U型圈RU6-ZURCON U-CUP RU6
Description
Additional to the machined seals Stepseal 2K and Rimseal
for housings due to ISO 7425/2 (rubber energised plastic
seals) the U-Cup type RU6 has been developped as an
injection molded seal of polyurethane material to fit in the
same ISO housings. The integrated NBR O—Ring (only
available for series RU62 - RU64) improves the
performance at low pressure and low temperature
applications. Polyurethan (Zurcon Z20) is a proved
material for U-cups due to their good mechanical
properties.
Application Examples
- General hydraulic cylinders
- Injection molding machines
- Lift trucks
- Agricultural machines
