(pack)Piston-Rod guide K73 POLYESTER RESIN ID135mm-360mm(choose dimension)

Description

K 73 is a piston - rod guide ring designed to be used in heavy duty hydraulic and pneumatic systems.
PRODUCT ADVANTAGES
• High load bearing capacity
• Minimum static and dynamic friction coefficient for a minimum energy loss and operating temperature
• Able to be used behind the sealing element on dry condition
• High dimension stability during the operating temperatures
• Easy assembly
• Wide range of dimensions
APPLICATION
Mobile hydraulics , excavators , mining equipment , marine hydraulics , presses and heavy duty cylinders.

INSTALLATION
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 wiper must be oiled with system oil.
NOTES
To avoid hydrodynamic pressure k interval is given.
