The invention discloses a honeycomb structured ball reverser, relates to a device for making a roller chain circulate in a bent roller path in a screw and nut mechanism, and mainly solves the problems of noise caused by colliding a roll ball and the reverser, and reduction of accuracy. The honeycomb structured ball reverser comprises a honeycomb matrix and a conduit, wherein the conduit is put on the inner wall of a bending roller path in the honeycomb matrix; the honeycomb matrix is made of an engineering plastic material; and the conduit is a steel pipe. The honeycomb structured ball reverser can reduce the friction and collision between the roll ball and the reverser, can make the roller chain circulate in the bent roller path more smoothly, and also has the noise reduction function.
