Office Chair Seat Casters

The cleaning and replacement methods for office chair seat casters are as follows:

Cleaning Methods

1. Hair Entanglement Handling: If the casters are entangled with hair, there is currently no special tool available. Use extremely fine scissors to carefully cut away the entangled hair. Be patient during the operation to avoid damaging the wheel structure.
2. Dirt Cleaning: First, thoroughly remove the entangled hair. Then, wet a used facial towel and let it air dry. Wrap the wheel with the textured side of the towel and secure it with a rubber band. By repeatedly moving the chair, the friction between the wheel and the towel will gradually transfer the dirt to the towel. Repeat this step several times to complete the cleaning.
3. Preventing Floor Dirt: Stick an appropriately wide and moderately sticky invisible tape onto the wheels. Keep the surface of the tape slightly wrinkled (avoid making it completely flat) when sticking it on to increase friction and prevent the wheels from picking up dirt from the floor due to excessive smoothness. After removing the tape, there will be almost no adhesive residue on the wheels.

Replacement Methods

1. Removing Old Casters: Lay the chair down so that the casters are facing upwards. Hold the caster with your hand and pull it out in the opposite direction of the force core (the metal shaft connecting the wheel to the chair leg). If there is significant resistance, you can slightly rotate the caster to assist in removal.
2. Installing New Casters: After removing the caster, you will see the internal snap ring structure. Align the snap ring with the hole (slot) on the chair leg and insert it firmly in the direction of the hole to ensure that the snap ring is fully embedded in the slot and secured. After installation, gently push the caster to confirm that it is not loose.

Additional Explanation of Office Swivel Chair Structure
The core components of an office swivel chair include the seat cushion, backrest, five-star base, casters (wheels), and pneumatic height adjustment system. Among them, the casters are connected to the five-star base via the force core to enable chair movement; the pneumatic rod is responsible for adjusting the seat height, and the elastic support and rollers work together to complete rotational buffering and movement locking. During daily use, the casters are prone to poor rotation due to the accumulation of hair and dust. Regular cleaning can extend their service life.
