Abstract of the Disclosure A bearing arrangement for a feeding device for a drilling machine, comprising a feeding beam (1) provided with longitudinal guides (6), a carriage supporting a drilling machine (3) and provided with guide surfaces in slidable engagement with the guides, and displacing means for displacement of the carriage along the guides. At least one guide surface (5a) of the carriage is formed by a spacer (5) supported by the carriage. For automatical elimination of the clearance between the feeding beam and the carriage, the spacer is pressed against a wedging surface (8) provided on the carriage and extending essentially in parallel with the guide. The carriage is provided with means (9) for displacement of the spacer in between the guide surface (6a) of the guide of the feeding beam and the wedging surface (8) of the carriage so that the growth of clearance caused by wearing of the spacer is avoided as the wearing increases.
