Cylindrical gearboxes with parallel shafts for single screw extruders families RXP 700 EST from the company STM these are high-tech and reliable mechanical transmissions for performing specialized tasks of this type. The model range consisting of three overall dimensions is represented by two- and three-stage versions.
The monolithic body is made of cast iron (for all sizes) and, due to the absence of component parts, has high rigidity as opposed to high loads. The internal structure of the gearbox is designed in such a way as to optimize the circulation of lubricants, reduce noise and ensure the tightness of the structure.
Maximum integration due to the specialized gearbox design makes this series the most advantageous offer for equipping extrusion drives, both in price and in practice.
Ruler RXP /EST It covers screw diameters of extruders from 30 mm to 220 mm, as well as over up to 300 mm on request.
