It is very likely that this unit was named after a former commander, one Sabinus, whose exact identity, however, remains unknown. The only epigraphic evidence of this unit in Britain is a tombstone at Halton Chesters on Hadrian's Wall, which has been dated to the first half of the third century; they were stationed there for the remainder of Roman rule. Lead seals identifing the unit, from South Shields and Corbridge, were probably produced while the unit was at Halton Chesters.
