According to market research data, the casters market is expanding, and the global casters market has reached USD 2,523 million in 2019. As people’s requirements for quality of life and convenience continue to improve, casters are increasingly used in various fields, including office furniture, warehousing and logistics, medical equipment, household appliances, construction machinery and other fields. However, with the increase in the use of time, casters will also appear some problems, such as fixed instability, rotation is not smooth, etc., so how to distinguish between good and bad casters is a noteworthy problem. Usually casters can be distinguished from the following aspects:
First, material quality
The material quality of casters is an important factor that affects their service life and bearing capacity. Usually, the material of casters is divided into metal and plastic, metal casters usually have higher carrying capacity, while plastic casters are lighter and easier to clean. Different application scenarios and needs need to be considered in the selection of materials to achieve the best results. Compared with ordinary steel, casters made of manganese steel have been popular in the industry in recent years due to their stronger load bearing capacity and greater safety.
Second, smooth rotation
The smooth rotation of the caster is one of the important indexes of its goodness. Usually, the smoothness of casters can be determined by their bearing design and material quality. If casters do not rotate smoothly or appear to be stuck, shaking and other phenomena, then these casters may have been damaged or need to be cleaned and maintained. According to statistics, millions of casters are damaged and replaced each year due to poor rotation.
Third, fixed stability
The fixed stability of casters is very important, because if the casters are loose or unstable, it will lead to danger in the process of use. The fixed stability of casters can be fixed by screws or buckles, etc. It is usually necessary to check whether the installation of casters is stable and reliable, and whether it is easy to loosen or fall off. According to statistics, there are millions of casters damaged and accidents caused by poor fixing every year.
Four, load-bearing capacity
The load capacity of a caster is the maximum weight it can bear. Different kinds of casters have different load-bearing capacity, some light load applications can use low load-bearing capacity of the wheel, but for heavy load applications, you need to choose a higher load-bearing capacity of the caster. Usually, the load capacity of a caster is labeled on its manual or packaging for users to make their choices.
Choosing casters with high quality, stable performance, sufficient load carrying capacity and smooth rotation will ensure their service life and use. In the purchase and use of casters, you need to pay attention to the selection of appropriate materials and load-bearing capacity, to ensure that the casters are fixed and stable, smooth rotation, as well as pay attention to the maintenance of casters. Especially for the frequent use of casters, you need to regularly check its installation and fixation, clean the wheel surface and bearings to ensure its normal use. In addition, when the service life of the casters expires or obvious damage occurs, it is necessary to replace them in time to avoid accidents.
