In summary, the hub dust seal is a small but essential component of your machinery that plays a big role in protecting the bearings and ensuring optimal performance. By keeping these seals in good condition and replacing them when necessary, you can prolong the life of your equipment and avoid costly downtime. So don't overlook the importance of these tiny seals – they may be small, but they are mighty in their ability to keep your machinery running smoothly.

Types of Seals

Because of their aerodynamic design, some modern racing cars create enough vacuum to lift a manhole cover off its recess. During races on city streets, manhole covers must therefore be welded or locked down to prevent injury. In 1990, during the Group C World Sportscar Championship race at Circuit Gilles Villeneuve (located in a public park in Montreal, Quebec), a Brun Motorsport Porsche 962 struck a manhole cover that was lifted by the ground effect of the car he was following, a Courage C24 Porsche. This caused the trailing Porsche to catch fire, and safety issues ended the race shortly afterwards.^{[citation needed]}

Despite their weight and cumbersome nature, manhole covers are sometimes stolen, usually for resale as scrap, particularly when metal prices rise.^[3][4][5][6]

- Accessibility and Maintenance Drainage systems should be accessible for maintenance purposes. Covers that are easy to remove and replace will ensure that any necessary upkeep can be carried out efficiently.
