3 ROLL DOUBLE PINCH PLATE ROLLS

BETA 3 (16 models ) All Hydraulic Super Heavy Duty Rated at 50,000 psi/ 350 N/mm² material Yield Strength 14 to 61mm / 0.551" to 2.677" thickness 2100 to 4100mm / 82" to 161" width Solenoid valve controls

The Beta 3 is designed to roll steel above 25mm / 1.000" thick with yield strength of 350N/mm² / 50,000 psi to 1.4 the top roll diameter of the machine. COMAL believes that to assure positive results of the function and durability of the roll when it is purchased with the intention of rolling such thick materials day in and day out, meaning 16+ hours shifts, the slide and block system is the answer. COMAL accepts the fact that an orbital path system for the bending rolls' movement with linkage style mechanisms may be used (as in our Kappa design). The fact remains that line contact bearings are inferior, for wear and load carrying capacity, when compared with that of large surface area contact bearings.
Comal is also ready to provide our customers with a choice. If you request, we will offer you a Kappa 3 with the orbital motion system having the same capacities of the Beta 3 machines, at the lower price.
Cone bending on these machines will require you to reduce the machine capacity by 25% on thickness and length. For more information concerning cone bending contact our sales engineers.

4 ROLL DOUBLE PINCH PLATE ROLLS

With brute power and built to last!
The Beta 4 is designed to roll steel above 25mm / 1.000" thick with yield strength of 350N/mm² / 50,000 psi to 1.4 the top roll diameter of the machine.
COMAL believes that to assure positive results of the function and durability of the roll when it is purchased with the intention of rolling such thick materials day in and day out, meaning 16+ hours shifts, the slide and block system is the answer.

The fact remains that line contact bearings are inferior, for wear and load carrying capacity, when compared with that of large surface area contact bearings.

Comal is also ready to provide our customers with a choice.
If you request, we will offer you a Kappa 4 with the orbital motion system having the same capacities of the Beta 4 machines listed below, at the lower price.
Also presented are the capacities at 36,000 psi/ 250N/mm² for comparison with other suppliers' machines, which may be rated at this yield strength and 3 to 5 times the top roll diameter!

Cone bending on these machines will require you to reduce the machine capacity by 25% on thickness and length.
