Hauv cov khoom siv sib khi zoo, kev sib txhuam thiab hnav yog qhov tseem ceeb cuam tshuam rau O-ntiv nplhaib puas. Qhov℃ntawm hnav feem ntau yog nyob ntawm qhov loj ntawm kev sib txhuam quab yuam. Thaum cov kua siab tsawg, qhov loj ntawm O-ring frictional quab yuam nyob ntawm nws pre- compression. Raws li cov kua dej ua haujlwm yog pressurized, lub zog sib txhuam nce nrog kev ua haujlwm siab. Hauv qab 20 MPa, qhov kev sib raug zoo no yog kwv yees li linear. Tshaj li 20 MPa, qhov nce ntawm qhov chaw sib txuas ntawm O-nplhaib thiab cov hlau nto maj mam qeeb nrog kev nce siab, thiab qhov nce ntawm kev sib txhuam quab yuam kuj qeeb raws li.
Raws li ib txwm muaj, lub neej kev pab cuam ntawm O-nplhaib yuav txo tau kwv yees li quadratically nrog cov kua siab. Kev sib txhuam ntau zog ua rau muaj kev sib txhuam tseem ceeb ntawm lub rotating lossis reciprocating ncej thiab O- nplhaib. Txij li feem ntau O-rings yog ua los ntawm roj hmab, uas muaj cov thermal conductivity tsis zoo, qhov kev sib txhuam ntawm cov cua sov ua rau cov roj hmab laus, ua rau O-ring tsis ua hauj lwm thiab cuam tshuam nws txoj kev sib khi. Kev sib txhuam kuj ua rau muaj kev puas tsuaj rau lub nplhaib O-, txo nws cov compression.
Kev sib txhuam hnyav tuaj yeem ua rau lub ntsej muag puas tsuaj sai sai rau O- nplhaib, ua rau poob ntawm nws cov khoom sib khi. Thaum siv rau pneumatic reciprocating seals, kev sib txhuam kub tuaj yeem ua rau adhesion, ntxiv kev sib txhuam. Txawm tias nyob rau hauv qis speeds, kev sib txhuam tsis kam nyob rau hauv kev txav cov ntsaws ruaj ruaj tuaj yeem ua rau nkag mus, cuam tshuam rau kev ua haujlwm ntawm cov khoom thiab cov tshuab. Yog li ntawd, kev sib txhuam kev ua tau zoo yog qhov tseem ceeb rau kev txav cov ntsaws ruaj ruaj.
Lub coefficient ntawm kev sib txhuam yog qhov ntsuas ntsuas ntawm kev sib txhuam cov yam ntxwv. Synthetic roj hmab muaj qhov coefficient ntawm kev sib txhuam. Txij li thaum cov ntsaws ruaj ruaj nyob rau hauv cov lus tsa suab yog feem ntau nyob rau hauv ib tug sib tov lubrication lub xeev uas ua hauj lwm cov roj los yog lubricant, cov coefficient ntawm kev sib txhuam feem ntau yog qis dua 0.1. Qhov loj ntawm kev sib txhuam feem ntau nyob ntawm qhov hardness ntawm qhov chaw thiab qhov roughness ntawm cov khoom kaw.
