What is the relationship between the size of the caster and carrying capacity?

Universal wheel, adjusting the diameter of the foot manufacturers casters size and what is the relationship between bearing capacity? Caster wheel bearing ability, also known as dynamic load in caster wheel dynamic load because of the size of the diameter of different and different, also because of the factory test in a different way is different, the wheel material different dynamic load will also vary. Caster wheel diameter is caster wheel rotation is an important parameter, short turning radius increases to the difficulty, too much will cause the wheels wobble and shorten the life. Usually caster wheel diameter the more the more easy to drive, the greater the load capacity and at the same time, it is to protect the surface from being damaged, wheel diameter size selection of first consideration should be given to carrying equipment weight and dynamic load under the move tool starting thrust to decide.
