Hollowed-Out Office Chair Casters

The installation methods for casters of different models of hollowed-out office chairs vary and need to be operated according to the specific model. Some universal caster wheels can be adapted and replaced.

I. Installation Methods for Casters of Common Models

1. w929 Hollowed-Out Model - Non-sliding Seat

   • When installing, turn the bottom of the five-star base upwards to ensure the correct insertion direction of the casters.
   • Insert the five casters one by one into the reserved holes on the five-star base. Make sure each caster is fully embedded to avoid looseness.
   • When inserting the gas cylinder, align the thicker end of the gas cylinder with the center hole of the five-star base and gently press it until it is completely fixed.

2. W209 Hollowed-Out Computer Chair

   • The installation steps are similar to those of the w929 model. Also, turn the bottom of the five-star base upwards.
   • Insert the five casters one by one into the holes on the five-star base, ensuring a tight fit between the casters and the holes.
   • When inserting the gas cylinder, keep the gas cylinder vertical. Insert the thicker end into the center hole of the five-star base and press it gently to fix it.

3. T37 Hollowed-Out Computer Chair

   • The reference information does not provide detailed installation instructions for the casters, but usually, the chair legs and gas cylinder need to be installed first, and then the casters are fixed through the structure of the chair legs.
   • It is recommended to contact the manufacturer for specific installation drawings or video instructions to avoid damaging the components due to improper operation.

II. Adaptation and Replacement of Universal Caster Wheels

1. Available Models on the Market

   • Cross-border Export Insert-rod 3-inch Transparent Universal Double Wheels: Priced at 8.5 yuan, suitable for most gaming chairs and office chairs. The insert-rod design allows for quick installation.
   • Amazon Cross-border 2.5-inch Flower-core PU Double-sheet Silent Universal Caster Wheels: Priced at 9.5 yuan, the PU material provides good sound insulation, and the flower-core structure enhances the load-bearing capacity.

2. Replacement Precautions

   • Confirm that the size of the original caster (such as diameter and insert-rod thickness) is the same as that of the new wheel to avoid installation failure due to size mismatch.
   • Some casters need to be fixed with special clips or screws. Check whether the new wheel includes the accessories before replacement.
   • Keep the chair legs clean during installation to avoid debris affecting the rotation flexibility of the casters.

III. General Installation Suggestions

1. Read the product manual carefully before installation, especially the instructions on the connection method between the casters and the chair legs.
2. If the casters wobble after installation, check whether the holes are aligned or use rubber gaskets to adjust the gap.
3. Regularly check the wear condition of the casters. If there is stuttering or abnormal noise, replace them in a timely manner to avoid safety hazards.
