Lip seals of this type form a flexible contact barrier between a rotating shaft and a stationary housing bore, keeping grease or oil contained while blocking dirt, moisture, and debris from entering the bearing cavity. This seal measures 0.375 inches inner diameter, 0.75 inches outer diameter, and 0.25 inches in width. It is an OEM replacement part sourced directly through Ariens, making it appropriate for service technicians performing drivetrain or gearbox maintenance on Ariens-branded outdoor power equipment.\u003c\/p\u003e\n\u003cp\u003eThis lip seal is used in residential lawn and garden applications where rotating shafts pass through housings in drive systems, gearboxes, or wheel axle assemblies. Installers servicing Ariens walk-behind mowers, zero-turn mowers, tillers, or similar equipment will encounter this seal during gear case rebuilds or when addressing lubricant leaks. Proper fitment depends on matching all three dimensions precisely to the housing bore and shaft diameter in the assembly being serviced.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInner diameter of 0.375 inches fits standard small-shaft gearbox and drivetrain applications\u003c\/li\u003e\n  \u003cli\u003eOuter diameter of 0.75 inches for positive press-fit into the mating housing bore\u003c\/li\u003e\n  \u003cli\u003eWidth of 0.25 inches for compact installation in shallow seal pockets\u003c\/li\u003e\n  \u003cli\u003eOEM Ariens part number ensures correct dimensional and material match for factory-specified fitment\u003c\/li\u003e\n  \u003cli\u003eLip seal design provides a dynamic sealing surface against rotating shafts to retain lubricant and exclude contaminants\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement lip seal for Ariens lawn and garden power equipment requiring a 0.375 inch bore, 0.75 inch outer diameter, 0.25 inch width seal.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this lip seal is typically performed by small engine or outdoor power equipment technicians during gearbox or drivetrain service. Before removal of any housing or gear case cover, disconnect the spark plug wire and drain or contain any lubricant present in the assembly. Press the seal squarely into the housing bore using an appropriately sized driver or socket that contacts the outer diameter only — never press on the lip or spring element, as this will damage the sealing surface. Verify shaft surface condition before installation, as a scored or pitted shaft will compromise seal life regardless of seal quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Type\u003c\/strong\u003e: Lip Seal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ARIENS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 21543845\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARIENS","offers":[{"title":"Default Title","offer_id":51161668518194,"sku":"21543845","price":18.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/306260018.png?v=1778878644","url":"https:\/\/voomisupply.com\/products\/ariens-21543845-lip-seal-0-375-x-0-75-x-0-25-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
