Overview

Symmetric Seal-UHS series

Product Details

Description

The UPH profile is a U-ring type single acting seal with symmetrical polyurethane lips. It can be used for both rod and piston applications.

Technical data

Temperature	-30°C/+110°C
Pressure	30 MPa
Speed	0.5 m/s
Medias	Mineral hydraulic oils

Applications

Light and medium load hydraulic reciprocated sealing system. Widely used at industries such as machinery, light machinery, agricultural machinery, injection molding machinery, forklifts, cranes, autos, forestry machinery and mining machinery, etc. Favorable mechanical characteristics even under tough working conditions.

Materials

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.

Chemical resistance	Pure aliphatic hydrocarbons (propane, butane) Mineral oils and greases Silicone oils and greases Water up to +50°C
Compatibility issue	Ketones, esters, ethers, alcohols and glycols Hot water, steam, alkalis, amines and acids

Advantages

Optimized sealing effect
Excellent abrasion resistance
Very good wear resistance

high wear resistance, low pressure deformation and excellent anti-extrusion performance

tear resistance especially in bending and tensile

easy installation

no effects to heavy load and rod bending

low friction in low pressure range compare to double seal lip
