a) Fur yar: samaynta isku dhafan;
b) Furayaasha waaweyn iyo kuwa dhexdhexaadka ah: kala-baxa ka dib sameynta - inta badan la isticmaalo, shuruudaha heerka inta badan waxaa loogu talagalay;
c) Fure weyn: iyadoo ay ugu wacan tahay shuruudaha gaadiidka iyo furitaanka iyo arrimo kale, xirmada ugu horreeya ee sameysma, ka dib alxanka wadajirka ah.
Kahortag kala goynta xagasha r-dhamaadka saxanka si aad u ilaaliso dhumucdeeda iyo walbahaarkeeda sare.
Kaliya jihooyinka alxanka ee radial iyo wareegsan ayaa loo ogol yahay tolida. Mustaqbalka, furayaasha waaweyni waxay ka dhigi karaan shuruudan mid duugowday. Masaafada kala-goynta waa in ay ahaataa ugu yaraan 100mm oo aan ka yarayn saddex jeer qaddarkaas. (Qaabka kiimikaad ee ku jira aagga kulaylka alxanka saameeya, kaas oo ah aagga walaaca sare, waa la gubi doonaa. Markaa ka fogow aagga culus ee kacsanaanta weyn. Si kastaba ha ahaatee, qalabka qaboojiyaha ayaa leh sifooyin u gaar ah oo adkeynaya in la gaaro baahidan.
Erayada "plug" iyo "head plug" waa la isweydaarsan karaa. Qalab farsamaysan oo leh shaqada xidhiddu waa fur. loo isticmaalo warbaahinta sida biyaha, saliidda, uumiga, iyo kuwa kale. Plugs waxay leeyihiin furaha birta, madaxa fur, iyo fur cunaha ah.
Nidaamka mitirka, nidaamka Ingiriiska, iyo nidaamka Ameerika waa qaybinta ay sameeyeen dunta kala duwan.
Hex plugs, hex plugs, xargaha dunta koorta, furayaasha labajibbaaran, iyo furayaasha laga sameeyay walxo kala duwan sida caag, qaboojiyaha ciyaaraha qabow, 45# furayaasha, birta aan birta lahayn, iyo naxaasta ayaa dhamaantood loo kala saaray qaabka ay u samaysan yihiin dhibcaha kala duwan.
