A bearing apparatus for mounting a camshaft in a cylinder head of an internal combustion engine may include a bearing element that surrounds a bearing ring in which the camshaft is rotatably mounted or mountable. The bearing element may be made of a first material whose expansion coefficient is greater than an expansion coefficient of a second material of which the bearing ring is made. An outer surface of the bearing ring may include a contour that engages in a form-fitting manner with a mating contour formed on an inner surface of the bearing element that surrounds the bearing ring. The contouring formed by the contour and the mating contour may form retaining structures that brace against one another in instances of thermal expansion.

A tilting-pad bearing for rotatably supporting a rotor includes: a casing; and a plurality of bearing pads each mounted to the casing pivotably about a pivot. Each of the plurality of bearing pads has a bearing pad surface facing the rotor, the bearing pad surface including a first region disposed on an upstream side in a rotational direction of the rotor and having a first curvature radius, and a second region disposed on a downstream side of the first region in the rotational direction and having a second curvature radius smaller than the first curvature radius.
