Many people focus a lot of energy on parameters such as wheel diameter, material, and load-bearing capacity when purchasing industrial casters, but overlook an important factor that determines whether the casters can be installed smoothly – the installation method.
In practical work, we often encounter situations like this:
Although the wheel diameter, load-bearing capacity, and material all meet the requirements, it was discovered after receiving the goods that they cannot be installed; Or if the installation is barely completed, it may become loose, shake, or even affect the stability of the equipment.
The problem is not that the casters are not good, but that the installation method was overlooked during the selection process.
The common installation methods for industrial casters include bottom plate type, screw type, and plug-in type. They are not absolutely superior or inferior, but are suitable for different device structures and usage scenarios.
Why can’t the installation method be chosen randomly?
Casters are the connecting components between equipment and the ground, and the installation method determines how the casters are fixed to the equipment.
If the connection is not secure, it will not only affect the driving experience, but may also cause the device to shake, experience uneven force, and even shorten the service life of the wheels and the device itself.
Therefore, the installation method is not simply a difference in accessories, but an important component of the entire mobile system.
Bottom plate type: widely used in industrial equipment applications
Bottom plate casters are a common installation form in the industrial field.
It is fixed at the bottom of the equipment through installation plates and bolts, with a larger connection area and more uniform force distribution.
Therefore, it is particularly suitable for:
Heavy equipment;
Industrial workbench;
Storage shelves;
Mold transport vehicle;
Automated equipment;
Large tool cabinet.
The characteristic of a large bottom plate is high stability.
When the equipment is subjected to large loads for a long time or requires frequent movement, the bottom plate type usually provides a more reliable connection effect.
However, when replacing the casters, it is necessary to carefully check the size, hole spacing, and aperture of the mounting plate to ensure that it matches the original installation position.
Screw type: easy to install and flexible to adjust
Screw type casters are directly installed into the reserved threaded holes of the equipment through threads.
Compared to the bottom plate type, its installation is simpler and takes up less space.
Therefore, many lightweight devices adopt this approach, such as:
Display equipment;
Lightweight trolley;
Commercial equipment;
Partial medical equipment;
Office and service equipment.
Some screw type products can also be used in conjunction with adjustable feet to achieve fine adjustment of equipment height.
However, it should be noted that during procurement, it is necessary to confirm whether the screw specifications are consistent, including thread diameter, pitch, and length. Otherwise, even if the wheels themselves meet the requirements, installation cannot be completed.
Plug in type: high disassembly efficiency
The plug-in caster mainly relies on the cooperation between the plug-in rod and the internal structure of the equipment for fixation.
Its major advantage is its fast installation and disassembly speed, without the need for complex tools.
Therefore, it is widely used on some devices that require quick replacement or maintenance, such as:
Partial logistics turnover equipment;
Supermarket equipment;
Catering equipment;
Display rack;
Lightweight mobile facilities.
However, the plug-in type is usually more suitable for light or medium light load applications.
If the equipment is subjected to heavy loads for a long time, the connection method should be confirmed based on the actual structure to ensure that it meets the usage requirements.
Why can’t we just look at the wheel diameter when replacing the casters?
When many companies purchase replacement wheels, they only tell the supplier, “I want 150mm wheels
In fact, relying solely on wheel diameter is far from enough.
At least the following parameters need to be confirmed:
Installation method;
Installation height;
Bottom plate size or screw specifications;
Hole spacing and diameter;
Carrying capacity;
Wheel diameter and wheel width.
Any parameter mismatch may affect installation and usage.
Especially the installation method, if chosen incorrectly, it is almost impossible to solve it through simple adjustments in the future.
How to determine which installation method is suitable for your device?
It can be judged from the perspective of device structure.
If there is a reserved installation plate position at the bottom of the device and a high load-bearing capacity is required, a bottom plate is usually more suitable.
If the device itself is designed with threaded mounting holes and you want a more compact installation, you can choose the screw type.
If the device emphasizes quick assembly and disassembly and adopts a dedicated socket structure, a plug-in type can be considered.
It should be noted that the installation method is usually determined by the device structure, not by the casters.
Therefore, before purchasing, it is important to confirm the original installation form of the equipment and then select the corresponding specifications of casters.
A small detail that is easily overlooked
Some users try to modify different installation methods to save procurement costs.
For example, changing the bottom plate type to a screw type, or welding the connectors themselves.
Although this approach can complete the installation in the short term, it may change the original force distribution of the equipment, affecting the connection strength and long-term stability.
For long-term operation or heavy-duty equipment, it is recommended to choose the installation method consistent with the original design, which can ensure installation efficiency and help the equipment operate stably for a long time.
Write it at the end
Industrial casters are not just wheels, but a complete mobile solution.
The wheel diameter determines the capacity, the wheel material affects the usage environment, the load-bearing capacity is related to safety, and the installation method determines whether the casters can truly become a reliable part of the equipment.
Spending a few more minutes confirming the installation method during procurement can often avoid extensive rework and repeat purchases in the future.
Truly professional selection is not just about buying suitable casters, but also about accurately matching every parameter with the equipment.
Is your device using bottom plate, screw type, or plug-in casters? Have you ever encountered the problem of not being able to install casters due to inconsistent installation methods?
