This paper describes a sophisticated research facility for the study of roller bearings at DN values of over one million with provisions for the measurement of such parameters as cage and roller speeds, bearing torque and load, and bearing ring temperatures. Particular features of the apparatus are a laser Doppler anemometer (LDA) system, with the ability to measure an instantaneous roller speed at any position in the bearing, an infrared radiation thermometer for measuring the bearing inner ring temperature, hydrostatic mounting of the test spindle, and aerostatic bearings which insure a good axial location of the test bearing and form important elements of torque and load measuring facilities which are, at once, integral and independent.
