A 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 wheels, turning them into moving or portable carts.

Then what are universal and fixed casters? A versatile 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 the wheel is mounted on the fixed frame and moves straight with the installed object.

Although castors can be divided into industrial, medical, and equipment castors according to their different uses, they are not allowed to be installed on the same equipment. However, universal 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 moving trolley is the most common form of matching use of the non-directional and universal wheel. Its front end is equipped with two universal wheels, and the back end is fitted with two fixed wheels so the cart can walk on the road flexibly. However, it is impossible to continue walking flexibility by assembling this way. Many factors affect casters' walking flexibility, such as the bracket's structure, the bracket steel's selection, the wheel's size, the wheel's type, the bearing, etc., and the choice of caster material. The complex and narrow wheels are more labor-efficient on the flat ground than the bland and soft wheels. But smooth wheels can better protect equipment and shock absorption on uneven ground.

Understanding the nuances of trolley wheels can significantly improve the efficiency and lifespan of your equipment. Different applications require specific types of spins, and choosing the right fit is crucial. As noted by Caster Central, various casters and wheels are designed for particular surfaces, weight capacities, and environments, ensuring optimal performance. It's essential to make informed decisions to ensure the longevity and effectiveness of your trolley or cart.

At present, the primary materials of caster wheel products of flat handcarts 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 polyurethane's wear and sewage resistance, polyurethane industrial casters are primarily 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:

Nylon industrial casters have excellent heat resistance, cold resistance, wear resistance, and others, and their weight is also lighter and convenient to carry. It's more and more used in the transportation and aviation industries.
Because of the low cost of human-made and special plasticity data processing, the artificial industrial caster has the elasticity of a Rubber Caster. At the same time, it can be used generally under extreme conditions such as water resistance, cold solid 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 and strong load-bearing. They are not easy to deform, strong, silent, and more labor-saving push and pull, which can be used in all industries. If you are looking for reliable casters for your industrial trolley, HOD is the right choice.
