The HACO 3 roll double pinch plate bending rolls use planetary guides to keep a bigger surface of the plate under pressure during rolling. By doing this, we are able to roll tighter diameters than our competitors.

This technology makes the HACO 3 roll double pinch plate bending roll one of the best rolls on the market today.

We use electro-welded frames on and 3 powered rolls with hydraulic motors installed directly on them. The 2 bottom rolls have a planetary movement and the rolls parallelism is controlled by massive torsion bars. We use off the shelf parts, worldwide available.

The rolls are made of high quality forged steel, induction tempered and hardened and we polish the rolls after hardening. We also supply special rolls for certain jobs upon request.

We use double spherical roller bearings for the rolls in stead of bushings to eliminate bushing tolerances and friction which results in energy loss.

The bearings are pre-lubricated and protected by a special washer which doesn't need any lubrication for the entire life of the machine

We connect the hydraulic motors together with planetary gear drives directly on the rolls. This has the advantage of a very efficient power transmission from the motors to the rolls without secondary transmissions and clutches.

This system offers the best torque under every work condition.

On the left side you can see the planetary movement of the 2 bottom rolls.

The parallelism of the rolls is controlled by massive torsion bars. We eliminate parallellism problems often found on electro hydraulic and electronic systems. This system also gives you the possibility of tilting the rolls for cone work and return to the initial position in a couple of seconds.
