Härdade bussningar är särskilt lämpliga för applikationer med dynamiska belastningar som snabbt kan skada lager av stål eller brons. Dessa bussningar är tillverkade av material med en hårdhet på 58–62 HRC och kräver en härdad axel med en hårdhet på minst 62 HRC för att minimera slitage på axeln. Regelbunden smörjning är nödvändig för att säkerställa optimal prestanda.
Typ BGFR har invändigt cirkulärt diagonalt smörjspår, samt runt utvändiga omkretsen i mittsektorn. I det utvändiga smörjspåret finns ett genomgående smörjhål.
