Radial shaft seals / shaft seals

In addition to the complete range of shapes and dimensions of radial shaft seals according to DIN 3760/3761, we also supply all designs of axial shaft seals (V-rings) as well as shaft sleeves. Seals for rotary distributors, rotary actuators, hydraulic motors and tool spindles of all types are manufactured for rotary / swivel movements.

Standard profiles

The standard profiles shown below are seals that represent the state of the art. We manufacture these standard seals in-house or supply them as moulded parts from approved partners for all required groove dimensions in a variety of materials.

Depending on the quantity, the material and your requirements, we will offer you seals in the appropriate manufacturing process.

A general overview and more information about them are listed in the following categories:

radial shaft seals

Choosing the correct profile

The more information is known, the better a sealing system can be adapted to a specific application.

To choose the right profile and the optimal material, the following criteria are important:

installation space
double-acting or single-acting
pressure range
temperature range
medium
rotation / swivel speed
counterface
mounting possibility
friction behavior
tightness
service life expectancy
price
availability

shaft seal
DR 101

Radial shaft seal according to DIN 3760 e.g. type A or AS. Many dimensions in all conceivable designs available from stock. For special dimensions/applications, it may be necessary to produce a radial shaft seal by machining. Instead of a vulcanized metallic ring, for example, a preload ring made of POM is used.
