They are engineered to facilitate the smooth operation of your equipment, serving as a barrier to prevent the leakage of oils and greases while also keeping foreign substances from entering. SM type seals are used often in larger shaft sizes or when a smaller shaft requires extra strength. This is due to the metal-cased outside diameter which has a very stable construction and offers a better-protected sealing member in comparison to the open-backed style. The SM type oil seals feature a lead-in chamfer and have an additional inner rubber lining particularly fit for protecting the case from erosive fluid. The SM features a single-sealing nitrile rubber lip on the inside diameter. The SM types feature a garter spring which allows some give to prevent a build-up of friction.\u003cfont color=\"red\"\u003e (Seals under 5mm width may not always feature a spring.)\u003c\/font\u003e \u003cbr\u003e\n  \u003cstrong\u003eBenefits: \u003c\/strong\u003eExcellent wear resistance, good running properties, high resistance to chemicals and petroleum-based fuels including petrol, diesel and LPG.\n\u003c\/p\u003e\n","brand":"NAK","offers":[{"title":"Default Title","offer_id":52066676965717,"sku":"17x40x9\/10_SMSS_NAK","price":6.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0979\/1491\/3109\/files\/nak_metal_pack1_6cff96c7-1ff8-4bc7-930f-de4947c9f23b.jpg?v=1780561831","url":"https:\/\/simplybearings.us\/products\/17x40x9-10-smss-nak","provider":"Simply Bearings Ltd - Ball Bearings, Oil Seals, O-rings, V-Belts, SKF","version":"1.0","type":"link"}
