Igrisi inokusebenza okuphezulu kokuthanjiswa ngaphandle kokuwohloka komsebenzi we-Ball Screw. Ngokubanzi, kuyaziwa ukuba uphawu lokusebenza lweZikrufu zeBhola luphenjelelwa ziipropathi zeGrisi. Ngokukodwa, ukuxhathisa kweGrisi kuphembelela iBhola Screw Torque emva kokufaka iGrisi. Ukukhethwa kweGrisi kubaluleke kakhulu kwiMiniature Ball Screws. I-KGG iphuhlise i-Ball Screw grisi egqwesileyo, enokusebenza okuphezulu kokuthanjiswa ngaphandle kokuwohloka kokusebenza kweBhola Screw. I-KGG ikwaphuhlise iGrisi yayo eyodwa, egcina imvakalelo egudileyo kunye nongcoliseko oluncinci phantsi kwemeko yegumbi ecocekileyo. Sicinga ukuba eyona Grease ekhethekileyo ilungiselelwe ngokulandelelanayo ngokusetyenziswa komthengi.
