O-Ring Groove Calculator

Rotary Seal

'Rod' styled O-ring grooves are commonly used dynamic rotary O-ring sealing configurations. This page specifically concerns dynamic (moving) rotary Rod O-ring seals.

The purpose of the calculator below is to serve as a groove calculator for Piston Seal O-ring grooves using all AS568+, JIS, common metric, and custom O-ring sizes. 

Please see our General Groove Guide for more information, or feel free to get in touch with our engineers if you have any questions. 

*Feet per minute = 0.26 X Shaft Diameter (inches) X rpm

**Total indicator reading between groove OD, shaft, and adjacent bearing surface

*** If clearance (extrusion gap) must be reduced for higher pressures, bearing length M must be no less than the minimum figures given. Clearances given are based on the use of 80 shore durometer minimum O-ring for 55.2 Bar (800 psi) max. See Figure 3-2 for recommended clearances when pressures exceed 55.2 Bar (800 psi).

**** The use of O-rings as high speed rotary shaft seals is usually not recommended for applications requiring lower than -40°C (-40°F) or higher than 121°C (250°F) operating temperatures.

***** The O-ring gland in a rotary shaft application should not be used as a bearing surface. The shaft should be contained by bearings that will permit the O-ring to operate under the lowest possible heat and load

+ Please note that some AS568-0XX  O-rings have atypical cross sections. Please see our General Groove Guide for more information, or feel free to get in touch with our engineers if you have any questions about O-rings, gaskets, & custom molded parts.
