O Ring Clamping Force Calculation

Sometimes an approximate method is good enough.

O ring clamping force calculation. By simply entering installation specifications for an application it recommends o ring sizes housing layout and corresponding part numbers. Figure 5 primary wall contact stress profile for unrestrained unlubricated axially loaded o ring the only fixed case stress parameters results vernacular for this discussion includes primary wall and lateral wall the primary wall or walls are the surfaces which move together to force the compression of the o ring. This fastener bolt torque calculator will estimate the unknown torque diameter axial force applied and coefficient of turning friction for the given conditions. Info o ring compression.

The force generated by the o ring compression can be calculated there is some data for this in the handbook link below but it s easier to just make up a rig and test it using the o ring compound of your choice. The o ring calculator tool is intended to form the basis of an o ring installation and assist with selection of o ring and hardware dimensions. Calculate results reset calculator generate printable document results. You need to be registered and logged in to see the o ring calculation software.

O ring compression force. See the below compression force table along with the compression load tables in the links below. Gap mm sealing gap mm with an eriks account you can save open or delete your designs. Both are interlinked thus ensuring the best possible combination of the calculated o ring size and material choice.

See table below for how much clamping force is available from manual clamp straps of various sizes with a 2 to 1 clamping force ratio to compare with power clamp forces. O ring compression groove depth incl. O ring compression force is the force required to compress an o ring the amount necessary to maintain an adequate sealing line of contact. Clamping force calculations can be quite complicated.

See torque force design equations webpage and torque chart page for recommended fastener torque and equation data. The o ring selector covers both imperial and metric standards.
