Description


Description:

The RPS seal combines two different types (rod and piston) at the same time. Due to two symmetrical edges, the cuff is used to seal both the stem and the piston in single-acting and double-acting cylinders. 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).

Description:

The PSA cuff is a piston seal and is used for single-acting and double-acting cylinders. This type has asymmetric edges, which guarantees constant contact with the inner surface of the cylinder, even with a large displacement.

The installation is made in a semi-open groove by means of an overlap, since the material has a high modulus of elasticity.

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 oil and fuel (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:

It is necessary to observe the permissible value of surface roughness (grinding of the landing groove). Mount the cuff for the lip of the landing groove until the piston moves lightly. The seal must always be lubricated before installation.

Description:

The PAE seal is specially designed for use under extreme conditions. When it is not possible to reduce the clearance between the cylinder and the piston, the pressure is very high (more than 250 bar), the PAE cuff with an elastic anti-extrusion ring becomes the most optimal option.


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).

Properties: PU - has a high modulus of elasticity. The anti-erosion ring is made of polyacetal material (POM) with a high tensile strength.

Hardness: Shore 93.

Material code: CO.


Installation:

The cuff is mounted in a semi-open mounting groove. Anti-extrusion ring is installed after fixing the seal itself.

To prevent damage to the cuff during application, it is necessary to observe the permissible surface roughness before the installation (grinding of the landing groove).

Description


Description:

The KDSP cuff is specially designed as a piston seal with interchangeable mounting rings to ISO 6547.

This type consists of three elements: seals made of polyurethane in the middle and two wiper rings made of polyacetal at the edges.

Due to the high modulus of elasticity and hardness of the central sealing cuff (higher than NBR material), there is no need for anti-extrusion rings.

The special geometric shape of the cuff reduces friction (at the first start of the equipment and under operating conditions).


Technical specifications:

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

Speed: < 0,8 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:

central ring - material polyurethane Shore 93 A, Material code: CO;

wiper 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.

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

Description:

The KDAE seal set includes a polyurethane cuff in the center and two anti-extrusion rings on the sides. The design of a high-elasticity polyurethane element and two high-strength elastomer rings ensures a stable seal position even when used under extreme conditions. Thanks to the use of polyurethane material (compared to NBR), friction is reduced, prolonging the life of the cuff.

The special geometric shape of the KDAE also significantly reduces friction (when the equipment is first started and under operating conditions), and the cuff efficiency in operation is much higher than that of NBR seals.


Technical specifications:

Pressure: from 0 to 400 bar.

Speed: < 0,8 m/s.

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

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


Material:

This cuff is made of the following materials:

central ring - material polyurethane Shore 93 A, Material code: CO;

support rings - elastomer TPE Shore 63 D (L2);

Material code: CR.


Installation:

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

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

It is recommended to use grease for a more convenient cuff installation.

Description


Description:

The PSP piston seal is specially designed for single-acting and double-acting pneumatic cylinders.

A deep seat between the dynamic and static edges, including their continuous radius, increases the cuff slip even with a lack of lubrication.

The reduced dimensions of the seal, together with the high flexibility of the material, also facilitate easier installation in a closed fitment groove.


Technical specifications:

Pressure: < 20 bar.

Speed: < 1 m/s.

Temperature: -30В°C to +90В°C.

Operating environment: air with and without lubricant, mineral oils and grease (see Table 1 on page 1.2.4).


Material:

Standard material: polyurethane 90 Shore A.

Standard material code: B0.

Alternative material: 85 Shore Рђ.

Alternative material code: A0.


Installation:

It is recommended that a certain surface roughness value is observed (grind the landing groove) to avoid damage to the cuff.

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

The rod must be ground and chamfered (see page 1.8.6).
