K06 customized machined piston seals

All profiles listed here are SKF standard machined K06 piston seals and can be produced in virtually any dimension and in different materials.

K06 piston seals are hydraulic 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 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 pistons in hydraulic cylinders 
• Piston seal for applications with small extrusion gap and without special external loading 
• Can also be used as pivot seal at low loads 
• Repair seal for older equipment 
• Replacement for rubber fabric seals of older equipment

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 special requirements on service temperature and media compatibility, various ECOPUR polyurethane and SKF Ecorubber materials are available. 

For increased wear resistance and higher pressure ranges we recommend K06-P 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 K06-R made of SKF Ecorubber materials, but attention should be paid to the limitation in wear and pressure resistance.

Available seal versions 

There are different versions of the K06 seals with specific features available (please find more detailed information in the related detailed profile descriptions and seal data sheets linked below).
