An adjustable camshaft for a valve drive of an internal combustion engine may include an inner shaft extending through an outer shaft with a cam element disposed on the outer shaft. The cam element may be connected rotationally conjointly to the inner shaft. The cam element may have a shaft passage with an internal bearing surface, which, together with a bearing surface on an outer side of the outer shaft, forms a plain bearing arrangement for the rotatable arrangement of the cam element on the outer shaft. The bearing surface on the outer side of the outer shaft and/or the internal bearing surface of the shaft passage of the cam element may include one or more sections with a spherical shape. |
