HS Hydraulic stem seals

HS-RSB


Description:

The RSB seal, in contrast to the RSA type, has a special multi-functional edge. Main advantages:

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

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: -35В°C to +100В°C with peak value +110В°C.

Operating environment: mineral and hydraulic oil.


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: CO.


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 facilitates installation and ensures perfect sealing performance.

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