Low-friction sliding chute and main cable saddle system

The invention relates to a low-friction sliding groove and a main cable saddle system, the low-friction sliding groove is an engineering plastic alloy component, the low-friction sliding groove is arranged in an arc shape in the length direction of the low-friction sliding groove, the middle of the low-friction sliding groove is high, the two ends of the low-friction sliding groove are low, and the low-friction sliding groove is used for steering of a main bearing cable. According to the low-friction sliding chute disclosed by the invention, the characteristics of large bearing capacity, high compression resistance, high wear resistance, corrosion resistance, good toughness, low friction coefficient, self-lubrication, no maintenance and long service life of the engineering plastic alloy are utilized, and the low-friction sliding chute is used for replacing a traditional cable saddle pulley; the problems that the pulley is easy to damage and difficult to replace and the friction of the pulley is gradually incr
