Caster Wheels Under Office Chairs

The caster wheels under office chairs primarily serve to reduce friction and enhance comfort, and they can be maintained through cleaning, lubrication, replacement, and other methods. Details are as follows:

Functions

• Reducing Friction: By converting sliding friction into rolling friction, the caster wheels significantly reduce the resistance when moving the chair, making it easier and less strenuous to move the office chair.
• Enhancing Comfort: Under a constant pressure, the caster wheels increase the contact area between the chair and the ground, thereby reducing the pressure exerted on the human body, making it more comfortable compared to wooden stools.

Cleaning Tips

• Dealing with Hair Entanglement:
  • You can use small scissors to cut the entangled hair one by one, but this is time-consuming.
  • A recommended three-step disassembly cleaning method: First, turn the chair upside down and gently pull out the caster wheel by holding the wheel bracket with your hand (the snap-on design requires no tools; if it is stuck, you can use a screwdriver with a soft cloth to pry it open). After removal, check for hair and debris, use tweezers to pick out long hair from the gaps, then use an old toothbrush dipped in neutral detergent to scrub the surface and bearing gaps, and finally rinse with water (avoid getting water into the bearings). After wiping dry, let it air dry for 10 minutes.
• Cleaning Dirt:
  • Wrap the wheel with a damp facial tissue that has been air-dried (with the textured side facing outwards), secure it with a rubber band, and then sit on the chair and move back and forth. The dirt will transfer to the facial tissue. Repeat the operation until clean, and finally wipe the floor with a cloth.

Maintenance Methods

• Lubrication and Reinstallation: After the caster wheel is dry, drip 1-2 drops of special lubricating oil for office equipment onto the bearing (avoid using cooking oil), and rotate the caster wheel to evenly distribute the lubricating oil. Align the caster wheel with the bracket snap and push it in until you hear a 'click' sound. After confirming that it is firmly installed, turn the chair back upright and test whether the caster wheel moves smoothly. If it is stuck, check for residual debris.
• Daily Maintenance: It is recommended to clean the caster wheels once a month and avoid placing heavy objects on them to prevent bearing deformation and affect usage.

Replacement Method

Turn the chair upside down and pull out the old caster wheel in the opposite direction of the force core (the caster wheel is fixed in the hole with a snap spring). When installing the new caster wheel, insert it forcefully in the direction of the hole.

Tips for Preventing Floor Dirt

Stick invisible tape onto the caster wheels. The width of the tape should be appropriate and the stickiness should be moderate. After tearing it off, there is almost no sticky residue on the wheels. Keep the surface of the tape wrinkled when sticking it to prevent the wheels from being too slippery. This operation is simple and convenient for replacement.
