1, different structures
The universal wheel is actually a movable caster that can rotate 360 degrees horizontally, while the airplane wheel is fixed and cannot rotate.
2. Different materials
Silent rubber wheels are mainly used for aircraft wheels, so the sound of aircraft wheels is very, very small when used. But the noise of universal wheels is higher than that of airplane wheels, because the materials used are different.
3, the stability is different
The stability of aircraft wheels is very good, and the cardan wheel is too flexible, which leads to poor stability.
4. Different applicable functions
Universal wheels are suitable for relatively stable intersections. If the road surface is stable, the wheels of the universal wheel will be flexible and it will be very labor-saving to pull up. However, if it is on a bumpy road, the universal wheel will be a bit hard. At this time, the aircraft wheel will be used. This kind of wheel is usually a little bigger, so it is very easy to pull.
