In addition to the entire range of shapes and dimensions of radial shaft seals according to DIN 3760/3761, Hänssler also supplies all types of axial shaft seals (chevron set) as well as shaft protection sleeves. We manufacture seals for rotary or swivel movements for rotary distributors, swivel drives, hydraulic motors and tool spindles of any kind.
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 – everything from one source!
Profiles according to customer preferences
If you have conditions which cannot be optimally solved with a standard profile, we can also manufacture an ideal wiper system according to customers’ drawings or develop one. In this field we are a development partner and are perfectly equipped to design the ideal product for you.
