How is the connection between the shaft and wheel handled?

For medium and heavy-duty pulleys, expansion sleeves are used to connect the shafts and wheels, solving stress concentration issues and eliminating internal welding stress.

What quality control measures are applied to the pulley?

Measures include non-destructive testing of welds, magnetic particle or ultrasonic testing of the wheel hub, and static balance tests to achieve G40 accuracy.
