A large open-center roller bearing consisting of single or multiple outer and inner rings with rollers rolling over races between the rings, wherein one ring can accommodate an ultrasonic probe and the other ring has a contact surface. The object is to provide a bearing that can be simply and reliably tested by ultrasound.
