Office Chair Base Specifications
The specifications of an office chair base are typically defined by parameters such as diameter, load-bearing capacity, caster sleeve size, and central hole size. Here is a detailed explanation:

Base Diameter: The standard range for the diameter of an office chair base is usually between 24 and 28 inches (approximately 61 to 71.1 centimeters). This size range meets the needs of most office environments, ensuring stability during use without occupying excessive space. For example, in a regular office setting, a 24-inch base diameter provides sufficient support area, keeping the chair stable whether moving or stationary; in situations requiring higher stability, such as large conference rooms or executive offices, a 28-inch base diameter is more appropriate.
Load-Bearing Capacity: Load-bearing capacity is one of the key indicators for evaluating the performance of an office chair base. Different models of office chair bases have varying load-bearing capacities. For instance, the PAH-H350 model office chair base can support up to 1136 kilograms. This means it can handle heavier weights, making it suitable for individuals with larger builds or those who need to sit for extended periods. A higher load-bearing capacity ensures that the chair will not be damaged by excessive weight during use, extending its lifespan.
Caster Sleeve Size: The caster sleeve size is also an important parameter in the specifications of an office chair base. Taking the PAH-H350 model as an example, its caster sleeve measures 11*22mm. The size of the caster sleeve affects the installation and stability of the casters. An appropriate size ensures a firm connection between the casters and the base, allowing the chair to move more smoothly and reducing noise and wobbling.
Central Hole Size: The central hole size is typically used for installing the chair's gas lift or other height-adjustment mechanisms. The PAH-H350 model has a central hole of 50mm, which must match the corresponding gas lift or other height-adjustment device to ensure the chair can be raised and lowered normally and adjusted in height. An appropriate central hole size guarantees the stability and safety of the chair during use, preventing malfunctions or safety hazards caused by mismatched sizes.
