Special Wheels for Office Chairs

Information on the types, functions, materials, sizes, and prices of special wheels (casters) for office chairs is as follows:

Types and Functions

1. Lockable Wheels: These can be locked and unlocked by flipping a button, suitable for scenarios where the chair needs to be fixed, such as maintaining stability during office work or preventing the chair from sliding and interfering with others.
2. Gravity Wheels: These increase lateral resistance under the influence of gravity, making movement more strenuous but quieter, suitable for environments with high noise-reduction requirements, such as libraries, bedrooms, or late-night office settings.
3. Fixed Foot Pads: These can replace traditional wheels to keep the chair completely stationary, suitable for scenarios involving the elderly, children, or those requiring a long-term stable sitting posture, preventing accidents caused by wheel sliding.

Materials and Characteristics

1. Rubber Wheels: These offer good elasticity and wear resistance, suitable for hard floors (such as tiles and wooden floors), but may produce slight noise due to friction after long-term use.
2. Nylon Wheels: These have high hardness and strong load-bearing capacity, suitable for soft floors like carpets, but may produce significant noise during movement.
3. Polyurethane (PU) Wheels: These combine the advantages of rubber and nylon, offering good noise reduction and wear resistance. Some products are wrapped with soft PU on the outer layer, further reducing noise and protecting the floor, suitable for various floor types.
4. Noise-Reduction Sleeve Design: Some wheels are equipped with additional noise-reduction sleeves (such as rubber or silicone materials), significantly reducing friction sounds during movement, suitable for noise-sensitive environments.

Size Specifications

Common sizes include 60mm, 65mm, 1.25 inches, 1.5 inches, and 2 inches, etc. Selection should be based on the chair model and floor type:

• Small Sizes (e.g., 60mm): Suitable for lightweight chairs or narrow spaces, offering more flexible movement.
• Large Sizes (e.g., 2 inches): Offer stronger load-bearing capacity, suitable for heavy-duty chairs or uneven floors, but with slightly lower flexibility.

Price and After-Sales Service

Prices vary significantly based on brand, material, and function:

• Basic Models: Ordinary rubber or nylon wheels, priced as low as 1.61 yuan per piece, suitable for those with limited budgets or temporary use.
• Mid-to-High-End Models: Polyurethane (PU) wheels or those with noise-reduction and locking functions, priced from tens to hundreds of yuan, suitable for long-term use or users with high experience requirements.
• After-Sales Service: Some brands offer guarantees such as 7-day replacement and 48-hour shipping. Before purchasing, confirm the after-sales policy to reduce risks.

When selecting, comprehensively consider the usage scenario, floor type, budget, and functional requirements, prioritizing products with durable materials, matching sizes, and comprehensive after-sales service.
