The wheel is the so-called activity castor, and its structure allows 360 degrees of horizontal rotation. Castors are collectively referred to as movable castors and fixed casters. Fixed casters have no rotating structure, they cannot rotate horizontally but only vertically. These two types of casters are generally used together. For example, the structure of a cart is two fixed wheels in front, and the two movable universal wheels are used to move the armrest behind.

The swivel wheel means that the bracket mounted on the caster wheels can rotate 360 degrees horizontally under dynamic load or static load.

There are many kinds of materials for the manufacture of universal wheels. The most common materials are: nylon, polyurethane, rubber, cast iron and other materials. Widely used in mining, mechanical equipment, electronic equipment, medical equipment, engineering decoration, textile, printing and dyeing, furniture, logistics equipment, warehousing, turnover vehicles, chassis, cabinets, equipment, electrical and mechanical, clean room, production lines, large supermarkets and many other Industry and various fields.

According to its different uses, bearings are divided into cores, aluminum cores, and plastic cores, ranging in size from 1 inch to 8 inches. Among them, iron cores and aluminum cores are generally heavy-duty load-bearing wheels, and brake equipment is often used. The cylinder clamps the cylinder of the cylinder and opens it, loosening the cylinder until it can easily come off. Please note that do not forcefully pull, otherwise it may damage the other parts of the chair.
