K73 POLYESTER GUIDE RING 50X55X5.6 PU

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.
