It is intended for use in trailer hub and bearing assemblies as part of routine bearing service or hub repack, sitting behind the inner wheel bearing to form the barrier between the hub cavity and the outside environment.\u003c\/p\u003e\u003cp\u003eInstalling a wheel seal in the correct size is a critical step whenever a trailer hub is repacked or a wheel bearing is replaced, since a worn, cracked, or incorrectly sized seal is one of the most common causes of grease loss and subsequent bearing failure. The Wheel Seal 1.986 from Reliable Bearings is built to the 1.986 inch dimension called out in its name, making it suited to trailer hub bores that require this specific size.\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-122-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Category:\u003c\/strong\u003e Trailer Hubs and Bearings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Seal Size:\u003c\/strong\u003e 1.986 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 Wheel Seal 1.986 used for?\u003c\/strong\u003e The Wheel Seal 1.986, part number SL-122-1 from Reliable Bearings, is used in trailer hub and wheel bearing assemblies to retain grease inside the hub and keep water and debris out.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size is the SL-122-1 wheel seal?\u003c\/strong\u003e SL-122-1 is sized to a 1.986 inch nominal dimension, as reflected in its Wheel Seal 1.986 product name.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Reliable Bearings SL-122-1 wheel seal weigh?\u003c\/strong\u003e This wheel seal weighs 1 pound.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat product category does SL-122-1 belong to?\u003c\/strong\u003e SL-122-1 is listed under Trailer Hubs and Bearings, reflecting its use as a component in trailer hub assemblies.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should I replace a trailer wheel seal like the SL-122-1?\u003c\/strong\u003e A trailer wheel seal such as the Reliable Bearings SL-122-1 should be replaced any time the hub is opened for bearing service or repack, since reusing an old seal risks grease leakage and bearing damage.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Wheel Seal 1.986 a genuine Reliable Bearings part?\u003c\/strong\u003e Yes, part number SL-122-1 is a Reliable Bearings branded Wheel Seal 1.986.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the SL-122-1 wheel seal come with the wheel bearings included?\u003c\/strong\u003e SL-122-1 is the wheel seal itself; it is a standalone seal component rather than a bundled bearing kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat happens if I install the wrong size wheel seal on my trailer hub?\u003c\/strong\u003e Installing a seal that does not match the hub bore, rather than a correctly sized part like the 1.986 inch SL-122-1, can allow grease to leak out or water to enter, leading to premature bearing failure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the SL-122-1 wheel seal be reused after removing a hub?\u003c\/strong\u003e No, wheel seals such as the SL-122-1 are designed for one-time installation and should be replaced, not reused, once a hub has been disassembled.\u003c\/p\u003e","brand":"Reliable Bearings","offers":[{"title":"Default Title","offer_id":49031302316251,"sku":"REL-SL-122-1","price":2.35,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/i_38f6d0c4-1503-47ab-9713-c13cc608b249.jpg?v=1785348741","url":"https:\/\/www.goodvibesmarina.com\/products\/reliable-bearings-wheel-seal-1-986-trailer-hub-grease-seal-part-number-sl-122-1","provider":"Good Vibes Marina","version":"1.0","type":"link"}
