Comparison of shaft designs for conveyor pulleys and idler ...

The shaft for pulley and the idler must be designed to handle stress and deflection criteria. The deflection criteria are needed to provide ample life for the product carried by the shaft, not necessarily the shaft itself. This is and will remain the case unless one uses a connection system that will align itself dynamically to the shaft. References
