It is part of the Trailer Hubs \u0026amp; Bearings product line and is built to keep the hub cavity sealed against water, dirt, and road debris while retaining the lubricant that protects the wheel bearings inside. A properly fitted wheel seal is one of the most important components in a trailer hub assembly: it prevents grease from leaking out and contaminants from working their way in, both of which are common causes of premature bearing failure on boat trailers, utility trailers, and other towed equipment. The SL-225-1 seal weighs 1 pound as packaged. Because the exact bore, shaft, and hub dimensions of a wheel seal must match the hub it is installed in, confirm that the 3.371 inch size matches your hub or bearing specification before ordering. This seal is sold as a standalone replacement part for hub servicing and bearing repacking jobs.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Reliable Bearings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e SL-225-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Trailer Hubs \u0026amp; Bearings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 3.371 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Reliable Bearings SL-225-1?\u003c\/strong\u003e The SL-225-1 is a Reliable Bearings wheel seal sized at 3.371 inches, made for trailer hub and bearing assemblies.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does the 3.371 in the part name refer to?\u003c\/strong\u003e It is the size designation for the Reliable Bearings SL-225-1 wheel seal; confirm it matches your hub's seal specification before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this seal fit my trailer hub?\u003c\/strong\u003e Fitment depends on matching the 3.371 inch size of the SL-225-1 to your hub's seal bore; check your hub or bearing kit specification to confirm compatibility.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the SL-225-1 wheel seal weigh?\u003c\/strong\u003e The Reliable Bearings SL-225-1 wheel seal weighs 1 pound.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category of part is the SL-225-1?\u003c\/strong\u003e It is listed under Trailer Hubs \u0026amp; Bearings, as it is a wheel seal used in trailer hub servicing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the SL-225-1 a genuine Reliable Bearings part?\u003c\/strong\u003e Yes, the SL-225-1 is a Reliable Bearings branded wheel seal, not a generic substitute.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen would I need to replace a trailer wheel seal like the SL-225-1?\u003c\/strong\u003e A wheel seal such as the SL-225-1 is typically replaced during hub servicing or bearing repacking, or when the existing seal shows signs of grease leakage or wear.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the SL-225-1 come with bearings included?\u003c\/strong\u003e The SL-225-1 is the wheel seal itself; it is sold as a standalone seal for trailer hub assemblies.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the purpose of a wheel seal like the SL-225-1 in a trailer hub?\u003c\/strong\u003e A wheel seal such as the SL-225-1 keeps grease inside the hub cavity and keeps water and debris out, protecting the wheel bearings from contamination.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the SL-225-1 sold individually?\u003c\/strong\u003e The SL-225-1 is a single wheel seal part; check the listing quantity for how many are included per order.\u003c\/p\u003e","brand":"Reliable Bearings","offers":[{"title":"Default Title","offer_id":49031302643931,"sku":"REL-SL-225-1","price":3.35,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/i_eae96459-172d-4e40-9a73-cebe6b483a51.jpg?v=1785348746","url":"https:\/\/www.goodvibesmarina.com\/products\/reliable-bearings-wheel-seal-sl-225-1-3-371-inch-trailer-hub-bearing-seal","provider":"Good Vibes Marina","version":"1.0","type":"link"}
