Twin-tube dampers carry two concentric tubes and list them separately. Wall thickness and bore finish are what let a cylinder hold pressure without deforming under load. 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\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eEvery part in this catalogue is one Öhlins fits itself during assembly and service. Öhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. If the unit is already apart, compare the published dimensions with the part in your hand. The exploded drawing for your unit names the number; if you do not have it, we do.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eOrder under 21722-01. Where several sizes share a description, only the number separates them. This position has no published dimension, so the part number is the only reliable identifier. Diameter and length together identify the tube — both are specific to the damper it came from. Wall thickness and bore finish are what let a cylinder hold pressure without deforming under load.\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 21722-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Cylinder Tubes\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":53652800733450,"sku":"21722-01","price":608.0,"currency_code":"PGK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21722-01_e420f8b4-4897-42b4-ba73-216b8ee80f59.png?v=1788880144","url":"https:\/\/inter-pace.com\/en-pg\/products\/ohlins-hydraulic-cylinder-21-21722-01","provider":"Inter-Pace","version":"1.0","type":"link"}
