Abstract (en)
[origin: CA3195381A1] The invention relates to a sealing geometry (22) for a mobile machine tool, for example a hand-held power tool (10), in particular for processing natural or artificial, in particular cement-containing, rocks, the mobile machine tool having a drive unit (20), the sealing geometry (22) being designed to seal an inner region (IB) of the drive unit (20) which contains lubricant (26) relative to an outer region (AB) outside of the drive unit (20). Said mobile machine tool is characterized in that the sealing geometry (22) has a non-contacting seal at least during operation of the drive unit (20). A mobile machine tool provided with such a sealing geometry (22) has an especially long service life.
