Thermoset Shaft Seals – A new Generation of Radial Shaft Seals

Abstract

Radial shaft seals used in corrosive media need usually a stainless steel support part.To achieve sufficiently good adhesion between the support part and the elastomer, a complex pre-treatment process is required.With radial shaft seals using a thermoset support part, the high corrosion protection requirements of some customers can be met.In addition, a weight saving is achieved and the process time is significantly reduced by eliminating the time-consuming pretreatment process of the stainless steel support part.But there are challenges in using a thermoset support part.The design of a thermoset support part is discussed and the investigations are described.
