Flat wheels are wheels that have a flat or flat surface and are usually made of materials such as metal or plastic. Its features include:
1. Strong bearing capacity: the flat surface of the flat wheel can bear more weight, so its bearing capacity is relatively strong.
2. Small resistance: Because the surface of the flat wheel is relatively flat, friction and resistance can be reduced during exercise, so the exercise is easier and smoother.
3. Wide applicability: Flat wheels can usually be used in various occasions and environments, such as furniture, rail vehicles, logistics equipment, etc.
4. Strong wear resistance: Flat wheels are usually made of metal or hard plastic and other materials, which have strong wear resistance.
5. Easy to install: the flat wheel can usually be fixed on the equipment by bolts or pins, etc., and the installation is relatively simple.
In short, flat wheels have the characteristics of strong bearing capacity, small resistance, wide applicability, strong wear resistance, and easy installation, so they are widely used in various occasions.
