Isoko ni ibikoresho bikomeye cyangwa bifatanye bihuza urunigi (roller) kugirango rwohereze icyerekezo. Uruziga rwubwoko bwa coget rukoreshwa muguhuza umurongo ufite ikibanza cyuzuye kumurongo uhuza cyangwa umugozi.

Imiterere y'amenyo ya spocket igomba kwemeza ko urunigi rwinjira kandi rusohoka neza neza kandi bizigama ingufu, bigabanya ingaruka no guhangayikishwa no guhuza iminyururu mugihe cyo gushakisha, kandi bigomba kuba byoroshye kubitunganya.

Ibipimo fatizo bya spock ni ikibanza, umurambararo wimbere, umubare w amenyo numurongo. Indangantego yumuzingi wa diameter, iryinyo yinyo yumuzingi diameter hamwe ninyo yumuzingi wumuzingi wa diameter ya spocket ni ibipimo nyamukuru byamasoko.
Isoko ifite diameter ntoya irashobora gukorwa mugice kimwe; amasoko afite diameter yo hagati bikozwe murubuga cyangwa amasahani asobekeranye; amasoko afite diametero nini bikozwe muburyo bwahujwe, akenshi hamwe nibikoresho byasimbuwe byerekanwa kuri hub.

Isoko ntoya ya diametre isanzwe ikorwa muburyo butagaragara, kandi hagati ya diameter yo hagati ikorwa muburyo bwa plaque ivugwa. Kugirango boroherezwe gukemura, gupakira no kugabanya ibiro, hakozwe umwobo mu isahani yavuzwe, kandi umurambararo munini wa diameter urashobora gukorwa muburyo bwahujwe. Impeta ninziga yibiziga birashobora gukorwa mubikoresho bitandukanye.

Ibikoresho by'isoko bigomba kwemeza ko amenyo y'ibikoresho afite imbaraga zihagije kandi akananirwa kwambara, bityo rero iryinyo ryinyo yisoko muri rusange ni ubushyuhe buvurwa kugirango bugere kubintu bikomeye.
