Product Description

About  Dumbbell  Type  Radial Seal 
 

In current hydraulic cylinder seal system design, O-Ring or O-Ring/Backup Ring combinations are mainly used as static seals. However, this sealing solution hides the risk that during assembly the O-Ring may become twisted and that the position of the Back-up Ring is not optimal. This solution also exhibits weaknesses with regard to pressure pulsation and the ingress of dirt. 

This seal as a single component static hydraulic seal offers a good alternative in such cases.It  allows general use in hydraulic cylinders,such as : Fork lifts, Mobile hydraulics, Industrial hydraulics, Machine tools, Injection molding machines, Hydraulic presses, Cartridge valves.

 

Advantages:


               -High resistance to twisting

               -Easy assembly

               -Long service life

               -High extrusion resistance
