Based on this and building on the extensive experience gained at Siemens * and other FVA member companies, brief descriptions, required measures and notes on this subject are summarised in the following overview. Table 1: Notes on the leak tightness of radial shaft sealing rings (RWDR ) Condition Description Measures Notes Leaktight, dry No moisture to be seen on radial shaft sealing ring.None Leaktight, damp Film of moisture formedfunctionally in the area of the sealing edge but notextending beyond thebottom side of the radialshaft sealing ring.Only if dirt adheres, clean below the sealing lip with clean rag. The sealing lip must not be soiled. Monitor.The radial shaft sealing ring often dries by itself in further operation. No reason for complaint. Leaktight, wet Moisture film extending beyond the bottom side of the radial shaft sealingring but not dripping.Clean below the sealing lip with clean rag. The sealing lip must not be soiled. Monitor.The radial shaft sealing ring often dries by itself in further operation. No reason for complaint. Measurable leak Small trickle to be seen on the bottom side of the radial shaft sealing ring,dripping.Replace radial shaft sealing ring if necessary; identify possible cause ofradial shaft sealing ringfailure and rectify.May be reason for complaint; one drop of oil day is acceptable. Short-term leak Short-term failure of the sealing system.Clean below the sealinglip with clean rag. The sealing lip must not be soiled.
