All profiles listed here are SKF standard machined S02 rod seals and can be produced in virtually any dimension and in different materials.
S02 rod seals are asymmetric, single-acting lip seals with integrated back-up rings designed to seal pressurized space against the atmosphere, mainly for reciprocating movements.
These seals are part of the comprehensive SKF machined seals assortment and the design is based on applications in standard hydraulic systems with conventional hydraulic oils. The operating parameters are as defined in the sealing and material data sheet. Requirements deviating from these parameters can be met to a certain degree by changing the geometry in the SKF SEAL JET machine software.
Application range
- Reciprocating rods in hydraulic cylinders, push rods, fittings
- Rod seal for applications with large extrusion gap and without specific impact loading
Materials
Material selection has a significant impact on the seal performance as well as reliability of the whole system.
For the S02-P and S02-PD designs ECOPUR/SKF Ecotal is the recommended standard material combination.
For the S02-R and S02-RD designs SKF Ecorubber-1/SKF Ecotal is the recommended standard material combination.
For special requirements on service temperature and media compatibility up to a certain extent, various ECOPUR polyurethane materials are available.
For increased wear resistance and higher pressure ranges we recommend S02-P made of ECOPUR polyurethane materials, but attention should be paid to the difference in chemical resistance and service temperature range.
For increased chemical and thermal resistance, we recommend S02-R made of SKF Ecorubber materials, but attention should be paid to the limitation in wear and pressure resistance.
The backup material is mainly selected based on the diameter (SKF Ecotal available up to 400 mm). Please consider moisture swelling when using SKF Ecomid.
Available seal versions
There are different versions of the S02 seals with specific features available (please find more detailed information in the related detailed profile descriptions and seal data sheets linked below).
