Play at the bushing shows up as a knock over sharp bumps. Öhlins uses low-friction coated bushings so the unit breaks away smoothly rather than sticking. Öhlins uses PTFE-coated bushings for a low breakaway force.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eÖhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. Buying the individual part rather than a complete assembly is what makes servicing an Öhlins unit worthwhile. Öhlins parts are unit-specific: a close dimension is not a substitute. We can check the number against the Öhlins exploded view before you order — just ask.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eOrder under 21806-01. Where several sizes share a description, only the number separates them. The published dimensions are inner diameter 25.3 mm, outer diameter 34.5 mm, length 12 mm — measure the old part against them if you are unsure. A worn bushing lets the shaft move off centre, and the seal is the next thing to fail. A worn guide shows up as a knock over sharp edges.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eA damper rebuild is workshop work: it needs the unit dismantled, the shim stack rebuilt in the correct order and the gas charge reset. We are an authorised Öhlins service centre and do exactly that in house — send us the unit or ask us to fit the part with your order.\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 21806-01\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 25.3 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 34.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 12 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":53652861714698,"sku":"21806-01","price":32.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21806-01_1b77eac7-9bba-4bcc-82fb-87240d26a46d.png?v=1788880262","url":"https:\/\/inter-pace.com\/products\/ohlins-guide-ring-25-3-34-5-12-21806-01","provider":"Inter-Pace","version":"1.0","type":"link"}
