CUSTOMIZED SOLUTIONS
In modern furniture design, casters have become an indispensable accessory. Whether it's an office chair, warehouse shelving, or a hospital cart, casters not only provide mobility but also contribute to the durability and safety of the furniture. However, many businesses and individuals often neglect caster maintenance during use, resulting in a shortened service life and frequent damage. This article will analyze furniture caster maintenance methods from multiple professional perspectives and provide detailed technical guidance to help users extend their caster life. Information about caster suppliers will also be included for wholesale customers.
Before performing maintenance, it's important to have a thorough understanding of casters. There are many different types of casters, and each requires slightly different maintenance methods.
Furniture casters can be categorized into the following categories based on their structure:
| Caster Types | Features | Applicable Scenarios | Advantages |
| Fixed Casters | Can only roll forward and backward | Shelves and cabinets | Simple structure, low cost |
| Swivel Casters | Can rotate 360° | Office chairs and mobile carts | High flexibility and easy operation |
| Twin Casters | Two parallel wheels | Industrial handling | High load-bearing capacity and good stability |
| Brake Casters | With a brake mechanism | Medical equipment and laboratories | High safety and anti-slip mobility |
The material of the caster determines its wear resistance and applicable environment:
Polyurethane (PU) wheels: Wear-resistant and noise-reducing, suitable for wooden and tiled floors.
Rubber wheels: Good elasticity and strong shock absorption, but prone to wear.
Nylon wheels: High hardness and strong load-bearing capacity, suitable for industrial warehouse environments.
Metal wheels: High load-bearing capacity and high-temperature resistance, but prone to scratching.
Different caster materials require different lubricants and cleaning methods for maintenance, which is also key to extending their service life.
Proper daily maintenance can significantly extend the life of your casters and reduce accidental damage.
When a caster is rolling, dust, hair, and fibers can easily become entangled in the axle or swivel mechanism. Weekly or bi-weekly cleaning is recommended:
Use a dry cloth or soft-bristled brush to remove any debris from the wheel surface and axle.
For difficult-to-remove swivel casters, use compressed air to blow away dust.
Lubrication reduces friction and prevents premature axle wear. Common lubrication methods are as follows:
Oil-based lubricants: Suitable for metal axles and load-bearing casters, but they tend to attract dust.
Silicone grease: Suitable for plastic and PU casters, it is heat-resistant and provides excellent friction reduction.
| Wheel Material | Recommended Lubrication Method | Lubrication Frequency | Precautions |
| PU Wheels | Silicone Grease | Once a Month | Avoid using solvent-containing oil to prevent wheel tread degradation |
| Nylon Wheels | Motor Oil/Lithium-Based Grease | Every Two Weeks | Clean the Axle before Lubricating |
| Rubber Wheels | Dry Powder Lubricant | Once a Month | Prevent grease from contaminating the floor |
| Metal Wheels | Machine Oil | Once a Month | Avoid excessive oil dripping; Maintain rust prevention |
Furniture casters may loosen their screws and nuts over extended use. Quarterly inspections are recommended:
Confirm that the axle nuts are tightened.
Check the connection between the base plate and the furniture for looseness.
Appropriately reinforce any loose areas to prevent wheels from falling off and causing accidents.
Maintenance strategies vary depending on the environment in which furniture casters are used.
Office floors are often wood or carpeted:
Avoid direct contact between hard metal wheels and the floor; opt for PU or rubber wheels.
For furniture that is not moved for extended periods, move it monthly to prevent fixed wheel marks. Avoid excessive wheel dust and reduce axle jamming.
Warehouses and factories often have concrete or metal floors:
Choose nylon or metal wheels with high load-bearing capacity and strong wear resistance.
Lubricate the axles regularly to prevent dust and metal shavings from damaging the bearings.
Perform a functional test on the brake wheels to ensure safe operation.
Hospitals and laboratories have high hygiene requirements for casters:
Prefer easy-to-clean, corrosion-resistant materials (such as stainless steel wheel frames with polyurethane wheels) are preferred.
Wipe the wheel surface with disinfectant after each use to prevent bacterial growth.
Regularly check the brake mechanism and universal wheel flexibility to ensure safe movement.
Even after maintenance, casters may still experience problems with long-term use.
Cause: Dust, entangled fibers, insufficient lubrication
Solution:
Remove the wheel and clean the axle and universal joint.
Apply a suitable lubricant to the axle. Test for smooth rotation and reinstall.
Causes: Excessive load, rough floor, and prolonged use
Solution:
Replace worn wheels; wear-resistant PU or nylon wheels are recommended.
Adjust the furniture load to avoid overloading.
Cause: Loose screws or worn threads
Solution:
Check and tighten all screws.
For severely worn threads, apply thread locker or replace the screws.
| Problem Type | Common Causes | Maintenance Recommendations |
| Wheel sticking | Dust or fiber entanglement | Clean and lubricate the axle |
| Worn Elastic Wheel | Overload or friction | Replace the wheel and control the load |
| Caster Falls Off | Loose screws | Tighten the screws or replace the threads |
| Excessive noise | Axle wear or lack of oil | Lubricate or replace the axle |
In addition to maintenance, choosing high-quality casters and a reliable caster supplier is equally important.
Load Capacity: Choose casters with an appropriate load capacity based on the weight of the furniture.
Surface Material Compatibility: PU or nylon wheels are recommended for hard surfaces, while rubber wheels are an option for soft surfaces.
Braking Function: Choose casters with brakes for furniture that needs to be fixed in place.
Durability: High-quality bearings and a sturdy wheel frame extend the service life.
