Hot Days, Cold Nights, and Cracked Wheels: Protecting Casters in Thermally Volatile Environments
Facilities that move between heated interiors and uncontrolled outdoor or cold-storage environments subject their casters to stresses that standard specifications were never designed to handle. Thermal cycling degrades wheel materials at the molecular level, accelerating cracking, deformation, and bearing failure in ways that are easy to misdiagnose. This guide examines the mechanisms behind temperature-driven wear and provides material-level guidance for selecting casters that perform reliably
