This is a common failure point on boat trailers and utility trailers that see regular submersion during boat launching and retrieval, making a properly sized, snug-fitting seal an important part of routine hub maintenance. The SL-173 is built to a 2.569 inch outer diameter, 1.719 inch inner diameter, and 0.500 inch width, so it is intended for hub bores and spindles matching those exact dimensions. Installing a wheel seal that does not match these measurements can allow grease to leak out or water to work its way into the bearing race, leading to premature bearing wear or failure. This seal falls in the Trailer Hubs and Bearings category and is typically replaced any time hub bearings are repacked or replaced, or whenever a seal shows signs of cracking, hardening, or leaking grease. Confirm your hub's OD, ID, and width against the SL-173 specifications below before ordering to make sure it is the correct seal for your application.\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-173\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Wheel Seal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter:\u003c\/strong\u003e 2.569 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Diameter:\u003c\/strong\u003e 1.719 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 0.500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Trailer Hubs and Bearings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the Reliable Bearings SL-173 wheel seal?\u003c\/strong\u003e The SL-173 measures 2.569 inches outer diameter, 1.719 inches inner diameter, and 0.500 inches in width.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the SL-173 wheel seal used for?\u003c\/strong\u003e It is used to seal trailer hub and bearing assemblies, keeping grease in and water and debris out, which falls under the Trailer Hubs and Bearings category.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the SL-173 wheel seal weigh?\u003c\/strong\u003e 1 pound is the weight of the Reliable Bearings SL-173 wheel seal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the SL-173 fit my trailer hub?\u003c\/strong\u003e Fit depends on matching your hub's exact bore and spindle dimensions to the SL-173 specifications of 2.569 inches OD, 1.719 inches ID, and 0.500 inches width; measure your hub before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should I replace a trailer wheel seal like the SL-173?\u003c\/strong\u003e Replace it any time you repack or replace hub bearings, or as soon as a seal shows cracking, hardening, or grease leakage, since a worn seal lets water into the bearing race.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the SL-173 a genuine Reliable Bearings part?\u003c\/strong\u003e Yes, SL-173 is the manufacturer part number for this Reliable Bearings wheel seal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order the SL-173?\u003c\/strong\u003e An order of the Reliable Bearings SL-173 includes one wheel seal sized at 2.569 inches OD by 1.719 inches ID by 0.500 inches width.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan boat trailer hubs use the SL-173 wheel seal?\u003c\/strong\u003e Yes, this seal is listed under the Trailer Hubs and Bearings category, which covers boat trailer hub applications where the dimensions match.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if my old seal matches the SL-173 dimensions?\u003c\/strong\u003e Measure the outer diameter, inner diameter, and width of the seal you are removing and compare them to the SL-173 specifications of 2.569 inches OD, 1.719 inches ID, and 0.500 inches width.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the SL-173 come with grease or other hub hardware?\u003c\/strong\u003e No, the SL-173 is the wheel seal only; it does not include grease, bearings, or other hub hardware.\u003c\/p\u003e","brand":"Reliable Bearings","offers":[{"title":"Default Title","offer_id":49031302545627,"sku":"REL-SL-173","price":3.64,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/i_7f4666dd-82e9-4d37-80da-e24fb5df5af5.jpg?v=1785348736","url":"https:\/\/www.goodvibesmarina.com\/products\/reliable-bearings-wheel-seal-sl-173-2-569-inch-od-x-1-719-inch-id-x-0-500-inch-width-for-trailer-hubs-and-bearings","provider":"Good Vibes Marina","version":"1.0","type":"link"}
