With the VBH Series we exceed your expectations.
How we exceed your expectations? It’s simple: The all-new VBH Series was created from the belief that every feature, every innovation, must be focused on helping you grow your bottom line. This led our engineers to design the next generation of plate rolls, concentrating on four key areas of machine performance:
STRENGTH: Linear sliding guides and multiple bearings rolls support system.
POWER: High torque reduction unit for reduced number of rolling passes.
PRECISION: Digital control of the rolls parallelism with proportional valves.
CONTROLS: Infinitely variable rolls adjustment speeds, Infinitely variable central lower roll pinching pressure, shell calibration working modes, extended i-diagnostic system... are only some of the features that you can control directly from the operator mobile panel, just moving a finger.

ALG System Antifriction Linear Guides
The linear guides design is the only system that can grant the necessary machine stiffness and the perfect geometry for all kind of bending operations.
The linear design allows a compact geometry of the machine ("minimum centerline distance between the two side rolls" impossible to obtain with the swinging design) that it is essential for the bending precision and accuracy.
The linear design allows to work in the best and ideal geometrical conditions when rolling high yield strength materials, reducing the shell spring back reopening effect and also allows to obtain much smaller bending diameters when compared with the swinging design.
No friction - less than swing design
Direct loads to the plate
Less vertical power on top roll
Lower bending diameter
Built for heavy works
HMB System Heavy Multiple Bearings
Each bending roll is supported by 4 heavy-duty self-aligning spherical roller bearings (double raw type).
Each bearing is oversized in order to withstand the whole bending load.
Thanks to the HMB exclusive design, with four oversized bearings fitted into a swiveling housing, the roll can freely deflects along it’s full width during the rolling process.
This guarantees an optimal distribution of the load on the supports even during the cone rolling process and increase the machine reliability and life.
Moreover, the multi bearing system with swiveling housings design greatly reduces the maintenance and the need for lubrication (permanent lubrication).
The powerful and reliable choice
Full frame extended design
The most heavily sized frame you can find in the market.
Unlikely slim frames covered with thin thickness plates that you can find on all machines in the market our frame design looks definitively oversized.
The exclusive full frame design withstands all bending forces and guarantees stiffness and performances through the years.
This unique machine frames, with extended design for added rigidity and strength, are welded fabrication.
After welding all frames are stress relieved and then machined on cnc milling machines.
Friction free - Maintenance free
AST System Anti-friction sliding technology
Each Rolls supports with machined anti-friction material in sliding area.
This system drastically reduce the maintenance and the sliding friction is lower than in a planetary machine.
More power - More torque
HTT System High transmitted torque
The rolls driving is realized by independent hydraulic motors via planetary gear transmission directly coupled to each driven roll.
The independent rolls hydraulic drive assures and automatic speed compensation between the top and lower rolls and an optimal distribution of the torque on each roll during the working phase.
The HTT system allow the best plate feeding and the highest driving torque of any competitive machine.
A winning combination for those looking for performance of the highest level.
