Bushings carry the side load in a damper or fork and keep the moving parts concentric. A worn bushing lets the shaft move off centre, and the seal is the next thing to fail. Both diameters and the length are specification rather than approximation.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eÖhlins publishes dimensions for its service parts so a workshop can verify before it fits. Öhlins manufactures service parts on the same lines as production parts — there is no second quality. Order by part number — descriptions repeat across sizes, numbers do not. Where a number has been superseded, Öhlins states the replacement — we pass that on.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003e21663-03 is the Öhlins number for this position — the same one printed in the service documentation. The published dimensions are inner diameter 12 mm, outer diameter 230 mm, length 25 mm — measure the old part against them if you are unsure. Guides and sleeves set the internal alignment of a cartridge. Both diameters and the length are specification, not approximation.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eÖhlins recommends that its units are serviced by an authorised centre. We are one: rebuild, revalve and setup all happen in our own workshop.\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 21663-03\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 12 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 230 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 25 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":53652712521994,"sku":"21663-03","price":6.29,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21663-03_1101d1d5-4d47-44cf-a72c-c6b67d433bab.png?v=1788879973","url":"https:\/\/inter-pace.com\/products\/ohlins-guide-sleeve-12-230-25-21663-03","provider":"Inter-Pace","version":"1.0","type":"link"}
