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 further information are listed in the following categories:
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 ideal material, the following criteria are important:
Numerous applications can not be sealed with rotary shaft seals. The applications listed below require special rotary seals.
Pressure range: | up to 200 bar |
Sliding speeds: | up to 30 m/s |
Temperature range: | -55 to +220 °C (depending on material) |
Rotary seals with leader elements made of elastomer
Rotary seals with a preload element consist of an outer ring made, for example, of PTFE, PTFE compound, PE, PU, PA and an O-ring or rectangular ring. The outer rings are usually turned parts and can therefore be manufactured in a very wide range of dimensions.
Pressure range: | up to 300 bar |
Sliding speeds: | up to 2 m/s |
Temperature range: | -55 to +200 °C (depending on material) |
