The cylinder tube is the working bore: the piston runs inside it and every damping force is reacted by its wall.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eÖhlins part number 05643-03\u003c\/li\u003e\n\u003cli\u003eDiameter 31 mm\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eLength 69 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFunction\u003c\/h2\u003e\u003cp\u003eThis one measures 31 mm, 69 mm, and those figures are what separate it from the neighbouring numbers. Surface finish is specified in microns, because it decides how quickly the piston band wears. Corrosion inside a tube is terminal: it cannot be honed out without changing the clearance. The tube is what the whole damper is built around: everything else references its bore.\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 numbers every position so a workshop can order precisely what it needs, not a whole assembly. Where a number has been superseded, Öhlins states the replacement — we pass that on. We can check the number against the Öhlins exploded view before you order — just ask.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003ePart number 05643-03 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Check diameter 31 mm, length 69 mm against what you have removed; a close size is not the same part. The cylinder is one of the few damper parts that is genuinely wear-limited. A hard bottoming often leaves a witness ring inside the bore — that tube is finished.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eWe are an authorised Öhlins service centre, so you do not have to source the tools and the nitrogen: send us the damper and we rebuild it with the correct parts and the correct setting.\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 05643-03\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Cylinder Tubes\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDiameter:\u003c\/em\u003e 31 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 69 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":53649969447178,"sku":"05643-03","price":128.29,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/05643-03_f156b73b-5975-4f73-981b-c8a79af1bf96.png?v=1788876929","url":"https:\/\/inter-pace.com\/products\/ohlins-pds-damping-cylinder-31-69-05643-03","provider":"Inter-Pace","version":"1.0","type":"link"}
