WitrynaO-rings with smaller cross sections are squeezed by a higher percentage to overcome the relatively higher groove dimension tolerances. In static applications the recommended squeeze is usually between 15-30%. In some cases the very small cross sections can even be squeezed up to 30%. In vacuum applications the squeeze can even be higher. WitrynaFirst find the chart for the O-ring cross section size: 0.070”, 0.103”, 0.139”, 0.210” and 0.275”. Next, locate the O-ring compression or squeeze on the x-axis of the chart. …

WitrynaFriction and Wear . O-ring load a sealing surface due to their own resilience compounded with any system pressure. When the surface to be sealed moves relative to the O-ring, frictional forces are set up producing two effects: one leads to wear and the other reduces the useful load which a cylinder can transmit..

"WitrynaThe O-ring's O.D. should not exceed 3% of the rod gland diameter for O-rings with an I.D. greater than 250 mm, or 5% for O-rings with an I.D. smaller than 250 mm. For O-rings with an I.D. smaller than 20 mm, this is not always possible due to tolerance issues, which can result in a greater O-ring O.D. interference. " - O ring friction calculation
