Disclosed is a rolling tool which serves for working&#x2014;in particular rolling smooth&#x2014;an inner lateral surface of a cylindrical clearance. For this purpose, the rolling tool has at least one rolling body, which is held in the rotatably drivable rolling tool, and can be taken along by said tool on a peripheral path along the inner lateral surface. The at least one rolling body is inserted into a radial clearance in the rolling tool and can be subjected to a pressurized fluid from the inside to the outside along the radial clearance. The fluid is an aerosol. The aerosol is a fluid mixed with gas and serves for hydrostatic bearing and lubrication.

Rolling tool

A method for separating a bearing channel of a housing by cracking. The bearing covers of the bearing channel are separated from the housing by cracking by means of a cracking mandrel. The steps include clamping the housing at the top thereof so that the bearing channel is downwardly oriented, i.e., towards a supporting or clamping surface of the housing and supporting the bearing cover during separation by cracking by means of a counter bracket.
