Morgan Rushworth DPBH-4 Hydraulic 4 Roll Plate Bending Rolls
The Morgan Rushworth DPBH-4 hydraulic bending rolls are available with roll diameters ranging from 280mm up to the large 680mm machines. The 4 roll design is extremely powerful, with 3 of the rolls hydraulically driven and the fourth lower roll hydraulically adjusted up and down to pinch the material into position. The feature greatly assists the operator, especially during multiple radius bending as the work piece is always held. All models have hydraulic drop end and are supplied with DRO to all three adjusting rolls to indicate roll position.

Frequently Asked Questions
What is the Morgan Rushworth DPBH-4 range designed for?
The Morgan Rushworth DPBH-4 Hydraulic Four-Roll Plate Bending Rolls range is intended for heavy industrial plate rolling. Selmach can review your material, component dimensions and expected throughput to confirm whether it is suitable.
What bending capacity and working length are available?
The Selmach product listing describes published roll diameters from 280 mm to 680 mm; rolling capacity varies by model. Capacity is not a single universal thickness rating: it changes with the exact model, material yield strength, bending length and required finished diameter. Check the model specification before ordering.
Can this machine pre-bend the ends of a sheet?
The range uses four-roll geometry with hydraulic drop end. Pre-bending performance depends on the chosen model and material; provide a drawing if minimising the straight section at the sheet ends is important.
How is the machine operated and adjusted?
The published configuration includes three hydraulically driven rolls and hydraulic pinch adjustment. Confirm the exact controls and any optional adjustments on the quotation, especially if repeat settings are required.
Can it roll stainless steel or aluminium?
Suitability depends on the material grade, yield strength, thickness and required diameter. Published capacities are generally based on specified reference material strengths, so Selmach should check your application before you assume the same thickness rating for stainless steel or aluminium.
What is the minimum diameter the machine can roll?
Minimum achievable diameter depends on roll geometry, material properties, thickness and the model selected. Share the desired inside or outside diameter and material details with Selmach for confirmation; a maximum thickness rating alone does not establish the minimum rolling diameter.
Who is this model best suited to?
This range is particularly relevant to heavy plate fabrication and large-radius work. Selmach can compare it with other manual, powered or hydraulic bending rolls where production volume, pre-bending or component handling may justify a different configuration.
Are servicing and maintenance plans available?
Selmach can discuss preventative maintenance and service-plan options for this machine. The scope, eligibility, visits and response arrangements depend on the machine and the plan quoted; ask Selmach to confirm what is available for your installation.
