What is the rotational fatigue strength guarantee?

The pulley, including the welding part, is guaranteed to have a rotational fatigue strength of over 10^8 cycles.

How are the shaft and wheel connected in heavy-duty pulleys?

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