The Caster's structure allows 360 degree horizontal rotation. Its tracks are wide enough to support heavy weights and allow for easy navigation over irregular terrains.
Manufacturing principle of universal wheel of suitcase
Its structure allows 360 degree horizontal 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 and can only rotate vertically. These two kinds of casters are generally used together. For example, the structure of the trolley is two fixed wheels in the front, and two movable universal wheels close to the push handrail in the rear.
The universal wheel must be installed at the position indicated by the manufacturer. The installed caster support must have sufficient strength and conform to the load-bearing capacity during use. The function of castors cannot be changed and is not affected by the installation device. The rotating axle must always be vertical The fixed casters must be in line with their axles. If only rotating casters are used, they must be consistent.
Universal casters can be selected 360 degrees, while directional casters can only drive 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 bottom plate damage. Timely replacement of damaged tires and bearings can reduce the cost loss caused by downtime due to caster damage.
When choosing castor material, first of all, consider the size of the road, obstacles, residual substances on the use site (such as iron filings and grease), the environmental conditions (such as high temperature, normal temperature or low temperature) and the weight that the wheel can carry, and other different conditions to determine the selection of suitable 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 wheels can be applied to different special environments.
What are the conditions for the directional wheel and universal wheel of the suitcase?
Half of the directional wheel is often embedded in the box, which makes the box can only move back and forth, and cannot turn in place. The biggest advantage of the directional wheel is resistance, even if the road is full of gravel, so if your suitcase often "walks" on an uneven road, the use time of buying the directional wheel may be longer.
The 4-wheel universal wheel is often referred to as the universal wheel, which allows the box to change direction 360 ° freely, and push horizontally (4 wheels on the ground) with less effort. The disadvantage of the universal wheel is that it can't handle "barbaric treatment", so it's best to walk on a smoother road when holding the universal wheel box, otherwise the wheel may "strike" halfway.
The aircraft wheel is also universal, but it looks like the wheel of the aircraft, which is double row, so it has such a name. The aircraft wheel has all the advantages and disadvantages of the above universal wheel, but the two are still a little different.
Summarized as follows
Durability: unidirectional wheel > aircraft wheel > universal wheel
Smoothness: aircraft wheel > universal wheel > unidirectional wheel
Market price: aircraft wheel > universal wheel > one-way wheel
