Office Chair Caster Wheels

Office chair caster wheels come in various types, each with distinct functions, and the choice should be based on actual needs.

1. Wheel Types and Functions

• Locking Wheels: These wheels use a mechanical structure to switch between fixed and mobile states. To lock, push down the locking mechanism (such as a toggle) on the wheel, increasing friction with the ground and preventing the chair from sliding easily. To unlock, push it up to restore mobility. Suitable for scenarios where the chair needs to be temporarily fixed, such as preventing sliding during office work.
• Gravity Wheels: These wheels have a built-in gravity-sensing mechanism. When the chair bears the weight of a person, the resistance to side-to-side rotation of the wheels increases significantly. This design makes the chair more stable during movement, reducing the risk of accidental sliding. Additionally, due to resistance control, movement is quieter, making them suitable for environments requiring silence, such as libraries or late-night office work.
• Fixed Foot Pads: These use a plug-and-pull structure to switch between wheels and fixed foot pads. After removing the original wheels, insert the fixed foot pads to completely immobilize the chair. Suitable for elderly or mobility-impaired users, as well as children's use scenarios, to avoid safety hazards caused by chair sliding.

2. Design and Material Characteristics
Some wheels feature a bearing hollow design, with a hollow center, built-in high-precision bearings, and an outer layer of soft PU material. This design ensures the wheel's load-bearing capacity (as the bearing structure distributes pressure) while reducing friction noise with the ground through the soft PU material. Additionally, the hollow design reduces the overall weight of the wheel, making it easier to move.

3. Size Selection
Wheel size directly affects the chair's mobility and stability. Common sizes are 60mm and 65mm. When choosing, refer to the original wheel size of the chair. Generally, larger wheels (such as 65mm) are more suitable for soft surfaces like carpets, as their larger diameter prevents them from sinking into the fibers. Smaller wheels (such as 60mm) are better for hard surfaces like tiles or wooden floors, offering more flexible movement.

4. Disassembly and Repair Methods
To replace a wheel, insert needle-nose pliers into the gap between the wheel and the chair's footrest, and gently pry to separate the wheel from the axle. When installing a new wheel, align the wheel's axle with the footrest's hole and press firmly until fully embedded. Be careful with the force applied to avoid damaging the footrest or wheel axle.
