Where It Sits

05129-12 is the 46 mm, 16 mm version — Öhlins lists each size separately. 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. Cross-section is as important as diameter: an O-ring that is too thin will not seal at pressure. Assembly grease matters — the wrong compound swells the seal and it fails early.

Genuine Service Part

Every part in this catalogue is one Öhlins fits itself during assembly and service. Buying the individual part rather than a complete assembly is what makes servicing an Öhlins unit worthwhile. Order by part number — descriptions repeat across sizes, numbers do not. We can supply the whole position from the drawing rather than the single piece if that is easier.

How to Be Sure It Fits

Öhlins identifies this position by the number 05129-12 in the exploded view for the unit it belongs to. inner diameter 46 mm, outer diameter 16 mm is what distinguishes this number from its neighbours in the range. A seal that has taken a set no longer springs back and starts to weep. Static seals and dynamic seals are not interchangeable even in the same size.

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.
