How to choose trolley caster wheels

Trolleys are commonly used transportation tools in our daily production and life. According to the number of trolley casters, they are divided into wheelbarrows, two-wheeled trolleys, three-wheeled trolleys, and four-wheeled trolleys. Among them, the four-wheeled plastic flat trolley has a wide range of use and is relatively simple to operate.

Then how to choose the trolley caster wheels?

In general, among the many wheel materials, each material has its advantages and disadvantages. When choosing, you should choose according to different work condition of the requirements.What's the characteristic between different materials trolley casters?

1. Nylon wheels

Nylon industrial casters have the characteristics of heat resistance, cold resistance, wear resistance, etc., and their weight is relatively light. They are widely used in the transportation industry.

2. Polyurethane wheels

Polyurethane has excellent wear resistance and sewage resistance, so it is mostly used in environmental protection and dust-free industries. Polyurethane wheels also have an advantage, that is, the noise is relatively small, because the coefficient of friction of the polyurethane material on the ground is small. The noise is low.

3. Rubber wheels

The rubber material itself has good elasticity and anti-skid properties. It can move steadily and safely when transporting goods. It has good applicability both indoors and outdoors. However, this caster has a high coefficient of friction with the ground, so it will be compared when used. Loud noise.

4. Artificial rubber wheels

Artificial casters are made of special plastic materials. They have the elasticity of rubber casters, and also have the characteristics of water resistance, cold resistance, and high temperature resistance of nylon materials. Relatively speaking, the manufacturing cost of artificial rubber is relatively low.

When installing or replacing the four-wheeled plastic flat trolley casters, how should we choose the right trolley casters?

First, according to the approved load of the trolley, usually the load of this plastic flat trolley is less than 300 kg, so the single-wheel load-bearing capacity of the caster is about 100 kg. It is recommended to use casters of 4 inches or more, because the larger the wheel, the easier it is to push and More suitable for outdoor uneven ground.

Second, according to the use occasion of the trolley casters, if it is a quieter occasion such as a floor paint workshop, an electronic workshop or a hotel, it is recommended to use TPR or polyurethane casters with a quiet effect. 

But if the trolleys are work on rough outdoor or factory ground ,it is recommended to use Nylon trolley casters,iron trolley casters or rubber trolley casters.

Third, when the above two conditions are met, it is necessary to confirm whether the installation hole distance of the casters is the same as the installation hole distance on the plastic flat trolley. Because the mounting hole distance of conventional medium-duty casters on the market is 74mm x 45mm, And some of the mounting hole distance of this plastic flatbed is 84mm x71mm. If you don’t find a suitable installation hole pitch for the medium-duty casters, you can directly replace them with heavy-duty casters, because the installation hole pitch of the heavy-duty casters is the same as that of the plastic flatbed, but the price of the heavy-duty casters is more expensive than the price of the medium-sized casters Some, but the quality is much better.

Fourth, when installing this trolley casters, it is recommended that 2 fixed wheels match 2 swivel wheels, and the swivel wheels should be installed on the side close to the handle. This installation method is better to control the direction of the trolley.
