Sep 25 , 2020What is the difference between casters and wheels?
A wheel is a round rolling object made of different materials. It is usually a pie, or it can be seen as a flat cylinder with a concentric hole in the center, or it can be seen as a torus. The wheel can be a solid ring or a hollow ring. Subject to various factors such as weight and cost, the daily performance is more of a hollow ring, that is, our common wheel, which includes the outer ring of the wheel, the spokes connected to the outer ring and the central shaft. By rolling, the wheel can greatly reduce the coefficient of friction with the contact surface. If equipped with axles, it becomes the most important part of the car. Wheels are very useful in transportation and are one of the important inventions of mankind.
Casters are a collective term, including swivel caster wheels, fixed caster wheels and swivel brake caster wheels. Swivel casters are also what we call universal wheels. Its structure allows 360-degree rotation; Swivel casters with brakes are also universal wheels and can also be rotated in any direction; fixed casters are also called directional casters, which have no rotating structure and cannot change the direction.The direction of rotation can only be rolled in two fixed directions forward and backward. Usually two types of casters are used in combination. For example, the structure of a plastic folding platform hand trolley has two heavy duty nylon fixed caster wheels at the front, and two swivel casters at the back, which are close to the push armrest. Caster wheels are made of various materials, such as PP casters, PVC casters, PU casters, cast iron casters, nylon casters, TPR casters, Aluminium core rubber casters, iron core PU casters, etc.
In this way, we can understand that wheels are an important part of casters and are accessories of casters; casters are wheels with mounting brackets and steering system.
Casters are used in a wide range of industries, including industrial, commercial, medical equipment, machinery, logistics and transportation, environmentally friendly cleaning products, furniture, electrical appliances, beauty equipment, mechanical equipment, craft products, pet supplies, hardware products and other industries. According to these application scenarios, casters are divided into three categories, industrial casters, furniture casters and medical casters.
