IMPROVE LIP SEAL PERFORMANCE AND INCREASE SAND RESISTANCE WITH A LOW-COST GRAPHITE SHAFT COATING

Lip seals are vital components that serve two primary purposes – keep liquids/lubricants in and keep sand/contaminants out. An additional task is to confine pressure. Test study results indicate that self-polishing Additive Abradable Graphite Coatings (AAGC’s) will protect sealed rotating components from sand, and extend lubricant maintenance interval on gearboxes, PTO’s, and the like.
