• Material Characteristics: The bearing steel - made bearing ensures the strength and wear resistance of the door hanging wheel, enabling it to withstand the frequent opening and closing actions of the elevator door. The nylon A1013B - made wheel sleeve has good toughness, corrosion resistance, and self - lubrication.
