Abstract
A reciprocating shaft assembly in a reciprocating saw moves in a reciprocal motion and drives a saw blade via a blade holder. At least one bore is formed in an end of the reciprocating shaft assembly opposite the blade holder. A pin fixed to the saw passes through the bore and acts as a bearing to support the reciprocating shaft assembly in its reciprocating motion.
