Dust seals keep grit off the running surface; once they are torn, the oil seal behind them has a short life. Cross-section is as important as diameter: an O-ring that is too thin will not seal at pressure. The dust seal does the hard work: it keeps the grit that would score the shaft away from the oil seal.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eRebuilding to specification only works if the parts are to specification — that starts here. Öhlins publishes dimensions for its service parts so a workshop can verify before it fits. We can supply the whole position from the drawing rather than the single piece if that is easier. Öhlins parts are unit-specific: a close dimension is not a substitute.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003ePart number 21025-06 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. inner diameter 14 mm, outer diameter 36 mm is what distinguishes this number from its neighbours in the range. An oil seal that has hardened lets the shaft pass oil past it, and the damping fades long before the leak becomes visible. A seal head combines the oil seal, the dust seal and the shaft bushing in one serviceable assembly.\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 21025-06\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Seal Heads\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 14 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 36 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":53649968103690,"sku":"21025-06","price":10300.0,"currency_code":"BDT","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21025-06_f961e750-1fb1-4dd7-af29-68eed74ce399.png?v=1788876906","url":"https:\/\/inter-pace.com\/en-bd\/products\/ohlins-seal-head-assy-14-36-21025-06","provider":"Inter-Pace","version":"1.0","type":"link"}
