The bearing (1) for the vane assembly of cooling fans is built from plastic-steel material and constructed in one piece with a cylindrical hollow body (10) and with an outwards extending seat (14) of larger diameter. The seat has a recess with a wall with a thread, and in the recess is fitted a powerful magnet. The body of the bearing has a cavity (11) extending upwards, and several claws (12), each with a protruding point (13) which engages in a round groove in the fan's impeller shaft which is fixed in the cavity in the body. |
