Custom-Engineered Gearbox for Extruder | ZHITIAN’s Full Series for Twin Screw Extruders
ZHITIAN specializes in the design and manufacturing of gearboxes for twin screw extruders, offering five distinct series tailored to meet the needs of various industries, output capacities, and processing conditions. With over a decade of engineering experience, ZHITIAN delivers high-performance gearbox solutions that ensure smooth power transmission, durability, and energy efficiency.
Five Gearbox Series for Twin Screw Extruders
- ZT-N Series – Radial Torque Split Design (≤13 Nm/cm³)
Covering extruder models from 20 to 177, the ZT-N series features a radial torque distribution structure. Torque is equally split into intermediate shafts C/D and then transmitted to the output shaft B via symmetrical gear engagement. This design ensures stable power output, enhanced load capacity, and long service life. Multiple gear ratio options available. - ZT-Z Series – Optimized Radial Torque Split (15 Nm/cm³)
Based on the ZT-N structure, the ZT-Z series improves torque performance up to 15 Nm/cm³. It's an ideal upgrade for manufacturers seeking enhanced output and durability without changing installation dimensions. - ZT-E Series – High Torque Hybrid Power Split (16–18 Nm/cm³)
Engineered for ultra-high torque applications, ZT-E combines radial and axial torque splitting to maximize transmission efficiency and power capacity. Particularly suitable for industries where energy-saving, reduced equipment count, and lower operating costs are critical. - TDSN Series – Economic Gearbox (≤7 Nm/cm³)
A cost-effective choice for general-purpose extrusion lines, balancing performance and affordability. - STD Series – Mid-Level Economic Gearbox (≤9 Nm/cm³)
Designed for moderate capacity applications with stable performance and lower cost, ideal for small to medium-sized production lines.
Customized Gearbox Solutions for Specialized Industries
In addition to the standard series, ZHITIAN also develops custom gearboxes for specific sectors:
- TDF Series – for food and feed extrusion
- ZTA Series – for lithium battery materials
- SANB Series – for triple-screw extruders
