JE High Load Bearing Series Single Screw Extruder Reducer

JE High Load Bearing Series Single Screw Extruder Reducer

The JE high-load series single-screw extruder reducers are specifically designed for plastic and rubber extrusion. Featuring a modular structure and high-specification thrust bearings, they perfectly handle heavy-duty conditions. Inheriting the essence of the ZLYJ series, they are equipped with high-precision hardened gears, thrust bearing seats, and high-strength alloy steel components to ensure durability and reliability. Complementing the SZ/SZL conical twin-screw reducers, the former increases torque output through the reduction gearbox and transmits it to the distribution box, achieving counter-rotating synchronous drive of the two screws.

Advantages of 

JE High Load Bearing Series Single Screw Extruder Reducer

• The JE High-Load Series single-screw extruder reducers are equipped with oversized thrust bearings and hardened gears, easily withstanding tons of axial loads and ensuring stable and reliable heavy-duty extrusion.

• Using carburized alloy steel, precision-ground gears and imported oil seals, they offer excellent wear resistance and sealing, extending service life by 20-30%, significantly reducing maintenance costs.

• The helical gear design and balanced torque distribution ensure smooth operation and noise levels below 75dB, enhancing production safety and efficiency.

• Optimized gear ratios and low-friction bearings deliver transmission efficiency up to 95%, saving 10-15% energy compared to traditional reducers, accelerating processing speeds and increasing output.

• The modular structure supports customizable output speeds, ratios, and mounting methods, and is compatible with screw diameters from 40 to 530mm, making it suitable for a wide range of extrusion applications.

• Forced lubrication and auxiliary cooling systems prevent overheating, while high-precision bearings provide overload protection, ensuring trouble-free processing of high-temperature, high-viscosity materials.

• The overall high-reliability design reduces unplanned downtime and ensures consistent output quality and continuous production in heavy-duty industries such as plastics manufacturing.

FAQ of JE High Load Bearing Series Single Screw Extruder Reducer

1. What is the JE High Load Bearing Series Single Screw Extruder Reducer?

   The JE series is a high-precision hardened gear reducer with integrated thrust bearings, specifically engineered for single-screw extruders in plastic and rubber processing. It features a compact design with a hollow output shaft for direct screw integration, handling high axial loads from screw recoil while ensuring smooth torque transmission.

2. What are the key technical specifications?

   Gears and shafts are made from high-strength alloy steel (carburized and quenched to HRC 54-62 hardness), with precision grinding to GB10095-88 Grade 6 accuracy. Gear ratios range from 6.3:1 to 20:1, input speeds up to 1500 RPM, and thrust bearings support axial loads up to several tons. Efficiency exceeds 95%, with noise levels below 75 dB.

3. What applications is it suitable for JE High Load Bearing Series Single Screw Extruder Reducer?

   It is ideal for heavy-duty single-screw extrusion in plastics (e.g., pipes, profiles, sheets), rubber compounding, and recycling. Compatible with screw diameters from 30mm to 530mm, it excels in high-pressure, high-viscosity processes like EPS, PE, and PVC extrusion.

4. How should it be installed JE High Load Bearing Series Single Screw Extruder Reducer

   Mount horizontally or vertically using foot or flange options. Align the input shaft with the motor via flexible coupling, ensuring the hollow output shaft connects directly to the screw. Preheat lubrication oil if ambient temperature is below 0°C. Rotation is bidirectional, but some models default to clockwise output—verify during setup.

5. What lubrication and cooling methods are recommended?

   Use medium-pressure gear oil (e.g., N220 or equivalent) for splash lubrication in smaller models; larger units (ZLYJ225+) require forced circulation with an oil pump. Natural cooling suffices for low loads, but auxiliary fans or coolers are essential for high-output operations to prevent overheating. Change oil every 3-6 months based on usage.

6. What is the expected service life and maintenance schedule?

   With proper lubrication and load management, gears and bearings last 10,000-25,000 hours (thrust bearings ~12,000 hours typical). Perform daily visual checks for leaks, monthly oil analysis, and annual gear inspections. Avoid exceeding rated torque to minimize wear
