Abstract: A bearing test apparatus has a bearing cap coupled to an outer ring of a bearing to be tested (a “test bearing”), a driving rotary shaft coupled to an inner ring of the test bearing to rotate the inner ring, and a bearing torque meter for measuring a single torque of the test bearing, wherein an extension bar is formed at the bearing cap to protrude thereon, wherein the bearing torque meter includes a measurement rod configured to contact the extension bar and be fixed to support the extension bar in a direction opposite to a rotating direction of the driving rotary shaft, and a power sensor for measuring a force applied to the measurement rod, wherein the single torque of the test bearing is calculated based on a distance from the driving rotary shaft to the measurement rod and a force applied to the measurement rod.
