Teacher Office Chair Casters

The casters used on teachers' office chairs typically belong to the caster components of office swivel chairs, with the core function of supporting chair movement and rotation. Prices vary significantly based on specifications and materials, and replacement requires operation via snap rings. Modern products often feature wear-resistant and quiet designs.

Price Range

The price of office chair casters is significantly influenced by size, material, and functionality. Among common specifications, 1.4-inch load-bearing casters cost approximately ¥1.36 each, suitable for lightweight office scenarios. The price range for 2-inch universal wheels is broader, from ¥0.51 to ¥3.8, with low-end models mostly made of hard plastic and high-end models potentially featuring nylon or metal cores. Quiet universal wheels with brakes, upgraded for additional functionality, cost around ¥4.0 each, ideal for scenarios requiring chair fixation (e.g., when teachers grade assignments). For long-term use on hard floors, it is recommended to choose casters with PU-wrapped edges, which offer superior quiet performance and wear resistance, though prices may increase by 20%-50%.

Replacement Method

Casters are fixed to the chair leg holes via snap rings. The replacement steps are as follows:

1. Preparation Stage: Invert the chair to ensure the chair legs face upward, avoiding scratches on the floor.
2. Removing Old Casters: Use a screwdriver or specialized tool to gently press the snap ring (usually located at the connection between the caster and the chair leg) while pulling out the old caster in the opposite direction.
3. Installing New Casters: Align the axis of the new caster with the hole, insert it vertically, and press firmly until a “click” sound indicates the snap ring is locked.
4. Testing Stability: Return the chair to its upright position and gently push to test whether the caster rotation and braking functions are normal.
   Note: If the snap ring is aged, causing the caster to loosen, replace the snap ring simultaneously or contact after-sales service for repairs.

Industry Background and Design Features

Modern office chair casters generally adopt ergonomic designs, such as:

• Material Optimization: PU (polyurethane) wrapping reduces friction noise with the floor, while nylon cores enhance load-bearing capacity (each caster can bear over 50kg).
• Functional Segmentation: Quiet casters are suitable for libraries or quiet offices, while braking casters meet scenarios requiring temporary fixation (e.g., when teachers fix chair positions during lectures).
• Adaptability: Some high-end models feature thicker wheels or special treads designed for carpets, improving mobility smoothness.

For further purchasing, it is recommended to select specifications based on usage scenarios (hard floors/carpets) and load-bearing requirements (single/double chairs) and prioritize products certified by ISO or national standards to ensure safety.
