There are two main types of back-up rings: symmetric and asymmetric. Symmetric back-up rings are identical in shape and can be used on either side of the seal. Asymmetric back-up rings have a unique shape that is designed to provide additional support to the seal on one side only. Asymmetric back-up rings are typically used in applications where there is a high risk of extrusion, such as in high-pressure hydraulic systems.
In addition to preventing extrusion, back-up rings can also be used to reduce friction between the seal and cylinder wall. The back-up ring acts as a guide for the seal, ensuring that it moves smoothly and evenly along the cylinder wall. This reduces wear and tear on both the seal and cylinder wall, extending the life of both components.
Overall, back-up rings are an essential component in hydraulic and pneumatic systems. They provide critical support to seals, preventing extrusion and reducing friction. By using high-quality back-up rings, system designers can ensure that their systems operate reliably and efficiently over an extended period of time.
