All profiles listed here are SKF standard machined K05 piston seals and can be produced in virtually any dimension and in different materials.
K05 piston seals are asymmetric, single-acting pneumatic lip seals designed to seal pressurized space against the atmosphere or – in case of back-to-back arrangement with intermediate guide ring – to seal between two pressurized spaces, mainly for reciprocating movements.
These seals are part of the comprehensive SKF machined seals assortment and the design is based on applications in standard pneumatic systems (lubricated or dry air with initial lifetime lubrication). 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 pistons in pneumatic cylinders
- Piston seal in heavy machine construction with impact loading
- Suitable for dry and lubricated air
- Can be used as pivot seal for small loads
Materials
Material selection has a significant impact on the seal performance as well as reliability of the whole system.
Recommended sealing materials and operating parameters are defined in the seal data sheets.
For K05-P S-ECOPUR is the recommended standard material.
For K05-R SKF Ecorubber-1 is the recommended standard material.
For increased wear resistance and higher pressure ranges we recommend the K05-P profile with 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 the K05-R profile made of SKF Ecorubber materials, but attention should be paid to the limitation in wear and pressure resistance.
For special requirements on service temperature and media compatibility up to a certain extent, various ECOPUR polyurethane materials are available.
Available seal versions
There are different versions of the K05 seals with specific features available (please find more detailed information in the related detailed profile descriptions and seal data sheets linked below).
