Track roller screws yog cov khoom tseem ceeb hauv cov cuab yeej siv tshuab.
Lawv feem ntau yog siv los txuas cov menyuam taug qab thiab lub cev tseem ceeb ntawm cov khoom siv, thiab ua haujlwm tseem ceeb ntawm kev txhawb nqa qhov hnyav ntawm cov khoom siv. Taug qab cov menyuam screws muaj lub zog siab thiab ruaj khov thiab muaj peev xwm tswj tau qhov kev sib txuas ruaj khov hauv qhov chaw ua haujlwm hnyav. Tom qab cov txheej txheem kev kho cua sov tshwj xeeb, qhov hardness thiab hnav tsis kam yog txhim kho. Qhov ntau thiab tsawg thiab qhov tshwj xeeb ntawm cov menyuam cov ntsia hlau sib txawv raws li cov khoom siv sib txawv thiab cov khoom siv thauj khoom. Thaum lub sijhawm ua haujlwm ntawm cov khoom siv, cov menyuam cov ntsia hlau yuav tsum tau kuaj xyuas thiab tswj xyuas tsis tu ncua kom ntseeg tau tias lawv nruj thiab kev ntseeg tau, kom ntseeg tau tias kev ua haujlwm ib txwm muaj thiab kev pab cuam lub neej ntawm cov khoom siv.
