DescriptionThe whole story▼
Seal head 16/46/21.5, Öhlins part number 05280-01. Seals are the part of a damper that decides whether it holds its gas charge and its oil, and they are the usual reason a unit ends up on the bench.

Function
This one measures 16 mm, 46 mm, 21.5 mm, and those figures are what separate it from the neighbouring numbers. Öhlins uses seals with a spring-loaded lip so they follow the shaft as it wears. Replacing seals at service intervals is far cheaper than replacing what a failed seal damages. Head diameter and thread are specific to the tube it closes.
Genuine Service Part
The tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. Öhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. Where a number has been superseded, Öhlins states the replacement — we pass that on. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson.
Identifying the Right Part
Part number 05280-01 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. The published dimensions are inner diameter 16 mm, outer diameter 46 mm, thickness 21.5 mm — measure the old part against them if you are unsure. Replacing seals at service intervals is far cheaper than replacing what a failed seal damages. Head diameter and thread are specific to the tube it closes.
Fitting and Setup Service
We 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.
