The dust seal does the hard work: it keeps the grit that would score the shaft away from the oil seal. Assembly grease matters — the wrong compound swells the seal and it fails early. Dust seals keep grit off the running surface; once they are torn, the oil seal behind them has a short life.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eThis is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. Öhlins lists this part under its own number in the service catalogue so a workshop can order exactly what it needs. We can supply the whole position from the drawing rather than the single piece if that is easier. If the unit is already apart, compare the published dimensions with the part in your hand.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eOrder under 15561-01. Where several sizes share a description, only the number separates them. The thread is M28x1. An oil seal that has hardened lets the shaft pass oil past it, and the damping fades long before the leak becomes visible. Assembly grease matters — the wrong compound swells the seal and it fails early.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eFitting service parts means opening a pressurised unit. As an authorised Öhlins service centre we do that here, with the right tools and a dyno check afterwards — just ask.\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 15561-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Seals\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThread:\u003c\/em\u003e M28x1\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":53652416659722,"sku":"15561-01","price":36.55,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/15561-01_8615ca05-a2ee-48e7-a3b1-bd85f60f9265.png?v=1788879082","url":"https:\/\/inter-pace.com\/products\/ohlins-seal-nut-m28x1-15561-01","provider":"Inter-Pace","version":"1.0","type":"link"}
