Öhlins recommends replacing seals whenever the unit is opened, not only when it leaks.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOuter Diameter 30 mm\u003c\/li\u003e\n\u003cli\u003eInner Diameter 48.8 mm\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 15551-01\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFunction\u003c\/h2\u003e\u003cp\u003eThis one measures 48.8 mm, 30 mm, and those figures are what separate it from the neighbouring numbers. Seal heads combine the oil seal, the dust seal and the bushing in one assembly. Replacing seals at service intervals is far cheaper than replacing what a failed seal damages. Öhlins specifies seal compounds for temperature stability rather than for the lowest unit cost.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eSuspension is one of the few areas where the original part is genuinely the cheaper decision. Rebuilding to specification only works if the parts are to specification — that starts here. Service parts are ordered per piece unless stated otherwise. We can check the number against the Öhlins exploded view before you order — just ask.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 15551-01 in the exploded view for the unit it belongs to. The published dimensions are inner diameter 48.8 mm, outer diameter 30 mm — measure the old part against them if you are unsure. Dust seals keep grit off the running surface; once they are torn, the oil seal behind them has a short life. Öhlins uses seals with a spring-loaded lip so they follow the shaft as it wears.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eAsk us about a full service: as an authorised Öhlins centre we strip, inspect, replace what is worn and set the unit back to its specification.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eBrand:\u003c\/em\u003e Öhlins\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003ePart Number:\u003c\/em\u003e 15551-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Sealing Washers\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 48.8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 30 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCountry of Origin:\u003c\/em\u003e Sweden\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Öhlins","offers":[{"title":"Default Title","offer_id":53649783521546,"sku":"15551-01","price":11.44,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/15551-01_faede5ee-7787-4eeb-b17c-3542c2150ff0.png?v=1788876608","url":"https:\/\/inter-pace.com\/products\/ohlins-seal-washer-48-8-30-15551-01","provider":"Inter-Pace","version":"1.0","type":"link"}
