6. O-rings
SKF can supply O-rings in a wide range of sizes in accordance with various O-ring standards.

Inside diameter/cross section proportion
O-rings used in more demanding applications, such as those with higher operating pressures or larger misalignments, may require larger cross sections. SKF recommends inside diameter ID and cross section pro portions as provided in diagram 1.

7. Extrusion gaps and back-up rings

The size of the permissible extrusion gap depends mainly on the seal material, temperature and operating pressure. Harder materials provide a certain resistance to gap extrusion. When the permissible extrusion gap for the pressure and temperature in application is exceeded, back-up rings may be used to prevent the seal pressing into the gap and causing extrusion damage and possibly even premature failure. Figure 2 shows the O-ring behaviour at different operating pressures and conditions.
