Four-Way Shuttle Wheel Units: Why Integrated Wheelsets Outlast Multi-Part Assemblies
Four-way shuttles put wheel units through one of the harshest duty cycles in intralogistics: combined loads, continuous operation and rapid start-stop motion at high acceleration. This article explains why conventional multi-part wheel units fail first — and how the THB WSD/WSN integrated wheelset answers with a deliberate sequence of design choices: the right structure first, the right material last.
