Hydraulic and Pneumatic Seals...since 1975
DWR 506 is a piston - rod guide ring designed to be used in heavy dutyhydraulic systems.
PRODUCT ADVANTAGES
APPLICATION:
Mobile hydraulics , mining industry , excavators , hydraulic presses , heavy duty cylinders and pneumatic cylinders.
INSTALLATION:
DWR 506 is easily assembled into the housing by hand. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the guide ring must be oiled with system oil.
ATTENTION: The guidance must be placed where it is in direct contact with the media. DWR is not suitable for dry working conditions. Surface contact pressure value would decrease due to temperature rise.
MATERIAL: POLYESTER RESIN + PTFE
