The hanging wheel in metal door accessories is an important component of moving doors (such as those in balconies, kitchens, restaurants, and other places), playing a buffering and closing role. The main function of the suspension wheel is to lift the door leaf, bear the weight of the door on the wheel, and coordinate with the suspension rail to make the door easy to move. The suspension wheel has the characteristics of load-bearing, buffering closure, and smooth movement, which can effectively reduce friction, protect door leaves and frames, and extend the service life of mobile doors. The structural design of suspension wheels is diverse, which can meet different scenarios and needs. The material of the suspension wheel is mainly metal, with strong load-bearing capacity, wear resistance, and corrosion resistance.
