Higher precision. Longer lifetime. Zero assembly mismatch

Overview of Screw Shafts

The shaft forms the robust mechanical backbone of the screw assembly. Its primary function is to transmit high torque from the drive system to the entire screw profile while withstanding significant torsional and axial loads. Featuring a standardized spline or keyway designs, it enables the secure mounting and precise axial positioning of all screw and kneading elements. With exceptional tensile and torsional strength, the shaft guarantees reliable power transmission and maintains the structural integrity of the screw configuration, even under the most demanding operating conditions.

Strengths of Screw Shafts

Our screw shafts are engineered to form the robust, reliable foundation of any twin-screw extruder screw configuration. Built for performance and longevity, they offer:

• Versatile Spline Profiles

  Precision-machined in multiple forms—including single key, rectangular, hexagonal, and involute—to ensure perfect torque transmission and secure element mounting.

• Broad Size & Capacity Range

  Covering diameters from 10mm to 200mm and custom lengths up to 12 meters, supporting configurations from lab-scale to large industrial twin-screw extruders.

• Superior Strength & Material Selection

  Manufactured from a range of high-grade materials to meet demanding torque requirements, reliably serving applications from Grade 5 up to Grade 18.

• Advanced Cold Forming Technology

  Utilizing globally leading cold forming processes for spline formation, enhancing material strength, improving fatigue resistance,and ensuring exceptional dimensional accuracy.
