Shim thickness is measured in hundredths of a millimetre because that is the resolution at which damping force changes.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eThickness 0.20 mm\u003c\/li\u003e\n\u003cli\u003eOuter Diameter 21 mm\u003c\/li\u003e\n\u003cli\u003eInner Diameter 12 mm\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00520-21\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat It Is\u003c\/h2\u003e\u003cp\u003eÖhlins publishes 12 mm, 21 mm, 0.20 mm for 00520-21 — the dimensions are the identity of the part. Two shims of the same thickness but different diameter give completely different curves. Shims are reused only if they are undamaged and flat; a coned shim is finished. Öhlins stamps and grinds its shims to tolerances a general-purpose washer never holds.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eBuying the individual part rather than a complete assembly is what makes servicing an Öhlins unit worthwhile. Öhlins is one of the few suspension makers that still supplies every position in the exploded view as a single part. If you are between two sizes, send us the measurement and we will check it against the catalogue. For a full rebuild, the seal kit plus the wear parts is usually the sensible order.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eOrder under 00520-21. Where several sizes share a description, only the number separates them. Öhlins states inner diameter 12 mm, outer diameter 21 mm, thickness 0.20 mm for this number, and those figures are the deciding ones. Face flatness matters as much as thickness — a shim that does not seal against its neighbour leaks damping. A worn or bent shim shows up as damping that has quietly drifted from the setting sheet.\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 00520-21\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Shims\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 21 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThickness:\u003c\/em\u003e 0.20 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":53646906392842,"sku":"00520-21","price":6000.0,"currency_code":"TZS","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00520-21_abaa848b-4078-4937-99f7-aa9521655f77.png?v=1788869497","url":"https:\/\/inter-pace.com\/en-tz\/products\/ohlins-shims-12-21-0-20-00520-21","provider":"Inter-Pace","version":"1.0","type":"link"}
