HP Hydraulic piston seals

HP-KDSA


Description:

The KDSA seal includes a central sealing lip made of NBR material, two anti-extrusion rings and two outer guide rings that secure the piston in a straight line in the cylinder.


Technical specifications:

Pressure: from 0 to 300 bar with a peak value of up to 400 bar at a temperature of +60В°C.

Speed: < 0,5 m/s.

Temperature: -30В°C to +100В°C.

Operating environment: mineral oil (see Table 1 on page 1.2.4).


Material:

This cuff is made of the following materials:

center ring material NBR Shore 70 A В±3;

anti-extrusion rings - thermoplastic elastomer (TPE);

outer guide rings - polyacetal (POM).

Material code: CX.


Installation:

The seal can be installed in a closed groove in an integral piston, or in an open groove in a piston consisting of two parts.

Sealing components are installed in the following order:

1. Center ring made of NBR material;

2. Anti-extrusion rings;

3. Guide rings.

The permissible roughness of the piston surface must be observed during the installation of the seal to avoid damage to the rubber ring.
