Design Choices for Retaining Ring Specifications

by:Tronshal     2022-03-02
For example, if you want to add a PTFE retaining ring to the O-ring groove of the static seal of the high-pressure oil cylinder, the size of the groove is designed in the design manual, but how to design or select the retaining ring?
In general, the height of the retaining ring should be consistent with the groove depth, and the thickness of the retaining ring should be 1~2mm, which can be determined by itself according to the extrusion situation.
The radius of curvature of the groove is 0.8~1.6 times of the wire diameter of the O ring, depending on the amount of compression, the fillet is less than 0.2.
