Making principle of universal wheel for luggage

Its structure allows horizontal 360-degree rotation. Casters are a general term, including movable casters and fixed casters. The fixed caster has no rotating structure, so it can't rotate horizontally, but only vertically. These two casters are generally used together. For example, the structure of the car is two fixed wheels in the front and two movable universal wheels near the armrest at the back.

Casters must be installed in the design position specified by the manufacturer. The installed caster bracket must have sufficient strength to meet the bearing capacity when in use. The function of casters cannot be changed, and it is not affected by the installation equipment. The axis of rotation must always be vertical. The fixed caster must be in a straight line with its axis. If only rotating casters are used, they must be consistent.

Extended data:

Universal casters can be selected at 360 degrees, while directional casters can only travel in a fixed direction. Usually fixed casters and universal casters are used together. Serious damage or looseness of rubber tires may lead to rolling instability, air leakage, abnormal load and floor damage. Replacing damaged tires and bearings in time can reduce the cost loss caused by downtime due to damaged casters.

When selecting the material of universal wheel, we should first consider the size of the road surface, obstacles, residual substances (such as iron filings and grease) at the use site, environmental conditions (such as high temperature, normal temperature or low temperature) and the weight that the wheel can bear, so as to determine the appropriate wheel material.

For example, rubber wheels cannot resist acid, grease and chemicals, while super polyurethane wheels, high-strength polyurethane wheels, nylon wheels, steel wheels and high-temperature resistant wheels can be applied to different special environments.
