A seal that has taken a set no longer springs back and starts to weep. A leaking damper is not a cosmetic problem: it is a damper that has stopped controlling the wheel. Öhlins uses seals with a spring-loaded lip so they follow the shaft as it wears.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eThis is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. The part is identical to what Öhlins fits in production — same supplier, same specification. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson. Service parts are ordered per piece unless stated otherwise.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003e21920-01 is the Öhlins number for this position — the same one printed in the service documentation. inner diameter 10 mm, outer diameter 36.4 mm, thickness 68 mm is what distinguishes this number from its neighbours in the range. Öhlins uses seals with a spring-loaded lip so they follow the shaft as it wears. Static seals and dynamic seals are not interchangeable even in the same size.\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 21920-01\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 10 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 36.4 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThickness:\u003c\/em\u003e 68 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":53652070465802,"sku":"21920-01","price":1016.0,"currency_code":"SAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21920-01_eccfe34e-4862-4bca-8882-2fc5ffae08a4.png?v=1788878041","url":"https:\/\/inter-pace.com\/en-sa\/products\/ohlins-seal-head-10-36-4-68-21920-01","provider":"Inter-Pace","version":"1.0","type":"link"}
