HrR-4 Series

Rectilinear Type Hydraulic Four Rolls

HRR-4 Series 4 Roll Bending Machine

Our HRR-4 series 4 rolls plate roll bending machines are designed for bending medium and thick plates in minutes. Side rolls positioned on both sides of the upper and lower roller and moves on linear line and able to bend very end of plate edge. All rollers are mounted with double row roller bearings. In this way, the generated torque allows the bending process to be performed in fewer steps without any loss. Thanks to the fully symmetrical upper roller bearing system, no diameter difference occurs during bending and is completed in a much shorter time.
