The invention relates to a bearing cover (3) for a split bearing arrangement (1) which, in addition to the bearing cover (3), comprises a bearing block (2), and the bearing cover (3) has a clamping surface (5) which lies against a co-operating clamping surface (6) of the bearing block (2) when the bearing arrangement (1) is in the assembled state, and at least one projection (7) is provided on the clamping surface (5) and protruding out from it which can be pushed into the co-operating clamping surface (6) of the bearing block (2). The at least one projection (7) has a cross-section (9) which varies across its extension on the clamping surface (5) and/or is of a conical or frustoconical or pyramid or truncated pyramid shape.
