Where is a thrust bearing typically installed on a screw conveyor?

A thrust bearing is crucial in a screw conveyor as it is designed to absorb thrust loads, which are axial forces directed along the shaft. Typically, the most logical placement for a thrust bearing in a screw conveyor is at the tension end. This is because the tension end experiences significant axial forces due to the tension in the conveyor's screw section, especially when the screw is loaded with material.

By installing the thrust bearing at the tension end, it effectively manages these axial loads and prevents excessive wear and tear on the bearing and other components of the conveyor. This placement also assists in maintaining the alignment of the screw shaft, contributing to the overall efficiency and longevity of the system.

In contrast, placing a thrust bearing at the drive end, middle, or discharge end would not efficiently address the operational demands placed on the conveyor, leading to potential performance issues and increased risk of failure.
