Often unusual operating conditions require selection of casters and wheels with special features. Listed below are several guidelines for selecting casters for special conditions:
• The presence of acids, oils or corrosive chemicals require wheels made of polyurethane, phenolic, polyolefin or steel.
• Extreme temperatures require special bearing lubricants or plain bore bearings.
• Never use rubber tread wheels in corrosive environments.
• In hospitals, bakeries and food processing plants where cart washings are required, select nickel-plated casters with raceway grease seals and zerk grease fittings.
• For very frequent wash down applications or wet environments, specify stainless steel casters.
• In textile plants and laundries, specify casters with thread guards to reduce the collection of thread, string and general floor debris.
• For office machines such as copiers which require a low load height, choose Flywheel business machine casters and low profile casters.
