Description


Description:

Seal type TSS consists of two rings. A ring made of PTFE material filled with bronze is a dynamic part, and an o-ring playing the role of an activator is the static part.


Technical specifications:

Pressure: < 600 bar.

Speed: < 15 m/s.

Temperature: from -30В°C to +100В°C - for the standard type of o-ring made of NBR material, with short-term peak values up to +120В°C. For a different temperature range, an o-ring of appropriate (excellent) material.


Material:

Name: PTFE, filled with bronze, for a standard type, and an o-ring made of NBR (nitrile butadiene rubber).

Material code: TN.


Installation:

Seals made of PTFE material require special precautions when installing in comparison with other types. It is necessary to observe the permissible value of surface roughness (grinding of the landing groove). It is recommended to perform the installation in the following sequence:

place the o-ring in the seat;

insert a ring from PTFE using special tools.

(see Figure 9, page 1.2.15).

Description:

The RSO rod seal is designed to replace PTFE seals or joint applications with them, since the dimensions of the seats are exactly the same. Inside the circular groove an o-ring is installed, which activates the static and dynamic edges even at zero pressure.

Due to the low coefficient of friction, this type of seal works excellently at low speeds and pressures.

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: CN.


Installation:

It is necessary to observe the permissible value of the surface roughness (grinding of the landing groove, for all its dimensions). For more information, see the Installation Instructions on page 1.2.14.

Description


Description:

The RBR ring is a protective ring and is designed specifically for use as a the main seal together with seals with asymmetric edges (see RSA on page 1.3.1). The main function of this type is to maintain the working pressure of the auxiliary seal. RBR is not It has a full sealing effect, therefore, between the two seals, an oil cavity. Thanks to the special profile of the RBR ring, the growing pressure will come out into the space cylinder when certain values ​​are reached. The seal acts as a valve and also is designed to compensate peak pressure values.


Technical specifications:

Pressure: < 400 bar at +60В°C.

Speed: < 0,8 m/s.

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

Operating environment: 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. For the anti-extrusion ring, it is proposed to use polyacetal material (POM) with a high tensile strength.

Material code: CR.


Installation:

Installation is made in a closed landing groove. It is necessary to first place the seal of polyurethane, and then - to mount the anti-extrusion ring.

A profile with identical edges and a deep groove provides low friction and linear motion even at low pressure.


Technical specifications:

Pressure: < 400 bar at +60В°C.

Speed: < 0,5 m/s.

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

Operating environment: mineral 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: CO.


Installation:

High elasticity modulus of polyurethane facilitates installation.

It is necessary to observe the permissible value of the surface roughness (grinding of the landing groove, for all its dimensions).
