Wiper Seals


WIPER SEALS

Rod wipers for alternative linear movements have been designed to give first-class protection to seals and driving bodies in hydraulic and pneumatic cylinder applications. 

The main function of the rod wiper is to keep the rod clean from any possible impurity.

The •FP• rod wipers have a chamfer on the outside diameter to facilitate the press fitting into the housing. To simplify the installation, the bore should have a chamfer as per DIN 3760.

Applications

General condition of use

For the correct use of rod wipers we suggest the following mounting instruction.

Piston
The shaft surface should have a roughness of Rmax <= 2 μm.

Housing
The housing of the wiper has to be machined to ISO H8 norm, and completed with chamfers.
