Abstract

A bearing system in rotary drill bits for rotatably carrying a roller cutter (12) on a bearing shaft (11) comprises a bearing element (14) connected to the roller cutter or the bearing shaft. For purposes of rigidly connecting the bearing element (14) to the roller cutter (12) or the bearing shaft (11) the bearing element (14) is adapted to be wedgingly secured the roller cutter (12) or the bearing shaft (11) upon a limited turning of the bearing element (14) relative to the roller cutter (12) or the bearing shaft (11).
