Product Description

 

About U-cup Rod Shaft Seal

Single-lip U-cup profile made of polyurethane-MDI;suitable for medium to heavy duty  applications

Due to the special design, behind the dynamic seal lip,  its structure of slide segments interspersed by back-pumping channels features, excellent
back-pumping ability across the entire pressure range. The dynamic seal slide segments also have a micro-structure with excellent tribological and sealing characteristics. As well as increasing the sealing ability of the U-Cup , this also ensures a constant lubrication film underneath the seal sliding surface, reducing breakaway force even after prolonged periods of rest, and reduces dynamic friction force.

ADVANTAGES:
-Lower friction than standard U-Cups
-Lower heat generation
-High extrusion resistance
-Excellent dynamic and static sealing
-Optimum environment protection
-Back pumping ability over the entire pressure range achievedby grooved profile
-Suitable for sealing systems with double scraper
