O-rings are one of the most common sealing solutions. SKF supplies O-rings in a wide range of sizes and different materials, which make them appropriate for a wide variety of operating conditions and applications. They are easy to install and they enable a simple and cost-effective seal housing design.
O-rings maintain sealing contact force by radial or axial deformation in the seal housing between two machine components. The most important criteria that influence the maximum operating pressure at which O-rings in static radial sealing can be used are the following:
·Extrusion gap
·Material (→ Materials)
·Sealed fluid
·Temperature
Under specific conditions, there is a risk for gap extrusion (→ Extrusion gaps and back-up rings).
