Rod U-Ring R01

DESCRIPTION
U-Ring R01 is a U-seal with an asymmetric profile and shortened inner lip. The recommended working pressure is up to 10 MPa. If the protective ring is installed, the working pressure will increase to 16 MPa. It has very good static and dynamic tightness and it is a good choice for specific requirements, wide operating temperature range and easy installation.

APPLICATION
Light hydraulic cylinders.
Pneumatic cilinders
Earth moving equipment
Industrial vehicles
Agriculture equipment
