Plastic Extruder Gearbox of Zlyj Series

The Plastic Extruder Gearbox of Zlyj Series is a specialized transmission device designed for single-screw extruders. It features high precision and a hardened gear surface, along with thrust capabilities. Manufactured with high-strength alloy steel, the gear undergoes carburizing and quenching processes to achieve high precision (grade 6) and high hardness (HRC54-62). It operates with low noise and has a high bearing capacity for thrust, making it reliable and able to withstand larger axial thrust.

The Zlyj Series gearbox is equipped with forced lubrication and cooling systems, ensuring efficient and long-lasting operation. The gearbox is designed with a six-side processing box and can be installed horizontally or vertically according to customer requirements. With its efficiency, low noise, and durability, the Zlyj Series gearbox is a superior choice for extrusion applications.
