Product Description

U-Cup  Rod Seal
 

U-Cup Rod Seal are used as single-acting, single-lip, compact seals. This seal can be installed in a simple way and positioned by an interference fit on the outer diameter of the seal, creating a static seal. It has an asymmetric sealing lip with a shorter inner lip. 

It possess a powerful dynamic lip ,it's static lip have a wide contact area , which brings a valid positioning in the groove.

OPERATING CONDITIONS

Pressure: 40 MPa

Speed: 0.5m/s or 0.7 m/s

Temperature: -50 °C to ~ 110 °C

Media : mineral oil ,hydraulic fluids(besides HFC-water glycol,HFD- Phosphate ester synthetic liquid ,Brake Fluid),fuel oil and water

Product Advantages:

 

- Simple groove design

- Excellent wear resistance   

- Insensitive to shock loads and pressure peaks

- Low permanent compression set

- High resistance to extrusion

- Applicable to harsh working conditions

- Long service life

- Easy to install

-Betted  Performance than  Moulded Seals.
