Bushings carry the side load in a damper or fork and keep the moving parts concentric. Both diameters and the length are specification rather than approximation. Öhlins uses low-friction coated bushings so the unit breaks away smoothly rather than sticking.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. Öhlins publishes dimensions for its service parts so a workshop can verify before it fits. Order by part number — descriptions repeat across sizes, numbers do not. Service parts are ordered per piece unless stated otherwise.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 21804-02 in the exploded view for the unit it belongs to. The published dimensions are inner diameter 8.1 mm, outer diameter 44.2 mm, length 175 mm — measure the old part against them if you are unsure. Bushings take the side load so the seal only has to seal. A worn guide shows up as a knock over sharp edges.\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 21804-02\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Guides\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 8.1 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 44.2 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 175 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":53652861026570,"sku":"21804-02","price":144.65,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21804-02_8555219a-bc13-40f7-939f-3d1e2ad1d70c.png?v=1788880259","url":"https:\/\/inter-pace.com\/products\/ohlins-guide-sleeve-internal-8-1-44-2-175-21804-02","provider":"Inter-Pace","version":"1.0","type":"link"}
