Rod Seals KVK-UN O Rings Hydraulic Seals 

Overview UN type seals are one-way acting sealing elements, in hydraulic cylinders, mainly used for piston rod sealing, in many applications, especially in mobile machinery, automobiles, forestry and mining machinery, under harsh working conditions , has good mechanical properties. In heavy-duty occasions, it has a very good effect when used in conjunction with the RS-type step seal. advantage In addition to the advantages mentioned above, as well as the advantages of good sealing effect and easy installation, the sealing element also has the advantage of low friction in the low pressure range. Scope of application It is suitable for piston rod sealing and has a wide range of applications, especially in hydraulic equipment such as mobile machinery, automobiles, forestry and mining machinery. Technical parameter Pressure: ≤32 Mpa, when the pressure is higher than 20MPa, it is recommended to use a retaining ring. Temperature: -30℃ ~ +80℃ Speed: Reciprocating ≤0.8m/s Med…
