Casters are increasingly common in modern furniture design and use. Whether it's an office chair, storage cabinet, display stand, or home organizer, properly installing casters not only improves furniture mobility but also extends the lifespan of both the casters and the furniture itself. However, many users often encounter problems during installation, such as insufficient load-bearing capacity, unstable installation, or poor sliding. This article, drawing on the experience of a professional caster supplier, will detail how to properly install furniture casters, helping you avoid common pitfalls.
To purchase or wholesale high-quality furniture casters, please contact Giessen Caster Supplier (email: Giessencasters@gmail.com, website: https://www.giessencasters.com).
Before installing casters, it's important to clarify the following:
Furniture usage: Is it for daily home use or commercial use?
Load capacity: Will it need to carry heavy objects?
Frequency of movement: Is it occasional or frequent?
Use environment: Is the flooring wood, tile, or carpeted?
These factors will directly influence the type of caster you choose, as well as the differences in installation methods.
To facilitate selection, the following lists several common furniture caster categories:
| Caster Type | Features | Suitable Scenario |
| Fixed casters | Only move in a straight line | Furniture that needs to maintain its orientation, such as sliding bookcases |
| Swivel casters | Rotate 360° | Furniture that needs to be flexible and movable, such as office chairs and storage shelves |
| Casters with brakes | Lockable at any time | Furniture that needs to be both movable and fixed, such as display cabinets |
| Silent casters | Low noise | Suitable for bedroom furniture, hospital wards |
| Rubber casters | Shock-resistant and wear-resistant | Suitable for tile and wooden floors |
The following tools are required to properly install casters:
Electric drill or screwdriver
Ruler or tape measure
Level
Screws and expansion nuts (depending on the installation method)
Anti-slip pads or fixing plates (for increased load-bearing capacity)
The design of the furniture and casters determines the installation method. Common methods include the following:
Baseplate Screw-On Installation:
Drill a hole directly into the bottom of the furniture and secure the caster base with screws.
Advantages: Stable and suitable for most furniture.
Disadvantages: Requires certain tools.
Pole-On Installation:
The caster comes with a metal rod that inserts into a pre-cut hole in the bottom of the furniture.
Advantages: Simple installation.
Disadvantages: Limited load-bearing capacity, suitable for lightweight furniture.
Expansion Sleeve Installation:
Drill a hole in the bottom of the furniture, insert the expansion sleeve, and then insert the caster.
Advantages: Suitable for metal furniture or furniture requiring additional stability.
Disadvantages: Complex operation.
Welding Installation:
Applicable to metal-frame furniture, the casters are secured by welding.
Advantages: Extremely strong load-bearing capacity.
Disadvantages: Requires specialized welding equipment and techniques.
Step 1: Measure the base of the furniture to determine the caster mounting points. Ensure that all four casters are spaced evenly to prevent tilting.
Step 2: Use an electric drill to drill holes in the base of the furniture, matching the hole diameter to the screw diameter.
Step 3: Place the caster base in the hole and secure with the screws. Tighten the screws thoroughly to prevent loosening.
Step 4: Check that the casters rotate freely, taking care to avoid scratching the base of the furniture.
Step 5: Place the furniture and perform a load test to ensure that all four wheels are evenly loaded.
It is recommended to use casters with a thickened steel base for greater stability.
When installing on wooden furniture, place a metal shim first to prevent cracking in the wood.
When installing in bulk, it is best to use screws and accessories recommended by a professional caster supplier to ensure consistency.
Cause: Mounting holes are not aligned.
Solution: Use a level to adjust the position and add shims if necessary.
Cause: Screws are overtightened or the base plate is rubbing against the furniture.
Solution: Loosen the screws appropriately and add shims to the contact surface.
Cause: Lightweight casters are used that cannot meet the required weight of the furniture.
Solution: Replace with heavy-duty furniture casters. It is recommended to consult the caster supplier for load-bearing specifications in advance.
Cause: Hard nylon casters are scratching wooden floors or tiles.
Solution: Replace with rubber or PU casters.

As a long-time supplier of Giessen casters, we recommend:
For mass production, furniture manufacturers should include caster mounting locations during the design phase. Screws and accessories from different batches must be of the same specifications to avoid component variations that could affect installation quality.
For high-end furniture, we recommend using silent, scratch-resistant casters to enhance the user experience.
Regularly check casters for looseness and tighten or replace if necessary.
