1. The history of casters

Wheels are an important part of casters, and records of their use can be traced back to around 3500 BC when pottery workers used wheels. This is a simple rotating disc used by Mesopotamian pottery workers in Southwest Asia to create smooth circular clay pots. About 300 years later, the Mesopotamians learned how to install wheels on cars, marking the beginning of the era of wheeled transportation. Wheels began to be widely used in ancient times, with the earliest wheels being solid wooden wheels on horse drawn carriages. Put two or three wooden boards together and cut them into a circle. They first appeared around 3200 BC. And wheels with spokes began to appear around 2000 BC. This type of wheel is lighter and faster than solid wheels, making it suitable for use on tanks. Wheels made of iron wire as spokes appeared around 1800, they were lightweight and sturdy. This type of wheel was first used in cars, bicycles, and early Yueji. In the 1950s, the iron wire wheels on cars were replaced by metal wheels.

With wheels, movement has become easier, but the flexibility of wheel rotation directly affects people's work intensity in object handling. There are many important factors that affect the flexibility of wheel rotation, among which the axle and bearing are one of the important factors that affect the flexibility of wheel rotation. The wheel rotates on the axle. Wheels usually have ball bearings, needle roller bearings, etc.

2. The invention of casters
With the invention of the wheel, it has become much easier to transport and move objects. However, the initial wheels could only run in a straight line, and it was still very difficult to change direction when transporting heavy objects. Later, smart people invented wheels with steering structures, which are commonly known as caster brackets. The caster brackets are usually made of steel plate stamping, or integral cast steel molding, or nylon plastic injection molding. According to the design of the caster bracket, we can divide them into directional casters and universal casters. Directional casters are suitable for linear movement, and universal casters are casters that can rotate 360 degrees horizontally. These casters and universal casters have brought about a revolution in the era of transportation, especially for moving objects. They can not only be easily transported, but also can be used with any other type of caster. Directional movement greatly improves efficiency.

3. Application and development trend of casters.

With the rise of the Industrial Revolution in modern times, more and more equipment needs to be moved, and casters are becoming increasingly widely used around the world. Almost all industries cannot do without casters. In modern times, with the continuous development of technology, due to the multifunctionality and high utilization requirements of equipment, casters have become indispensable components, and the development of casters has become more specialized. The caster and swivel wheel manufacturing industry has thus become a special industry. The application of casters has become more widespread, involving almost any industry. According to the needs of different industries, people need to constantly invent various types of casters. There are about 15000 different types of casters used in various industries and fields such as furniture, furniture, industry, agriculture, logistics, warehousing, docks, and defense technology around the world.
