Stihl Rollomatic E sprocketnose chainsaws bars come standard on most Stihl chainsaws. Bars are made of three steel plates that are electrically welded together. The center plate has been hollowed out to reduce weight. The nose sprocket is sealed to keep dirt and corrosive material out, therefor never needs to be greased. Rails are induction hardened for long life. This bar has relatively small nose radius which helps reduce the incident of kickback (green color coded bar) and reduces weight.
