K46

K46 is a four piece doble acting compact seal consisting of  polyurethane sealing ring with NBR energizer O-ring and two special profile guide rings made of thermoplastic to absorb transverse forces.

PRODUCT ADVANTAGES
•Superior sealing performance
•No requirement for an additional guide ring due to the compact design
•Economic sealing and guiding solution
•Simple groove design , one-piece piston possible
•Reducing piston machining cost due to low cross-section thickness
•Easy installation

APPLICATION
Agricultural machinery , industrial applications

INSTALLATION
Easily assembled into one-piece piston because the back-up rings and guide rings are been produced in split forms. 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.
