Difference is as follows:
One, the price difference between the universal wheel and the airplane wheel: in general, the airplane wheel is the use of mute rubber wheels, so basically are mute; the universal wheel using a variety of materials including mute rubber wheels, the same specifications of the airplane wheel than the universal wheel with material to be more, because an airplane wheel with 2 sides of the material, so the general Airplane wheels will be more expensive than the universal wheel, so the airplane wheel luggage will be more expensive than the universal wheel luggage.
Second, the difference between the use of universal and airplane wheel characteristics: the stability of the airplane wheel is good, because the 8 wheels in contact with the place, the stability is better than 4 wheels. But this also has a disadvantage, because the contact area with the ground is large, the friction is also large, so the efficiency of the airplane wheel is far from 4 wheels. Just for example, the 4 wheels can turn in place 15 times, while the airplane wheel can only turn 8-10 times.
The universal wheel is 4 wheels, so there is only sliding friction, pull up more flexible, but also requires good quality wheel bearings, otherwise when the box is heavier and placed for a longer period of time, the wheels may not be able to use properly.
Three, universal wheel and airplane wheel price difference: airplane wheel because it is 8 wheels, the production cost is higher than the cost of 4 wheel universal wheel. Airplane wheel luggage price is generally higher than the universal wheel 100-200 yuan, mature technology, good quality airplane wheel luggage price to be more than 500 yuan, more than 2,000 yuan expensive, some 100-300 yuan price on the market is not good enough for security.
So if you choose the low price or choose 4 wheel universal wheel, high price can choose 8 wheel airplane wheel. But although the performance of the airplane wheel is stable and adjustable, but the efficiency is not as high as the universal wheel, and the anti-drop performance is not as good as the universal wheel.
So the comprehensive evaluation, it is difficult to distinguish between the best and the worst, most of the difference is not purely technical issues, more personal preferences and habits of use to determine the lack of objective standards.
The universal wheel is the so-called movable caster, its structure allows horizontal 360-degree rotation. Caster is a general term, including movable casters and fixed casters. Fixed casters have no swivel structure, can not rotate horizontally only vertical rotation. These two kinds of casters are generally used in conjunction with, for example, the structure of the cart is the front of the two fixed wheels, the back near the push handrail is two movable universal wheel.
Universal wheel is the bracket installed in the caster wheel can be rotated horizontally 360 degrees in the dynamic load or static load.
There are various materials used to manufacture the universal wheel, the most common materials are: nylon, polyurethane, rubber, cast iron and other materials. Widely used in mining, machinery and equipment, electronic equipment, medical equipment, engineering decoration, textile, printing and dyeing, furniture, logistics equipment, warehousing, turnover trucks, chassis, cabinets, equipment, electromechanical, clean room, production lines, large supermarkets and many other industries and various fields.
Based on their different uses, bearings are divided into iron core, aluminum core, plastic core, size 1 inch to 8 inches ranging. Among them, iron core and aluminum core are generally heavy duty bearing wheels, which are often equipped with braking apparatus when used.
Correct use:
1, casters must be installed in the manufacturer to indicate the location of the design.
2, the installation of the caster bracket must be strong enough to comply with the use of the load-bearing capacity.
3, the function of the casters can not be changed, and is not affected by the mounting device.
4. The axle of the transit wheel must always be vertical.
5, fixed casters must be in a straight line with their axles.
6, if both only use swivel casters, they must be consistent.
7. If fixed casters are used in conjunction with swivel casters, then all casters must be compatible with each other and must be recommended by the manufacturer.
