High Torque Gearbox For PET Extruder Machine
ZT-N Twin Screw Extruder Gearbox Introduction
The ZT25N gearbox is specially engineered for co-rotating twin screw extruders, offering a compact design with high torque output to meet the demanding needs of compounding and extrusion applications. It features hardened and precision-ground gears made from 20CrNi2MoA alloy steel, ensuring excellent wear resistance and long service life under heavy-duty operation. The housing is built from high-strength ductile iron, providing both stability and vibration reduction. Designed with forced lubrication and efficient cooling options, this gearbox delivers consistent performance in high-load and continuous processing environments. Compatible with most standard twin screw setups, the ZT25N is an ideal choice for small-to-medium extruder lines.
----Double drive design enables the B axis to be driven by two gears without increasing the tooth width.
----Optimal structure and complex assembly lead to the cost rise.
----All bearings are sourced from global recognized brands,so output torque is more stable.
---Streamlined design,the end of gearbox cover can be opened,easy to install and replace.
