Product Description

Product Description

Description

 WG is a very effective and reliable low friction seal. It is particularly suitable as a piston seal in both high and low pressure systems.The double-acting WG Ring  is a combination of a Caimi based slipper seal and an energizing O-Ring. It has an interference fit which together with the squeeze of the O-Ring ensures a good sealing effect even at low pressure. At higher system pressures, the O-Ring is energised by the fluid, pushing the Ring against the sealing face with increased force.
  The geometry of the Ring ensures good static sealing and allows the lubricating hydrodynamic fluid film to be built under the seal in linear applications.
 
 
 ADVANTAGES
 -No stick-slip effect when starting for smooth operation
 - Minimum static and dynamic friction for a minimum energy 
loss and operating temperature
 - Suitable for non lubricating fluids depending on seal material 
for optimum design flexibility
 -High wear resistance ensures long service life
 - Installation grooves acc. to ISO 7425-1 as well as 
Step seal standard groove dimensions
 - No adhesive effect to the mating surface during long period 
of inactivity or storage
 - Suitable for most hydraulic fluids in relation with most 
modern hardware materials and surface finish depending on 
material selected.
 -Suitable for environmentally friendly hydraulic fluids
 -Available for all cylinder diameters up to 2,700 mm.
 
 
APPLICATION EXAMPLES
-Injection molding machines
 -Machine tools
 -Presses
