Caster definition and application field

What kind of product are casters? We share with you our many years of production experience, please see more!
Casters are a general term, including movable casters and fixed casters.
It is difficult to trace the history of casters, but after people invented the wheel, it became much easier to carry and move objects, but the wheel can only run in a straight line, and it is still very difficult to change the direction when carrying large objects , and later people invented the wheel with steering structure, which is what we call caster or universal wheel. The appearance of casters has brought an epoch-making revolution to people’s handling, especially moving objects. Not only can they be easily handled, but they can also be moved in any direction, which greatly improves the efficiency. In modern times, with the rise of the industrial revolution, more and more equipment needs to be moved, and casters are more and more widely used all over the world, and almost all walks of life are inseparable from casters. In modern times, with the continuous development of science and technology, the equipment has become more and more versatile and highly utilized, and casters have become an indispensable part. The development of casters has become more specialized and has become a special industry.

Casters are divided into movable casters and fixed casters. The movable casters are also called universal wheels, and their structure allows 360-degree travel; the fixed casters are also called directional casters, which have no rotating structure and cannot be rotated. Usually two kinds of casters are used in combination. For example, the structure of the trolley is two directional wheels in the front, and two universal wheels in the back near the push armrest. There are casters of various materials, such as cast iron wheels, nylon wheels, PVC wheels, TPR wheels, PU wheels, rubber wheels, PP wheels, etc. Caster subdivision: super heavy-duty casters, extra-heavy-duty casters, special-shaped casters and brake casters, shock-absorbing casters, adjustable casters and light-duty casters, medium-duty casters, heavy-duty casters, etc.
Structural features: Installation height: refers to the vertical distance from the ground to the installation location of the equipment, and the installation height of the caster refers to the maximum vertical distance from the bottom of the caster and the edge of the wheel. Bracket steering center distance: refers to the horizontal distance from the vertical line of the center rivet to the center of the wheel core. Turning radius: refers to the horizontal distance from the vertical line of the central rivet to the outer edge of the tire. The appropriate distance enables the caster to turn 360 degrees. Whether the turning radius is reasonable or not directly affects the service life of the caster. Driving load: The load-bearing capacity of the caster when moving is also called the dynamic load. The dynamic load of the caster varies depending on the test method of the factory and the material of the wheel. The key is whether the structure and quality of the bracket can resist shock and impact. shock. Shock load: The instantaneous load-bearing capacity of the caster when the equipment is impacted or vibrated by the load. Static load Static load Static load Static load: The weight that the caster can bear in a static state. The static load should generally be 5 to 6 times the exercise load (dynamic load), and the static load should be at least 2 times the impact load. Steering: Hard, narrow wheels are easier to steer than soft, wide wheels. The turning radius is an important parameter for wheel rotation. If the turning radius is too short, it will increase the difficulty of steering, and if the turning radius is too large, it will cause the wheel to shake and shorten its life. Driving flexibility: The factors that affect the driving flexibility of casters include the structure of the bracket and the selection of steel for the bracket, the size of the wheel, the type of the wheel, the bearing, etc. The larger the wheel, the better the driving flexibility, and it is hard and narrow on a stable ground. Wheels are more labor-saving than flat-sided soft wheels, but on uneven ground, soft wheels are less labor-intensive, but on uneven ground, soft wheels can better protect equipment and absorb shocks!
Its application industries: industry, commerce, medical equipment and machinery, logistics and transportation, environmental cleaning products, furniture industry, beauty equipment, food machinery, hardware production and other industries.
