O-ring seals are usually used in static sealing applications. Under some circumstances they are applied in dynamic sealing. The project introduced here is about O-ring seals in oscillating rotation combined with an axial load. The insufficent durability of some seals at the blade bearing in controllable propellers is the reason this project was initiated.

The seal is placed between two plates. The seals are exposed to a constant axial force, so they are able to creep. During the experiment the torque, the angle of rotation, the distance between the plates, the temperature near the sealing zone, and the temperature in the laboratory are measured. Variations concerning load, sealing material and lubrication (oil, grease, water, no lubricant, and their combinations), and relative velocity are verified. The test range is up to 400 000 oscillations.

The paper presents the results and some hypotheses for modeling system of friction and wear, especially the influence of lubrication, time and material of the seal.
