    Abstract: A device and a method for measuring and indicating the static torque of a tapered roller bearing under varying axially applied loads. The device includes a base having a surface for supporting the cone of a tapered roller bearing, a fixture for engaging the cup of the tapered roller bearing when it is located on the base supporting surface. The fixture is mounted for linear movement with the cup relative to the cone to apply a static load to the cup. A variable static load applying mechanism such as an air cylinder is operatively connected to the fixture. A thrust applying frame which supports a thrust bearing connects the air cylinder and the fixture to uniformly transfer axial loads to the tapered roller bearing being tested. An indicating torque wrench is used to rotate the fixture and the engaged cup of the tapered roller bearing relative to the cone of the bearing under variable axial loads to determine and indicate the torque required.
