Normal environmental stress

Standard seal

High-quality NBR radial shaft sealing ring with dust protection lip.

Environment with low dust and pollution levels with low moisture.

Longer service life

Seal with longer service life

The radial shaft sealing ring with protective lip is designed with an additional seal on the internal gearbox side.

The sealing system has a high degree of reliability due to its resistance to impurities in the oil.

Environment with low dust and pollution levels with low moisture.

Longer service life and increased environmental stress

Seal for increased environmental stress

This seal is equipped with an additional fiber disk. In addition to the longer service life, it also provides increased protection against higher environmental stress as a result of dust and dirt deposits. As a  consequence, the sealing system has a high degree of reliability.

For additional environmental stress, e.g. water jets or significant levels of pollution as a result of production materials, please contact your local Siemens office.

Environments with increased pollution and dust levels as well as low  moisture.

Typical applications:

Production areas with increased pollution and dust, such as wood chips, dusts or granulate as well as occasional spray water.
