HSR

Seals are particular exposed to pressure, friction and temperature. Our aim is to design and make seals or sealing systems that perform optimal for all these parameters. Following from these parameters is wear, extrusion etc. Our materials are low friction and wear resistant. When applying the right surface parameters in combination with seal type and materials, we are able to supply a very wear and extrusion resistant sealing system for almost all applications.

Below you can find an overview of sealing and bearing materials. Please select the suitable material for your application. When you have any difficulties with selection of a material, contact your AST representative.

Sealing surfaces are very much known for influencing the wear, extrusion and the leakage rate for a sealing system. When applying our sealing systems, please follow our specifications.  You will find these specifications through the schedule below.

HSR is a High Speed Rotary seal. This seal is in several models with different functions available. It is normally made with a stainless steel housing and at least one PTFE compounded lip. Due to the low friction and the stiffness of this lip, it can be applied for high surface speeds and relatively high pressures. It can be made for DIN 3660 grooves of normal oil seals but also in almost every special dimension you need.

Please ask your AST representative for information before selecting a sealtype and compounds.
