Office Chair Caster Installation

Admin October 19, 2026

The steps for installing casters on office chairs vary depending on the model, and operations should be carried out according to the specific model. Here are the installation methods for common models:

Q295 Caster Model:

  1. Install Casters: Insert the five casters one by one into the corresponding holes on the five-star base, ensuring that the casters are fully embedded and free of looseness.
  2. Install Gas Cylinder: Insert the thick end of the gas cylinder (usually with a metal head) into the central hole of the five-star base and gently press it until it is fully secured.
  3. Subsequent Assembly: Complete the installation of other components (such as the seat cushion and backrest) according to the instructions. Usually, the other end of the gas cylinder needs to be inserted into the hole at the bottom of the seat cushion.

P509 Model:

  1. Install Casters: Install the five casters one by one into the holes on the five-star base. After installation, test the smoothness of the casters by moving them to ensure there is no jamming or abnormal noise.
  2. Install Gas Cylinder: Insert the gas cylinder into the central hole of the five-star base, ensuring that the gas cylinder is perpendicular to the five-star base and firmly connected.
  3. Complete Assembly: Install the gas cylinder protective sleeve, seat cushion (align it with the hole at the top of the gas cylinder), backrest, and other components in sequence. Finally, check that all connections are secure.

  1. Install Casters: Align the casters with the holes on the five-star base and press them firmly until they are fully embedded, ensuring that the casters are oriented in the same direction.
  2. Install Gas Cylinder: Insert the gas cylinder into the central hole of the five-star base. For some models, rotate the gas cylinder to secure it.
  3. Assemble Seat Cushion: Align the hole at the bottom of the seat cushion with the top of the gas cylinder and gently press it down until the buckle is locked.
  4. Install Backrest: Depending on the design, the backrest may be connected to the seat cushion with screws or buckles. Align the holes and secure them.

Precautions:

  • Before installation, check that the casters, gas cylinder, and other components are intact to avoid using damaged parts.
  • Keep the five-star base level during installation to prevent uneven force on the casters, which could lead to installation failure.
  • If the gas cylinder is difficult to insert, slightly rotate it to adjust the angle. Do not force it in.
  • After installation, test the chair's lifting, rotation, and caster movement functions to ensure there are no abnormalities before use.

The installation steps for different models may vary slightly due to design differences. It is recommended to refer to the product manual first or contact after-sales service for precise guidance.
