Abstract

A test stand for testing a bearing with a first bearing ring and a second bearing ring includes a rotatable drive flange for driving the first bearing ring, a holding bearing for supporting the bearing and for introducing a testing force into the bearing, and a drive motor. The holding bearing includes a first support ring arranged to be secured to the second bearing ring, a second support ring secured in a rotationally fixed manner, and an intermediate ring mounted between the first support ring and the second support ring in a relatively rotatable manner. The drive motor is coupled to the intermediate ring for rotating the intermediate ring relative to the first support ring and the second support ring. The bearing may be a wheel bearing of a motor vehicle. The first bearing ring may be an inner ring and the second bearing ring may be an outer ring.
