6. Ensure that the oil seal solidifies
Common causes of oil seal failure
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).

Oil seals are used in a great many machines.
4. The sealing function of the oil seal is good and the service life is long. It has the certain adaptability to the vibration of the machine and eccentricity of the main shaft.
ERIKS type R (type A according to the DIN standard) is identical in shape to type M, but has a rubber outer case with metal reinforcement on the inside. The rubber creates a good seal in the housing, even if the housing has suffered minor damage or is not in its best condition for other reasons. The RST version has a dust lip. These types are often chosen to replace a type with a metal outer case because they are easier to install and can cope with minor damage to the groove, such as scratches.
By first finding out the dimensions of the inner and outer diameters and the height of the bore, you have all the data for the correct size of the oil seal. Of course, the oil seal must also be able to withstand the pressure, temperature and medium it is exposed to within the seal during the manufacturing process. You can read more about this in our oil seal selection guide.
Oil leak: the most frequent failure of the oil seal
Automotive rubber gaskets are widely used in various vehicle systems for their flexibility, resilience, and sealing properties. These gaskets are employed in applications such as engines, transmissions, and exhaust systems, providing reliable sealing solutions to prevent fluid or gas leakage. The versatility and durability of automotive rubber gaskets make them essential components in maintaining the integrity and efficiency of vehicle systems.
The basic principle of sealing is straightforward – the flexible lip is held against the rotating part (usually the shaft) whilst the casing (or O.D.) is pressed into the housing or bore and holds the seal in place. The sealing lip needs some form of lubrication to avoid overheating and is usually energized by means of a garter spring.
