A method of and apparatus for measuring the axial displacement of a tapered roller bearing assembly which eliminates the unnecessary handling of cone assemblies. After a bearing assembly to be measured is centered on the natural vertical axis of the machine, a mandrel is inserted into the bearing to lift it above a work surface of the machine. The mandrel is provided with a flange which engages and force loads the lower cone assembly. When the mandrel has lifted the bearing assembly into abutting relationship with a downwardly spring-loaded pressure plate, a bifurcated locking means supports the cup of the bearing assembly. The force is then reduced so that the spring pressure on the pressure plate force loads the upper cone assembly. A digital readout device measures the lateral movement of the roller bearing assembly in moving between the two force loading positions. The pressure plate is preferably rotatable and the machine is programmed for a metered oil spray lubrication of the cone assemblies and cup raceways. If the digital readout is within acceptable tolerance, the cup lock is released and the bearing assembly is lowered to the work surface on the machine and ejected by the same means used to center the bearing assembly. If the digital reading is out of tolerance, the cup lock is maintained and the mandrel is withdrawn which re-deposits only the lower cone assembly and the spacer element stacked thereabove. The spacer is then exchanged and the mandrel raises the lower cone assembly and spacer into the cup for a re-measurement.
