re-rolling, enhancing output and surface finish.
Top Roll Fixed, Bottom & Side Rolls Move
Bottom roll moves vertically; side rolls tilt hydraulically — allowing advanced shape control.
Built-In Cone Bending
Integrated cone-forming attachment for efficient conical rolling, reducing setup time.
Alloy Steel Rolls
Precision-ground and heat-treated rolls built for strength and long-term durability.
Planetary Gearbox Drive
Power is transferred efficiently to the top roll for smooth, torque-heavy operation.
Hydraulic System at Lower Pressure
Results in smooth motion, energy savings, and less heat — especially effective with thinner sheets.
