Polyurethane caster diameter is an important parameter for caster rotation. If the turning radius is too short, it will increase the difficulty of steering, and if it is too large, it will cause the wheel to shake and shorten the life. Generally, the larger the caster diameter is, the easier it is to push, and the larger the load capacity is, the more it can protect the ground from damage. The selection of the wheel diameter should be determined by considering the weight of the equipment to be carried and the starting thrust of the mobile tool under dynamic load.
Installation height: refers to the vertical distance from the ground to the installation position of the equipment. The installation height of polyurethane casters refers to the vertical distance from the bottom of the casters to the sides of the wheels. Bracket turning center distance: refers to the horizontal distance from the vertical line of the center rivet to the center of the wheel core. Driving flexibility: The factors that affect the driving flexibility of casters are the structure of the bracket and the choice of bracket steel, the size of the wheel, the type of wheel, and bearings. The larger the wheel, the better the driving flexibility. Hard, narrow wheels save effort on smooth ground than soft wheels with flat edges, but soft wheels save effort on uneven ground, but soft wheels can better protect equipment and avoid shock! Turning radius: refers to the horizontal distance from the vertical line of the center rivet to the outer edge of the tire. The proper spacing allows the polyurethane casters to turn 360 degrees. Reasonable rotation radius directly affects the service life of polyurethane casters
