The present invention relates to a slewing bearing. The slewing bearing includes: an outer race having a ring shape; an inner race having a ring shape coupled to an inner peripheral surface of the outer race to be rotated; a rail protruding from an outer peripheral surface of the inner race, arranged along the circumferential direction, and having both side surfaces recessed inwards such that receiving grooves are formed; a plurality of rolling bodies rotatably received in both receiving grooves of the rail to cause the outer race to be in rolling contact with the inner race; and a plurality of rollers rotatably mounted along the circumferential direction between an outer peripheral surface of the rail and the outer race to be triangularly arranged with the rolling bodies such that the outer race is stably in rolling contact with the inner race. |
