1. Kuskuren "Mafita ta Duniya" : Wasu sun yi imanin cewa mahaɗan duniyoyi na tsaye za su iya maye gurbin maƙallan kwance gaba ɗaya. A zahiri, lokacin da ɗanko na abu ya wuce wani muhimmin ƙima (ya danganta da ƙayyadaddun kayan aiki), girman girgizar shaft ɗin cantilever na tsaye zai wuce iyakokin aminci. Tilasta aiki na iya haifar da lalacewar bearing ko ma haɗarin karyewar shaft.
2. Yin sakaci da Tasirin Faɗaɗawar Zafi : Masu ƙulla maƙallan kwance suna buƙatar tsari mai kyau na tsatsauran rabe-raben tsakanin sandunan biyu (yawanci a matakin milimita). A yanayin zafi mai yawa, idan ba a yi la'akari da bambancin da ke tsakanin sandunan da kwano ba, zai iya haifar da ɓacewar sharewar (haifar da kamawa) ko kuma ya yi girma sosai (haifar da gazawar yankewa). Wannan babban matsala ce a ƙira da ƙera injunan kwance.
3. Rashin Ingantaccen Tsaftacewa : Ga kayan lantarki masu inganci ko na magunguna, dole ne a tabbatar da fa'idar da ke tattare da injunan tsaye ba tare da wani yanki ba ta hanyar amfani da tsarin Clean-In-Place (CIP).
