Abstract: A bearing test apparatus for testing a bearing (hereinafter, referred to as a “test bearing”) has a chamber, a bearing cap disposed in the chamber and coupled to an outer wheel of the test bearing, a driving shaft connected to an inner wheel of the test bearing to rotate the inner wheel, an extension arm extending in a radial direction of the bearing cap from the bearing cap to expose one end thereof out of the chamber, and a measurement arm configured to make a contact with one end of the extension arm and configured to be rotatable by the extension arm, wherein an exclusive torque of the test bearing is obtained by measuring a force applied to the measurement arm by the extension arm when a rotation force is applied to the bearing cap by the outer wheel.
