China Ru0 T20 B3 Type hydraulic Cylinder Rod Seal Polyurethane Seal

Description
The B3 profile is a U-ring type single acting rod seal with asymmetrical polyurethane lips. It can be assembled in a groove according to standard ISO 5597. The diameter of the B3 profile is designed to ensure a tight static side seal when installed. The knife trimmed, beveled lip does an excellent job wiping fluid film.
Design Standard
This series of products conform to Trelleborg company RU0 series and Parker's B3/BS series standards.

Materials
PU
Polyurethane is a material that has the elastic properties of rubber. The proportion in its composition (diisocyanate, polyol, chain extender) is determined by its properties. This material is characterized by a strong mechanical resistance, good wear resistance, high elastic modulus, good flexibility and a very good ozone and oxidation resistance.
