Härdad bussning med smörjspår
Härdade glidlager används främst där de dynamiska belastningarna slår sönder och för snabbt sliter ner annat glidlager av stål eller brons. Dessa lager skall smörjas. Hårdheten på materialet är 58-62 HRC och kräver härdad axelhårdhet på minst 62 HRC för att undvika slitage på axeln.
Typ BGFR har invändigt cirkulärt diagonalt smörjspår, samt runt utvändiga omkretsen i mittsektorn. I det utvändiga smörjspåret finns ett genomgående smörjhål.
