摘要： A device for breaking solid material comprises an expansible hose element which is insertable into a hole in the solid material and has an externally substantially geometrically regular cross-section. At least at one of its ends, the hose element comprises a coupling. The device further comprises at least one expansion portion with an expansion chamber. The hose element further comprises an expansion limiter which has a varying radial distance from the outside of the hose element along the circumferential direction of the hose element.

摘要： A rolling bearing for journalling an outer machine component (12) for rotary movements in relation to an inner machine component (13). For connection to at least one of the machine components, the bearing comprises corresponding outer and inner main elements, respectively, in the shape of a helical spring (14/15), which is wound to form parts (16/22) supporting rolling surfaces for the rolling bodies (17) of the bearing, which rolling bodies are arranged in an annular raceway. The spring is wound from said supporting part so that it forms a connection part (19/24) in at least one axial direction. These connection parts are arranged to connect and join with further operative parts of the bearing. Examples include parts for connecting the supporting part in question for said rolling surface with further such parts to form a bearing with several rows. Further functions can be to form one or several parts for the assembly and attachment of the helical spring to the respective machine component (12, 13), such as a seat in the outer machine component or an outer envelope for a shaft belonging to the inner machine component.
