Need production from your ring rolling machine? With its 4-1/2” schedule 40 pipe capacity, the R-H120 is the machine you want. The double pinch design of the R-H120 helps minimize those money wasting pieces of straight that are commonly found at the start and finish of the bend by allowing the operator to pre and post bend the material. The R-H120 is considered a double pinch roll bender since the top roll is fixed and the two bottom rolls are on independent hydraulic cylinders to do the forming.
