An anti-pinch chainsaw bar assembly for enabling the extraction of chainsaw bars when bound or pinched during cutting includes rolling bearing members integrated into outer surfaces of the bar. The bearings are arranged in groups of at least two bearings in rolling contact with one another. At least one bearing in each group extends outwardly from each outer surface of the bar. The assembly preferably also includes wedge structures mounted on the distal end of the bar for spreading out the sides of a cut.
