Latest Patents

Stadler's latest patents include a radial shaft seal and a sealing arrangement. The radial shaft seal features a ring-shaped, metal supporting body and a sealing lip designed to separate a high-pressure hydraulic side from an atmospheric side. The sealing lip is pressed onto the shaft by an annular helical spring, ensuring effective sealing under pressure. In an uninstalled state, the working plane of the annular helical spring is positioned below that of the sealing edge, while in the installed state, both planes are approximately coplanar.

The sealing arrangement patent describes a rotary shaft lip seal positioned in a housing bore hole under radial prestressing. This design includes a sealing lip that surrounds the shaft to be sealed, mounted on a thrust ring made of tough material. The thrust ring's second leg is coated with elastomer, which maintains radial prestress against the housing bore wall. A roller bearing is strategically placed between the second leg and the shaft, enhancing the sealing effectiveness.
