Inxalenye yangaphakathi yesilayidi sesilayidi esingabonakaliyo kwiso lenyama yinkqubo yayo yokuthwala, ehambelana ngokuthe ngqo nomthamo wayo wokuthwala. Okwangoku, kukho izilayidi zebhola zentsimbi, izilayidi eziqengqelekayo kunye nezilayidi zamavili esilicon kwimarike. Owangaphambili ususa ngokuzenzekelayo uthuli kunye nokungcola kwi-slide rail ngokusebenzisa i-rolling yebhola yensimbi, ukwenzela ukuba kuqinisekiswe ukucoceka kwesilayidi sesilayidi, kwaye umsebenzi we-sliding awuyi kuchaphazeleka ngokungcola okungena ngaphakathi.
Ngelo xesha, ibhola yensimbi inokusasaza amandla ajikelezayo, iqinisekisa ukuzinza okuthe tye kunye nokuthe nkqo kwedrowa. I-debris eveliswa ngexesha lokusetyenziswa kwexesha elide kunye ne-friction ye-silicon wheel slide rail ikwimo yeeflakes zekhephu, kwaye inokunyuswa ngokuqengqeleka, kwaye ayiyi kuchaphazela i-sliding egudileyo yedrowa.
