ABSTRACT:
An apparatus for checking linear dimensions of shafts comprising, a frame, a centering means connected to the frame to define a horizontal axis for supporting the shaft, a supporting device fixed to the frame, measuring groups adapted to cooperate with the shaft surfaces and connection means which connect the measuring groups to the supporting device. The connection means are adapted to allow the measuring groups to move towards and away from the shafts, along planes perpendicular to the horizontal axis, from up to down and vice versa.
