Product introduction

METHOD OF OPERATION 

Product description

 When the application requirements make high 
demands on leakage control and reliability,  
a redundant sealing system is necessary to  
ensure reliable sealing of hydraulic cylinders  
at the piston rod. 

ADVANTAGES 

 -High static and dynamic sealing effect 
 -Low friction for reduced power loss 
 -High wear resistance for long service life 
 -Small groove 
 -Easy installation 
 -ISO 7425-2 grooves optional 
 -Available for any diameter from 8 to 2,200 mm 

APPLICATION EXAMPLES

 -Mobile hydraulics 
 -Standard cylinders 
 -Machine tools 
 -Injection molding machines 
 -Presses

Product Parameters

RIMSEAL is an elastomer energized seal element. The 
changes in seal position in the groove, necessary for optimum 
sealing function, are guaranteed by the combination of the two 
parts: the O-Ring and seal ring. 
In order to achieve a contact force increasing sealing effect 
with increasing pressure, the seal has a chamfer on the low 
pressure side which causes the seal to tilt slightly so that the 
seal ring is forced against the side of the groove. This creates 
an area of maximum pressure at the edge of the seal. 
When RIMSEAL  is used in a system with a double
acting scraper DA24 (DA22, DA17, DA27, Excluder®2 resp. 5 
or 500), the sealing function of the system must be assured 
even if pressure build-up occurs between Rimseal and the 
double-acting scraper. 
The high-pressure side of the seal ring also has a chamfer 
which, in the event of a build-up of pressure behind Rimseal, 
comes into contact with the flank of the groove. Rimseal 
moves in the groove so that a contact pressure distribution is 
obtained on the rod which enhances the back-pumping effect.
