A portable coordinate measuring machine comprises a multijointed manually positionable articulated measuring arm for accurately and easily measuring a volume. The articulated arm includes a plurality of bearing arrangements comprising at least a pair of spaced bearings, the spaced bearings being pre-stressed such that, under an applied load, any motion of the arm is limited to axial motion and wherein the mechanical stability of the arm is increased.
