Caster, generally composed of a single wheel and bracket, is installed under the equipment to enable it to move freely. Casters are divided into universal casters and fixed casters according to different purposes. Commonly, most trolleys would have the wheels, turning it into a moving or portable cart.

Then what are universal and fixed casters? Universal caster means that the wheel is installed on the rotating bracket and can rotate 360 degrees in its horizontal direction. The non-directional caster means that the wheel is mounted on the fixed bracket and moves in a straight line with the installed object.

Although castors can be divided into industrial castors, medical castors, and equipment castors according to the different uses, they are not allowed to be installed on the same equipment in fact. But universal castors and fixed castors can be reasonably mixed and configured according to the prior design. Generally speaking, non-directional castors and universal castors are used together.

The most common form of matching use of the non-directional wheel and universal wheel is the moving trolley. Its front end is equipped with two universal wheels, and the back end is fitted with two fixed wheels so that the cart can walk on the road flexibly. However, it is not possible to continue walking flexibility by assembling in this way. Many factors affect the walking flexibility of casters, such as structure of the bracket and selection of the bracket steel, size of the wheel, type of the wheel, the bearing, etc. , also the choice of caster material. On the flat ground, the hard and narrow wheels are more labor-efficient than the flat and soft wheels. But on uneven ground, smooth wheels can better protect equipment and shock absorption.

At present, the primary materials of caster wheel products of flat handcart include polyurethane, cast iron, cast steel, NBR, natural rubber, silicon fluorine rubber, neoprene rubber, butyl rubber, silicon rubber, EPDM, Viton, HNBR, etc.

Rubber castors:

As one of the most frequently used castors in the rubber industry, due to the particular material of rubber, it is elastic and has excellent skid resistance, compared with the primary characteristics of the friction coefficient in the air. The castors can be safely used when transporting goods and are widely used indoors.

Polyurethane caster:

Due to the wear resistance and sewage resistance of polyurethane, polyurethane industrial casters are mostly used in environmental protection and dust-free industries. The friction coefficient of polyurethane to air is relatively small. So the music coefficient is low in the application process, which has become the first choice of many environmental protection industries.

Nylon Caster:

Not only nylon industrial caster has excellent heat resistance, cold resistance, wear-resistance, and others, but also its weight is lighter, convenient to carry. It's now more and more used in the transportation industry, the aviation industry.
Because of the low cost of human-made and special plasticity data processing, the artificial industrial caster itself has the elasticity of Rubber Caster. At the same time, it can be used generally under extreme conditions such as water resistance, strong cold resistance, and low-temperature resistance. It is also a caster widely used in the application.

Application industry

Industry, commerce, medical equipment and machinery, logistics and transportation, environmental protection and cleaning products, furniture industry, beauty equipment, food machinery, hardware production, and other industries.

HOD trolley wheels are all made of PU castors with good elasticity, strong load-bearing. They are not easy to deform, strong, silent, more labor-saving push and pull, which can be used in all industries. If you are looking into the reliable casters for your industrial trolley, HOD is the right choice.
