All profiles listed here are SKF standard machined K16 piston seals and can be produced in virtually any dimension and in different materials.
K16 piston seals are single-acting axially clamped lip seals (also referred to as “hat seal or cup leather”), designed to seal pressurized space against the atmosphere or – in case of back-to-back arrangement – to seal between two pressurized spaces.
These seals are mainly used for reciprocating movements, but also for minor rotating and pivoting 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 use in pneumatic systems is quite common as well. 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 and pneumatic cylinders, push rods and fittings
- Piston seal for applications with small extrusion gap and without special impact loading
- Replacement for old leather seals
- Can also be used in rotating and pivoting applications (reduced pressure)
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 sheet. ECOPUR is the recommended standard material for these seals.
For special requirements on service temperature and media compatibility up to a certain extent, various ECOPUR polyurethane materials are available.
For increased chemical and thermal resistance, we recommend SKF Ecorubber materials, but attention should be paid to limitations in wear and pressure resistance.
Available seal versions
There are two versions of the K16 seals with specific features available (please find more detailed information in the related detailed profile descriptions and seal data sheets linked below).
