UNR type

UNR type xipuli "piston rod seal and walka UNR type groove size are interchangeable and universal.

Main advantages
● Large cross-section design, can be used for large pressure range.
● Good water resistance and durability.
● Improvements have been made to prevent damage caused by back pressure.
Improvements have been made to prevent crawling.
● Materials with excellent low temperature resistance are used.
● can also be used for special low temperature hydraulic oil.
 

Scope of application
Working pressure: ≤ 40Mpa
Working temperature: -30~100 ℃
Surface speed: ≤ 0.8 m/s
Hardness: 92A ± 2
Mainly used for walking machinery, outdoor machinery and agricultural machinery industry hydraulic cylinder piston rod and plunger seal.
Installation: This type of seal should have an axial clearance. Avoid damage to the sealing lip and do not install the seal on a sharp edge. Pull up.
Material: XA-2092 is a kind of nano modified high performance polyurethane sealing material independently developed by xipuli °, which has excellent high temperature resistance and hydrolysis stability and small compression deformation.
