Reinforced Shaftless Helical Screw Assembly

Product Overview

Jiahe Conveying's Reinforced Shaftless Helical Screw Assembly is a heavy-duty bulk material handling solution engineered for extreme operating conditions. This advanced design combines the material flow advantages of shaftless technology with structural reinforcements to handle higher loads, more abrasive materials, and more demanding applications than standard shaftless screws.

Technical Specifications

Engineering Features

1. Advanced Reinforcement System
