  • Radial 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:

    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
