The Widespread Use Of Casters Has Had An Impact On The Development Of Our Lives

The widespread use of casters not only promotes social progress, but also has a significant impact on the development of our lives; For example, the casters in our furniture, chairs, and some large machinery in industry have now been equipped with casters for ease of movement. It can be imagined how much convenience the use of casters has brought us. Among the casters we see in our daily lives, they are not ready for use after production. They have also undergone a series of tests before being able to be boxed, packaged, and used.

The application of casters is very extensive, involving almost any industry. According to the needs of different industries, people continuously invent various types of casters, with approximately 150000 different casters used in various industries worldwide.

They are installed on instruments, furniture, transportation systems, or similar products and can be moved.

Specifically, casters and universal wheels have the following application scenarios:

-Ordinary service industries: such as shopping malls, supermarkets, shopping carts, and office equipment;

-Indoor use: such as chairs and furniture;

-Industrial purposes: such as transportation equipment for medium and heavy loads;

-Health service industry: such as hospital beds and patient carts;

The reciprocating wear test of casters simulates the actual rolling situation of casters in daily use. It is divided into obstacle test and obstacle free test. During the test, no casters or other parts are allowed to detach. After the test is completed, each caster should be able to operate its normal function. After the test is completed, the rolling, axial rotation, or braking function of the casters should not be damaged. When the casters move or want to control their direction of travel, force must be transmitted to the casters through an object and overcome a certain amount of resistance. The magnitude of resistance depends on: weight, wheel diameter, wheel material, wheel surface shape, and the site conditions of the casters' rotation.

The casters should always run steadily on the ground, but that is almost a purely theoretical state. When on uneven surfaces, or when passing through thresholds, tracks, and pits, the casters will briefly leave the ground. So when they suddenly overload or when 3 out of 4 casters come into contact with the ground, they must bear the load of the entire furniture.
