Abstract: A bearing test apparatus for testing a test bearing, including 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. When a rotation force is applied to the bearing cap by the outer wheel, the extension arm is used to measure a force applied to the measurement arm, which is used to obtain an exclusive torque of the test bearing.
