Pin Dust Seals VAW ,VAY

The VAW series by South Korean manufacturer WYS represents high-quality pin dust seals for hinge bolts and articulated joints. Their construction combines a sealing element integrated into a metal outer case for maximum press-fit stability in the installation housing. Their primary function is to isolate and protect articulated joints from dust, mud, water, sand, and various environmental solid particles. Engineered for environments with extreme dust conditions, these wipers significantly increase equipment durability and operational lifespan. The specific profile relief allows for easy discharge of used and contaminated grease when injecting new lubricant under pressure, while the integrated metal ring protects the delicate polyurethane lip from aggressive external impacts, such as stones or hard debris.VAW seals are mainly used in heavy industry—such as construction and mining machinery—acting as OEM or alternative spare parts for equipment from leading construction machinery and industrial facility manufacturers.
