Heavy-duty casters: Choose the right ones, and moving heavy objects will be easier
Time：May 24,2025
Heavy-duty casters, as the name suggests, are specifically designed to carry heavy loads. They are mainly used for transporting heavy equipment or particularly heavy items. Generally, the load capacity of such casters ranges from 500 kilograms to 15 tons, or even higher.
Caster Bracket Structure
The brackets of heavy-duty casters are mostly made of metal, using methods such as ordinary steel plate stamping, cast steel molding, and die-forged steel molding. They are usually assembled using a flat plate assembly method.
The thickness of the steel plate used for the caster bracket is also important, generally 8 mm, 10 mm, 16 mm, and even more than 20 mm. This is to ensure that the caster has sufficient strength and stability and will not easily deform or be damaged.
Swivel Caster Plate Design
The design of the swivel plate for heavy-duty casters is also carefully considered. Generally, a double-layer steel ball track is used, which is stamped and then heat-treated to improve its load capacity. For extra-heavy-duty swivel casters, the swivel plate will use higher load-bearing planar ball bearings or planar needle roller bearings, and will also be equipped with tapered roller bearings, thus further enhancing the caster's load capacity. For heavy-duty swivel casters that need to withstand impact, the swivel plate will be made of die-forged steel, directly molded, avoiding the trouble of connecting plate bolt welding and greatly improving the impact resistance of the caster.
Characteristics of Heavy-Duty Casters
The biggest feature of heavy-duty casters is their ability to withstand very heavy weights, easily handling loads from 500 kilograms to 15 tons or even more.
The choice of materials for heavy-duty casters is also crucial. Because they are used to move heavy equipment, high-strength materials such as cast steel, cast iron, or alloy steel are generally used to ensure sufficient load-bearing capacity and durability.
The material of the wheel is also critical. The wheels of heavy-duty casters are mostly hard-tread single wheels, commonly including nylon wheels, cast iron wheels, forged steel wheels, hard rubber wheels, polyurethane wheels, and phenolic resin wheels. Among them, forged steel wheels and polyurethane wheels are particularly suitable for extra-heavy-duty casters.
The diameter of the wheel is also important. The larger the wheel diameter, the more flexible the rotation. Common specifications include 4 inches, 5 inches, 6 inches, 8 inches, 10 inches, and 12 inches. Extra-heavy-duty casters can also use 16-inch and 18-inch wheels.
In addition to these, some heavy-duty casters also have special functions, such as impact resistance, high-temperature resistance, or low-temperature resistance, which can be selected according to different usage needs.
How to Choose Suitable Heavy-Duty Casters?
When choosing heavy-duty casters, first consider the load requirements. Select based on the maximum weight of the equipment or item; otherwise, if the caster cannot handle the load, problems may easily occur.
Secondly, consider the ground conditions. For example, whether it is used on soft ground or in high-temperature or low-temperature environments, these will affect the performance of the caster.
Also, consider the usage environment, such as whether it is used outdoors or in a humid environment. These factors must also be taken into account.
How to Choose a Heavy-Duty Caster Manufacturer
Many manufacturers in China produce casters, and the quality varies. Therefore, when choosing a heavy-duty caster manufacturer, do not only consider the price; otherwise, if the quality of the caster is not up to standard and damages the load, the losses will be significant.
Choosing a professional heavy-duty caster manufacturer can be based on these aspects: Reputable manufacturers generally provide drawings and technical parameters; they will also have professional testing equipment, such as caster running tests and load tests, to ensure the quality of the casters.
Application Scenarios of Heavy-Duty Casters
Heavy-duty casters are widely used in industrial fields, and are indispensable for equipment and transportation tools such as forklifts, shelves, and workbenches.
In logistics centers, heavy-duty casters also play an important role, essential for handling heavy materials and long-distance transportation.
Summary
Choosing the right heavy-duty caster is crucial; it ensures the normal operation of equipment or tools and extends their service life. When choosing, be sure to comprehensively consider load requirements, ground conditions, usage environment, and special functions to find the most suitable caster.
