HDSO is a single acting scrapper ensuring that foreign particles are not introduced into the hydraulic cylinders , avoiding wear and damage to all the internal components including seals.
Especially used in heavy construction machinery that operate in the open field , telescopic cylinders , cranes , mining equipment and loading platforms.
Open housing is recommended but closed grooves can be used for wipers bigger than 40 mm inner diameter. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the wiper must be oiled with system oil.
HDSO wipers are single action and can be used with combination of all rod sealing elements
