Provided is a bearing arrangement for a wind turbine, including a first portion, a second portion, and a sound wave sensor which is configured to detect a thickness of the second portion, wherein one of the first portion and the second portion is movable relative to the other of the first portion and the second portion. In contrast to known bearing arrangements for wind turbines, the thickness of the second portion which for example is exposed to wear may be actively detected. Thus, the information of the thickness is available at any time. Thus, a demand of an exchange of the second portion can be precisely predicted and determined.

Bearing arrangement and a wind turbine

A spherical body inspection apparatus including a support arrangement realized to support a spherical body during an inspection procedure; a probe arrangement comprising a plurality of ultrasonic testing probes arranged about the spherical body such that the ultrasonic testing probes target a common test point at the surface of the spherical body; and a displacer for effecting at least one relative rotational displacement between the spherical body and the probe arrangement. Also described is a method of inspecting a spherical body.
