Summary:The present disclosure relates to a cutter assembly for an undercutting machine for cutting a rock workface and a method of disassembling a cutter assembly. The cutter assembly includes a shaft supporting structure, a shaft at least partly arranged within the shaft supporting structure, a cutter device arranged on the shaft or the shaft supporting structure, a first rolling element arranged between the shaft supporting structure and the shaft in a floating or slidable manner in an axial direction, and a second rolling element arranged between the shaft supporting structure and the shaft. A line orthogonal to an outer surface of the second rolling element crosses the longitudinal axis of the shaft at a center plane of the first rolling element or within a range of +/−25% of an axial extension of the first rolling element from the center plane.
