How To Choose Castors

What should we pay attention to when choosing a caster manufacturer?

Firstly, what we must pay attention to is that the quality of the products produced by the factory must meet national standards, as well as the requirements of our own company, in order to help us further understand.

Secondly, the prices of products produced by manufacturers are also something we need to care about. After all, when purchasing industrial rubber tires, enterprises conduct large-scale procurement, and the budget is very limited. So, if the price is too high, it may also hinder our establishment of cooperation.

However, it should be noted that although we need to know how much the casters cost, the price of the product is related to factors such as cost. At this point, we cannot blindly pursue low prices, otherwise buying inferior products would be beyond our reach.

When choosing industrial casters, you only need to choose the appropriate price range, specifications, and models based on your actual situation.

Faced with numerous casters, we need to consider the size of the casters. Generally, the larger the diameter of the casters, the more effortless they are pushed, and the better their obstacle ability. Because casters first formed industrialization in the late 19th century in the West, casters are generally expressed in inches. For example, in China, supermarket carts mostly use 5-inch or 4-inch casters. At present, the popular sizes of casters in the market range from 1 inch to 10 inch. Commonly used sizes include 2 inch, 2.5 inch, 3 inch, 3.5 inch, 4 inch, 5 inch, 6 inch, 8 inch, 10 inch, etc. Generally, it is recommended to use 4-6 inch casters for supermarket shopping carts, logistics carts, tool carts, etc. However, if the diameter of the casters is too large, it will cause the center of gravity of the equipment to rise and increase costs, so comprehensive consideration should be taken. If the equipment does not need to be frequently pushed, such as furniture, refrigerators, etc., but only needs to be moved during hygiene, use casters less than 3 inches.

Furthermore, it is also necessary to consider the load-bearing capacity. For casters of the same diameter, manufacturers usually produce several series for different load-bearing purposes, such as light, medium, and medium-sized. The method is to make the wheels and brackets have different thicknesses or materials. When calculating the load of a single caster, a certain safety factor should be given. When the ground is relatively flat, the load of a single caster=(total weight of the equipment ÷ number of casters installed) × 1.2 (insurance coefficient); If the ground is uneven, the algorithm is that the load on a single caster equals the total weight of the equipment ÷ 3, because regardless of the type of uneven ground, 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, greatly reducing the lifespan of the casters or leading to accidents. In foreign-funded companies, the load-bearing capacity is generally expressed in pounds, while in most cases in China, it is expressed in kilograms. Their conversion relationship is 2.2 pounds=1 kilogram.

In addition, it is also important to pay attention to the material of the casters, which is very important. We need to choose the casters that are suitable for our own use based on our actual situation. The function of the brake and so on also depend on the specific situation of the equipment.
