HS Hydraulic stem seals

HS-RSD


Description:

The RSD seal, unlike the RSA type, has a special multifunction edge. Main advantages:

Reduces the sticking effect due to the fact that it holds the hydraulic oil between the secondary and dynamic edges.

Performs a wiper function.

Provides reliable shrinkage at low temperatures.

Performs function of stabilizer.


Technical specifications:

Pressure: < 400 bar at temperatures up to 60В°C.

Speed: < 0,5 m/s.

Temperature: from -35В°C to +100В°C with a peak value of +110В°C.

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


Material:

Name: polyurethane (PU).

Addition: wear resistant polyurethane, resistant to hydrolysis.

Properties: has a high modulus of elasticity, low residual deformation and high abrasion resistance.

Hardness: Shore 93 В± 2.

Material code: CРћ.


Installation:

To prevent damage to the seal before installation, it is necessary to observe the allowable surface roughness (grinding of the landing groove).

The seal must always be lubricated before installation, which in turn will facilitate the perfect seal operation.

For more information, see the Installation Instructions on page 1.2.14.
