4-Roll Heavy-Duty Benders

ProStar PRS4RHD Series Rolls
™

Built for high productivity and ease of SUPREMELY CONSTRUCTED
use, ProStar’s “supreme duty” 4-roll Massive end frame weldments on the
double-pinch plate rolls are solidly 4RHD Series provide superior performance,
constructed to extend machine life and strength and rigidity. Direct linear-guide
minimize maintenance. The PRS4RHD geometry delivers 100% thrust to the rolls,
Series machine uses 75% fewer moving producing a better pre-bend, even to 1.1 ×
parts when compared with swing-arm top roll dia. All 3 and 4 Roll ProStar HD plate
and torsion bar plate roll designs.
rolls are built using an identical advanced
technology platform: digimatic controls, anti-
friction guides, hydrotronic automatic digital
roll balancing, plug and play socket-type
wiring harness, independently-driven rollers
and multiple oscillating, self-aligning tapered
roller bearings.
