Key Features

  • Original Öhlins service part
  • Inner Diameter 46 mm
  • Outer Diameter 16 mm

What It Is

Dimensionally this is 46 mm, 16 mm, which is how it is told apart from the rest of the range. Cross-section is as important as diameter: an O-ring that is too thin will not seal at pressure. The bushing inside carries the side load so the seal only has to seal. A seal head combines the oil seal, the dust seal and the shaft bushing in one serviceable assembly.

Why the Original

Öhlins keeps service parts available for units long after they leave the current price list. The part is identical to what Öhlins fits in production — same supplier, same specification. Öhlins parts are unit-specific: a close dimension is not a substitute. The Öhlins exploded view names the number for each position; we can look it up if you do not have it.

Identifying the Right Part

The reliable route is the exploded drawing: find the position, read the number, order it — 05129-09 in this case. Check inner diameter 46 mm, outer diameter 16 mm against what you have removed; a close size is not the same part. An oil seal that has hardened lets the shaft pass oil past it, and the damping fades long before the leak becomes visible. O-ring sizes are given as inner diameter and cross-section, and both have to match — a close size is not a match.

Fitting and Setup Service

Ask us about a full service: as an authorised Öhlins centre we strip, inspect, replace what is worn and set the unit back to its specification.
