A novel experimental arrangement is proposed which allows fast and repeatable measurements of the running torque of tapered roller bearings under combined axial and radial loading. Its principles of operation are explained and experimental results presented over a large range of speeds and under different lubrication conditions. By permitting direct torque readings, this arrangement allows rapid comparison between the performance of tapered roller bearings and developmental bearings for which there are no current theoretical torque formulae available. Comparisons are made between the results and a standard torque prediction model for tapered roller bearings. Limited agreement is observed.
