Abstract

The present invention relates to a multi-bearing which includes a plurality of bearings connected to one another so that even if a bearing portion on one side should be damaged, the period of bearing replacement or repair can be extended. The multi bearing comprises: a first bearing portion; a second bearing portion provided in alignment with the first bearing portion; an outer wheel provided at an outer radial direction of the first bearing portion; an inner wheel provided at an inner radial direction of the second bearing portion; and a connecting wheel integrally provided at the inside of the first bearing portion and the outside of the second bearing portion. According to the multi-bearing of the present invention, a plurality of bearings are connected, and an inner wheel and outer wheel are integrally formed between one bearing and another so that rotation is distributed to each bearing, and even if a portion of the bearings is damaged, continued rotation is possible through the undamaged bearings, enabling the period of bearing replacement and repair to be extended.
