UNP type

UNP type xipulin hole) seal and walka UNP groove are interchangeable and universal.

Main advantages:
● Large cross-section large pressure design
● Good water resistance and durability
Improvements have been made to prevent damage caused by back pressure.
● Improvements to prevent crawling
● Materials with good low temperature resistance
 

Scope of application:
Working pressure: ≤ 40Mpa
Working temperature: -30 ~ 100C
Surface speed: ≤ 0.5 m/s
Hardness: 92A 2
Mainly used for walking machinery outdoor machinery and other hydraulic cylinder on the piston seal.
Installation: This type of seal should have axial clearance, in order to avoid
To avoid damage to the sealing lip, do not pull the seal on the sharp edge during installation.
material: XA-2091 is a kind of nano-modified high-performance polyurethane material independently developed by xipuli, which has good high and low temperature resistance and hydrolysis aging resistance and small compression deformation.
