Caster Office Chair Fixation

The fixation of caster office chairs can be achieved through specific caster designs or by replacing fixed accessories. Common methods and accessory information are as follows:

I. Caster Fixation Methods

Some caster office chairs use a snap-ring insertion footpad design for fixation. For example, 2-inch swivel chair fixed casters are directly inserted into the chair legs via a snap-ring structure, combined with anti-slip design to enhance stability. Some models can also be equipped with felt pads to reduce floor friction or protect the floor. This design is typically suitable for temporary fixation or lightweight office scenarios, allowing users to switch between fixation and unlocking by pressing the snap-ring or rotating the caster.

II. Selection and Pricing of Fixed Accessories

If you need to replace fixed accessories, there are various specifications available on the market, with prices varying significantly based on material and function:

• Reinforced solid fixed casters: For example, models produced by Foshan Junyuewei Hardware & Plastic Products Co., Ltd. use solid materials to enhance load-bearing capacity, priced at approximately ¥1.71 to ¥2.0 per unit, supporting dropshipping, 7-day replacement, and 48-hour shipping services.
• Flat plate universal wheels with brake: Available in 1.5-inch or 2-inch sizes from Guangzhou Yujiale Aluminum Co., Ltd., these integrate braking functionality and can be instantly fixed by stepping on them, priced as low as ¥0.95 per unit, also offering fast logistics and after-sales support.
  Users can select accessories based on chair leg size (e.g., 1.5-inch, 2-inch) and functional requirements (anti-slip, braking), ensuring the new caster matches the original chair leg hole diameter during replacement.

III. Installation and Fixation Precautions

1. Installation Steps: The installation process varies for different models of caster office chairs. For example, the P509 model requires inserting five casters into the five-star base sequentially, testing smooth sliding before installing the gas lift; the T37 hollow caster involves connecting the chair legs to the chair body. The installation of fixed casters is generally the same as that of ordinary casters, but the position must be locked with a snap-ring or brake device in the final step.
2. Stability Testing: After installation, check if the fixed casters are in close contact with the ground and ensure there is no significant wobbling when pushing the chair. If using casters with brakes, test the brake sensitivity to ensure fixation effectiveness.
3. Maintenance Recommendations: Regularly clean hair or debris from the casters to prevent jamming; if the fixation structure loosens (e.g., snap-ring deformation), replace the accessories promptly to ensure safety.

By selecting appropriate fixed casters or accessories and following the correct installation process, the fixation needs of caster office chairs can be effectively met.
