When you search for casters and swivel wheels on Baidu, you will find that there are a lot of searches for the words caster specifications and swivel wheel specifications. This shows that everyone does not understand these two words. Here, Angu Universal Wheel will discuss with you how to understand caster specifications and universal wheel specifications. I hope it will be helpful when you choose casters and universal wheels.
Generally speaking, caster specifications (swivel wheel specifications) are distinguished by caster load-bearing and caster size, and have nothing to do with caster material (polyurethane casters, nylon casters, etc.).
Generally, caster factories will produce several series for different load-bearing purposes. The general way to judge caster specifications is to look at the load-bearing capacity. Casters of the same diameter. Such as light casters, medium casters, heavy casters, super heavy casters, etc.
The method is to make the caster wheels and caster brackets have different thicknesses or materials. For the load-bearing capacity of caster specifications, a certain safety factor must be given when calculating the load of a single caster. When the ground is relatively flat, the load of a single caster = (total weight of equipment ÷ number of installed casters) * 1.2 safety factor) If the ground is uneven, the algorithm is: , single caster load = total equipment weight ÷ 3. Because no matter what kind of uneven ground there is, there are always at least three wheels supporting the equipment at the same time. This algorithm increases the safety factor, is more reliable, and prevents insufficient load-bearing, which greatly reduces the life of the casters or causes accidents. For caster specifications, in foreign-funded companies, the load-bearing capacity is generally expressed in pounds, while in China most of the casters are expressed in kilograms. The conversion relationship is 2.2 pounds = 1 kilogram.
