Öhlins uses seals with a spring-loaded lip so they follow the shaft as it wears. O-ring sizes are given as inner diameter and cross-section, and both have to match — a close size is not a match. Öhlins builds the head so the dust seal takes the grit before it reaches the oil seal.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eEvery part in this catalogue is one Öhlins fits itself during assembly and service. The tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. Öhlins parts are unit-specific: a close dimension is not a substitute. For a full rebuild, the seal kit plus the wear parts is usually the sensible order.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003ePart number 21766-01 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Check inner diameter 10 mm, outer diameter 29 mm, thickness 19 mm against what you have removed; a close size is not the same part. A seal head combines the oil seal, the dust seal and the shaft bushing in one serviceable assembly. O-ring sizes are given as inner diameter and cross-section, and both have to match — a close size is not a match.\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 21766-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Seal Heads\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 10 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 29 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThickness:\u003c\/em\u003e 19 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":53651631309066,"sku":"21766-01","price":911.21,"currency_code":"CZK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21766-01_d0e69383-ee35-4dca-81a1-2e06a3383d6f.png?v=1788877804","url":"https:\/\/inter-pace.com\/en-cz\/products\/ohlins-seal-head-10-29-19-21766-01","provider":"Inter-Pace","version":"1.0","type":"link"}
