K52 is a single acting pneumatic wiper ensuring that foreignparticles are not introduced into the hydraulic cylinders. The lip isdesigned in a particular way that it functions as a rod seal andwiper.

PRODUCT ADVANTAGES
• Superior sealing effect
• Superior wiping effect
• Low static and dynamic friction
• Minimal space requirement
• High wear resistance

APPLICATION
Compact and special small cylinders.

SURFACE ROUGHNESS Rmax
Sliding Surface  Ød ≤4 μm
Groove Base  ØD ≤10 μm
Groove Flanks  B ≤15 μm

INSTALLATION
It can be assembled into closed groove by hand. K52 does not need additional element such as circlip for axial fitting within the housing. We recommend using special assembly tool. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil.

NOTES
For special applications that require high temperatures , K52 can be produced in FKM material.
