Unless a component is adequately sealed, chemicals and particulates can get into internal component mechanisms, causing damage, build-up and clogging, creating fertile ground for microbial growth. Deploying inadequately sealed motion control technology in harsh environments will require additional cost of enclosures and maintenance, and potentially more frequent maintenance.
Every component should be sealed, including motor mounts. Wipers, seals and gaskets are integral to success. The wiper brushes contaminants from the extension tube during operation and prevents water intrusion. The seals back up the wipers. Gaskets provide sealing between housings, cover tubes, motors and rear mounting components.
One of the best indicators of a system’s sealing effectiveness is International Protection Marking, or IP Code. Its ingress protection (IP) rating is the global standard for measuring protection from the ingress of solid objects and liquids. The IP rating specifies the degree of environmental protection an enclosure provides against foreign materials that could impact performance.
