Universal casters can be divided into two categories based on their functions: universal casters and directional casters, which are often used in combination to achieve flexible movement and stable positioning. The core feature of the universal wheel is the rotating bracket, which can freely turn 360 ° and is suitable for equipment that requires frequent directional changes, such as shopping carts, medical carts, office chairs, etc; Directional wheels can only roll in a fixed direction and cannot turn autonomously. They are mainly used to enhance the straight-line driving stability of equipment and are often installed on the rear or both sides of the bottom of the equipment. They work together with universal wheels to form a classic combination of "front universal+rear directional", such as luggage, logistics turnover vehicles, etc. According to the installation method, it can be classified into three types: flat plate type, screw type, and plug-in type. The flat plate type is directly fixed to the bottom of the equipment by screws, with strong load-bearing capacity and suitable for heavy equipment; Screw type with threaded screw, adjustable height and fastening, suitable for uneven ground scenes; Plug in type quick installation and disassembly through pins, commonly used for light tool vehicles or temporary equipment. In addition, according to the carrying capacity level, it can be divided into light (≤ 100kg), medium (100-500kg), heavy (500-1500kg), and super heavy (≥ 1500kg). Light is suitable for home and office scenarios, while heavy is used for industrial equipment, storage shelves, etc.

Common faults and troubleshooting solutions
During the use of universal wheels, it is easy to encounter problems such as rotational lag, increased noise, rapid wear on the wheel surface, and brake failure. Timely troubleshooting and resolution can prevent the expansion of the problem and ensure safe use.
The core misconceptions and correct methods of selection
Many users are prone to falling into the trap of "only looking at the price" and "ignoring the scenario" when choosing universal wheels. The correct selection should follow the logic of "setting requirements first, then selecting parameters" to avoid poor user experience or safety hazards caused by improper selection.
