Mndandanda wa Roller Linear Motion Guide uli ndi chogudubuza ngati chinthu chogudubuza m'malo mwa mipira yachitsulo. Mndandandawu udapangidwa ndi mbali ya 45-degree yolumikizana. Elastic deformation of the linear contact surface, panthawi yotsitsa, imachepetsedwa kwambiri motero imapereka kukhwima kwakukulu ndi mphamvu zolemetsa kwambiri mumayendedwe onse a 4. Mndandanda wa RG linear kalozera umapereka magwiridwe antchito apamwamba pakupanga mwatsatanetsatane kwambiri ndipo utha kukhala ndi moyo wautali wautumiki kuposa mizere yanthawi zonse ya mpira.
