Aluminium tubes are hard-anodised in the bore so the piston band has a hard surface to run against.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDiameter 46 mm\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eLength 52 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 05221-01\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFunction\u003c\/h2\u003e\u003cp\u003eAt 46 mm, 52 mm it fits one position only; the next size up carries a different number. The tube is what the whole damper is built around: everything else references its bore. Surface finish is specified in microns, because it decides how quickly the piston band wears. The cylinder tube is the working bore of the damper: the piston runs in it, and its finish decides how well the piston rings seal.\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. Öhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. Service parts are ordered per piece unless stated otherwise. 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\u003eÖhlins identifies this position by the number 05221-01 in the exploded view for the unit it belongs to. Öhlins states diameter 46 mm, length 52 mm for this number, and those figures are the deciding ones. The cylinder tube is the working bore of the damper: the piston runs in it, and its finish decides how well the piston rings seal. Corrosion inside a tube is terminal: it cannot be honed out without changing the clearance.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eIf you would rather not open the damper yourself, we can do it — we are an authorised Öhlins service centre and rebuild these units as a matter of routine.\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 05221-01\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 46 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 52 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":53649757045002,"sku":"05221-01","price":130.19,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/05221-01_c5bbe685-1b6e-443d-94a6-5f8147dd7daf.png?v=1788876464","url":"https:\/\/inter-pace.com\/products\/ohlins-cylinder-tube-46-52-239-05221-01","provider":"Inter-Pace","version":"1.0","type":"link"}
