- Oil leakage is one of the most common issues faced by vehicle owners, and a failing valve cover gasket is often the culprit. When this gasket wears out or deteriorates, it can lead to oil seeping into areas where it doesn't belong. Over time, this can affect the engine's lubrication, reducing its efficiency and potentially leading to more significant damage Over time, this can affect the engine's lubrication, reducing its efficiency and potentially leading to more significant damage

How are they used?
There are several key factors to consider when you are selecting the oil seals for your next project to ensure that you protect your machinery from immediate and long-term damage.

The skeleton oil seal structure consists of three parts: the oil seal body, the reinforced skeleton and the self-tightening coil spring. The sealing body is divided into bottom, waist frame oil seal structure diagram, cutting edge and sealing lip according to different parts. Generally, the inner diameter of the skeleton oil seal in the free state is smaller than the shaft diameter, that is, it has a certain interference. Therefore, after the oil seal is installed on the oil seal seat and the shaft, the pressure of the oil seal edge and the contraction force of the self-tightening coil spring will produce a certain radial tightening force on the shaft. After a period of operation, the pressure will rapidly decrease or even disappear. , Therefore, adding a spring can compensate for the self-tightening force of the oil seal at any time.
Choosing the correct oil seal application
With spring type Secures stable sealing performance.

Scrape off all the traces of dirt and old gasket from the engine and sump flanges with a paint scraper.

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).

The most common oil seals are the ERIKS types R, RST, M and MST, which correspond respectively to types A, AS, B and BS according to DIN 3760/ISO 6194.
Our standard and custom rubber oil seals can match the increasingly demanding applications of any industry.
