How is the shaft connected for heavy-duty pulleys?

For medium and heavy-duty pulleys, the shafts and wheels are connected by expansion sleeves to solve stress concentration issues.

What is the static balance accuracy?

All driving and directional pulleys undergo static balance tests to achieve G40 accuracy.
