For use in temperatures below 5°C (40°F) and above 30°C (85°F), the performance of the castor can be impaired, particulary the load capacity, as stated, can be affected when used in temperatures below or above these stated limits. Special components must be specified. Castors are made of component parts. The manufacturer is only liable for the original components incorporated in the assembled castor. When selecting a castor, it is necessary to take into consideration the technical details in the published charts for a castor.
