An antifriction linear ball bearing assembly comprises a trihedral cassette (10) with flats (24, 26, and 28), and a central opening for rigidly holding a cylindrical shaft. The cassette (10) has flats which each contain a closed raceway circuit (36) having an elliptical shape. The raceway circuit is filled with bearing balls (14), kept within their track by a ball retainer (12). When the bearing assembly and the shaft, mounted into it, are translated inside an outer sleeve, the bearing balls (14) circulate within the raceway circuits, thus allowing smooth longitudinal movement of the shaft and ensuring uniform wear of the contact surfaces. The linear ball bearing assembly can be applied to mechanisms, such as a motion transmitting device or a feedthrough apparatus, where a shaft supported by antifriction bearings must longitudinally translate inside a hollow outer housing.
