Mini Office Chair Casters

Mini office chair casters are small-sized, multi-functional caster products specifically designed for small furniture. Common sizes range from 1 to 2 inches, with price ranges from 0.29 yuan to 8.78 yuan. The materials are primarily TPR rubber and PP plastic, with some products featuring noise reduction, load-bearing, or braking functions.

Specifications and Suitable Scenarios

Mini office chair casters typically come in sizes of 1 inch, 1.25 inches, 1.5 inches, or 2 inches. Products labeled as 'mini' are mostly used for small furniture or in space-constrained scenarios, such as children's study chairs, mini office chairs, or lightweight mobile devices. Size selection should be based on the furniture's weight and mounting hole spacing. For example, 1-inch casters are suitable for lightweight furniture, while 2-inch casters can bear heavier items.

Material and Functional Characteristics

• TPR Rubber: Offers good elasticity and wear resistance, commonly used in noise-reducing casters to minimize noise during movement, suitable for places requiring a quiet environment.
• PP Plastic: Features high hardness and low cost, mostly used in basic load-bearing casters, suitable for budget-constrained scenarios or where noise reduction is not a priority.
• Functional Enhancements: Some products incorporate braking functions, enabling fixation through foot pedals or manual locking to prevent accidental furniture movement. Load-bearing capacity varies by material and design and should be selected based on furniture weight. For example, a 1-inch PP swivel caster can bear approximately 50 kg, while a 2-inch TPR caster with braking can bear over 100 kg.

Pricing and Typical Products

Market prices vary significantly, with basic 1-inch PP casters priced as low as 0.29 yuan and high-end 2-inch TPR casters with braking and noise reduction priced up to 8.78 yuan. Typical products include:

• The 1-inch load-bearing PP swivel caster from Shenzhen Hongda Furniture Hardware Accessories Co., Ltd., priced at 1.43 yuan, with monthly sales exceeding 13,000 units, suitable for lightweight office chairs.
• The 1-2 inch TPR load-bearing caster with braking and noise reduction from Yangjiang Weibida Caster Manufacturing Co., Ltd., priced at 8.58 yuan, with monthly sales nearing 39,000 units, offering both noise reduction and safety.
• The 1-inch TPR noise-reducing soft rubber roller from Zhongshan Hengshitong Technology Co., Ltd., priced at 0.95 yuan, with monthly sales exceeding 37,000 units, providing excellent cost-effectiveness.

Purchase Recommendations

Before purchasing, ensure that the caster size matches the furniture's mounting hole spacing. Prioritize products with braking functions to enhance safety, and pay attention to the load-bearing parameters and warranty services provided by the merchant (such as a 1-year warranty). For long-term use, TPR rubber casters are recommended to extend lifespan; if budget is limited, PP plastic casters can meet basic needs.
