Category:

The Parker Prädifa PDF cylinder seals Profile G1 and G2 are elastomeric grooved rings that due to their symmetrical shape and their pointed sealing lips need a support ring. These support rings can either be made of Metal according to the in this brochure included drawing with dimension list or be made of rubber. The round cord is suitable as a rubber support ring and molded rings. Also, Plastic support rings are possible. The profiles G1 and G2 are square Cross-sections. In contrast to the profile G1, the profile G2 stronger sealing lips and therefore touches the Öttitm when depressurized

Extend even more intensely. These profiles are mainly called Cylinder seals used- It is too possible to seal piston rods to use. In this case, however, no plastic support ring is used will. As a special case, the Parker Praedifa profile G2 can also with connection sloping outwards be provided. Do this they usually do not have a support ring because of the Sealing edge below the total height, H, of the feeding ring.

Scope of application:

Operating pressure: 160 bar hydraulic
Operating – 30 to + 100 C hydr.
temperature: – 30 to + 80 C Pneum.
Sliding hydraulic <0.5 m / s
Speed: 1.0 m / s pneumatics.
Mainly for the devices in the hydraulics and tires here, however, only in connection with maintained compressed air.

Installation instructions:

The tolerance for the groove insertion should be h9, which gives the sealing lip sufficient prestress. If the value is placed on very little friction, the groove for the cylinder seal can be made with undersize, so that the pressure against the cylinder wall is reduced. However, this only applies to pneumatic devices. In contrast, the specified dimensions and tolerances in hydraulics must be observed.

Material:

The standard compound is a PDF elastomer based on NBR with a hardness of approx. 84 Shore A.
