Abstract

A measurement probe for use on machine tools or coordinate measuring machines has a stylus (12) mounted in a probe body (10), for displacement in each of the axes x,y,z. On each axis, the relative motion is supported by a pair of cylindrical linear bearings, which are parallel to each other and spaced apart. The bearings comprise a shaft (30) and concentric sleeve (26), between which is located a cage (28) of ball bearings. The arrangement achieves good performance in a relatively small housing.
