Among the most common causes of oil seal failure are:
ERIKS type GV (type C according to DIN) is equivalent to type M, but is a heavy-duty version with a double metal casing. This can be a useful solution with larger diameters in more demanding applications. There is also a version of this type with a dust lip; the GVST (type CS according to DIN).
If these criteria are met, damage of the machine can be reduced, the time needed to replace the oil seals when performing repairs can be shortened, and the machine can be used for a longer period of time.

Types of oil seals include:



When the total eccentricity is excessive, the sealing edge of the seal lip cannot accommodate shaft motions and leakage may occur.
Total eccentricity is the sum of shaft runout and the housing-bore eccentricity.
Total eccentricity, shaft runout and housing-bore eccentricity are generally expressed in TIR (Total Indicator Reading).
Overall, black spark plugs are a common issue that can occur in internal combustion engines. It is important to regularly inspect and replace spark plugs to ensure optimal engine performance and prevent more serious issues down the line. By addressing the root causes of black spark plugs, such as a rich air-fuel mixture, oil leakage, and overheating, you can keep your engine running smoothly and efficiently.
Operating conditions such as the engine’s temperature, position, size, pressure and shaft speed largely determine which individual oil seal composition is most suitable for every individual application.
