  • Description

    Description The profile OK piston sealing set is primarily designed for heavy-duty hydraulic applications and is preferably used in double-acting cylinders. It is extremely robust and withstands even extreme pressure peaks.The sealing set consists of a plastic slide ring and an elastomer energizer. * Extreme wear resistance.* Easy installation on single-part piston without assembly aids due to the split design of the sealing ring.* Assembly on one-part piston is possible.* Insensitive to extreme pressure peaks.* Extremely high extrusion resistance.* High extrusion resistance in case of high pressures and large gaps due to the special compound properties of the seal ring.* Dimensions according to ISO ­7425-1.* Short axial assembly length.* Installation in closed and undercut housings.* Further dimensions of machined series with short lead times available. Application Heavy-duty hydraulic applications. Materials Polyamide (PA)

MATERIALS

PA

There are different types of polyamides, more commonly known as “nylons”. The most important are: PA 6, PA 66, PA 11 and PA 12. These types of nylons have different physical properties, mainly their composition and the structure of their molecular chains. The PA6G polyamide is characterised by its stiffness, strong sliding abilities, excellent machinability and excellent resistance to wear and abrasion.
