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
