Office Chair Bottom Caster Wheels

Here are the cleaning, replacement methods, and price information for office chair bottom caster wheels:

Cleaning Methods:

1. Handling Tangled Hair: If hair is tangled around the caster wheels, carefully use small scissors to cut the hair along the axle direction. Be cautious not to damage the wheel structure. This method is suitable for a small amount of tangled hair but can be time-consuming and requires patience.
2. Cleaning Wheel Dirt: Wet a used facial cloth and let it air dry. Use the textured surface of the cloth to rub against the wheel surface. Then, wrap the wheel with the facial cloth, secure it with a rubber band, and move the chair back and forth to transfer the dirt onto the cloth. Repeat this process 2-3 times for thorough cleaning. This method is eco-friendly and efficient as it does not require chemical cleaners.
3. Preventing Floor Dirt: Stick invisible tape on the wheel surface, choosing tape with a width that matches the wheel and moderate stickiness. Keep the tape surface slightly wrinkled when sticking to reduce wheel slippage and prevent tape residue. Regularly replace the tape to maintain cleaning effectiveness.

Replacement Methods:

1. Removing the Caster Wheels: Turn the chair upside down so that the chair legs face upwards. Observe the caster wheel structure and locate the snap ring position (usually at the connection between the axle and the chair leg).
2. Pulling Out the Caster Wheels: Hold the caster wheel with your hand and apply even force in the opposite direction of the force core (i.e., outward) to pull it out. If the snap ring is tightly stuck, you can slightly rotate the caster wheel to assist in removal. Avoid using excessive force to prevent damage to the chair leg.
3. Installing New Caster Wheels: Align the new caster wheel with the hole on the chair leg and insert it forcefully along the hole direction. Ensure that the snap ring is fully embedded in the hole and securely fastened. After installation, gently shake the caster wheel to test its stability and prevent looseness.

Price Information: The prices of office chair caster wheels vary significantly depending on their type, specifications, and materials. For example:

• Manufacturer-customized 1.4-inch load-bearing casters (snap-ring threaded universal wheels): Approximately ¥1.36 each. Suitable for light-duty office chairs with limited load-bearing capacity.
• Wow-customized 1.5-inch wear-resistant casters (universal wheels): Approximately ¥3.8 each. Made of wear-resistant materials, suitable for frequent movement scenarios with a longer lifespan.
• Wow-customized 2-inch insert-rod flat casters: Approximately ¥3.1 each. The flat design increases the contact area, providing better stability. Suitable for heavy-duty equipment or carpeted floors.

Precautions: Before cleaning or replacing the caster wheels, it is recommended to wear gloves to prevent scratches. If the wheels are stuck, you can spray a small amount of lubricant to assist in removal. When choosing caster wheels, ensure they match the hole diameter of the chair leg to avoid installation failure due to size mismatch.
