Flat-Shaped Casters for Office Chairs

The common types and selection suggestions for flat-shaped casters for office chairs are as follows:

Currently, there are relatively few direct descriptions of “flat-shaped casters” for office chairs in the market, but some product information may involve similar designs. For example, the “flat-plate casters” or “snap-on wheels” launched by some merchants may conform to the characteristics of a flat structure. These casters usually adopt a flat design. Compared with traditional round wheels, they have a larger contact area with the ground, making them more suitable for use on soft floors (such as carpets), reducing the risk of sinking while maintaining a certain degree of mobility flexibility.

Common Types and Price References

1. Insert-Rod Flat-Plate Casters
   For example, the “Wow Custom Insert-Rod Flat-Plate Caster” has a size of 2 inches and supports customization of materials and colors. It is suitable for home or office settings. Its price is approximately ¥3.1 per piece. These casters are usually connected to the chair legs via insert rods, making installation convenient and suitable for scenarios that require frequent replacement or adjustment.

2. Snap-On Universal Wheels
   For example, the “Universal Wheel Snap-Spring Caster” is available in two sizes: 1.5 inches and 2 inches. It adopts a snap-on design and can be directly fixed to the chair legs. Its price is approximately ¥3.6 per piece. The flat structure of these casters may be achieved by optimizing the shape of the wheel body, making them suitable for office environments with high stability requirements.

Selection Suggestions

• Confirm Specification Compatibility: The size of the flat-shaped caster (such as wheel diameter and insert-rod diameter) needs to be compatible with the chair legs to avoid installation difficulties or looseness.
• Material and Load-Bearing Capacity: Prioritize nylon or polyurethane materials, which are highly wear-resistant and can reduce scratches on the floor. If the office chair is relatively heavy, confirm whether the load-bearing capacity of the caster meets the standard.
• Floor Adaptability: If the office area is carpeted, flat-shaped casters may be easier to push than round wheels due to their larger contact area. For hard floors (such as tiles and wooden floors), the difference between the two is relatively small, and models with good sound insulation can be prioritized.

Precautions
Since “flat-shaped caster” is not a universal term in the industry, some merchants may use names such as “flat-plate caster” or “snap-on wheel” to describe similar products. It is recommended to directly contact the supplier and request side views or 3D models of the wheels to confirm whether they have a flat design. In addition, before purchasing, you can request sample testing to ensure that the smoothness of movement and noise level of the casters meet expectations.
