Bare Cast Rubber Extrusion Gear Reducer

The Bare Cast Rubber Extrusion Gear Reducer is a robust power transmission unit engineered for continuous heavy-duty operation in rubber extrusion lines.   Its housing is constructed from high-grade ductile iron with a thickened, ribbed structure, which provides exceptional rigidity and vibration damping, ensuring stable performance even under the extreme load conditions common in rubber processing.   The internal gears are precision-machined from alloy steel and undergo a carburizing and quenching process, resulting in a hardened tooth surface with a hardness rating of HRC 58-62, which delivers exceptional wear resistance and extends the service life of the reducer.     A key feature of this reducer is its bare cast construction, which eliminates the need for paint coatings, making it ideal for high-temperature environments where coatings may degrade.   The hollow output bore provides a secure, backlash-free connection to the extrusion screw, improving torque transmission efficien…
