1. The larger the diameter of the casters, the greater the size of the caster, the better the driving force, the better the obstacle, because the casters first in the late 19th century the formation of industrialization in the West, so casters generally in inches to express, such as China's supermarket trolley mostly with 5 , 4 inch casters. Currently on the market popular casters size from 1 inch to 10 inch have, commonly used size 2 inch, 2.5 inch, 3 inch, 3.5 inch, 4 inch, 5 inch, 6 inch, 8 inch, 10 inch, Need to promote, such as supermarket shopping carts, logistics trolleys, tool carts, etc. 4 to 6 inch casters better. But the caster diameter is too large will make the equipment center of gravity rise, the cost increases, so to be considered. If the equipment does not need to often promote, such as furniture, refrigerators, etc., can choose the following 3-inch casters. 2. Look at the load: the same diameter of the casters, the general manufacturers will produce several series for different load-bearing, such as light, medium, medium, etc., is to make the wheels and stents have different thickness or material. When the load of a single casters to give a certain degree of insurance factor, when the ground is relatively flat, a single casters load = (total equipment ÷ installed the number of casters) × 1.2 (insurance factor); if the ground is not flat, the algorithm is a single Casters load = total weight ÷ 3, because no matter what kind of non-flat ground, always at least three wheels at the same time support the device, this algorithm is equal to increase the insurance factor, more reliable, to prevent load-bearing, resulting in greatly reduced or lead casters ACCIDENT. In foreign companies, the load is generally expressed in pounds, while the domestic most of the kilograms, they conversion relationship is: 2.2 pounds = 1 kg. 3. Wheel material: This is very important, generally PU, TPR, PP, rubber, nylon, etc., as for the temperature, surface hardness, the ground environment. 4. Installation: General light load available screw, plunger, expansion sleeve, etc., heavy load with the floor, or directly welded to the device. 5. Brakes: from the function, there are brake wheels, there are brakes universal, both with the brake was double brake, there are tread brake, the moment brake, side brake and so on. 6. Bracket selection: divided into oriented and universal, the material generally with carbon steel, can be a variety of electroplating, such as galvanized, copper, nickel, chrome, spray, etc., also useful stainless steel.
