ProStar™ Double Pinch Ring Roller - PRSRH150

Create Repeatable Bends and Complex Parts with No Wasted Straight Material

Praxair’s ProStar™ high-capacity tube roller bends round tube, pipe, sections, bar and angle iron and handle structural projects, shipyard building and playgrounds with ease.

Programmable stops for each shaft help you take on production runs with confidence. Double-pinch design prevents wasted straight material at the ends of parts — a common problem associated with some roll benders. Employing three inverter-driven rolls and a direct-drive transmission, the PRSRH150 is well-suited for your high-production projects.

3 Driven Rolls, 220 V, 3-Phase Power
