Features of Office Chair Wheels

The features of office chair wheels are mainly reflected in aspects such as material, size, load-bearing capacity, interface type, additional functions, and other characteristics, as detailed below:

Material Characteristics: Hard plastic wheels (PP/PU hard wheels) are black in color, hard in texture, smooth on the surface but lack elasticity. When used on hard floors, they can easily trap sand particles, leaving scratches and posing a high risk of floor damage. Soft PU wheels are coated with soft polyurethane on the outer layer, transparent or light gray in color, elastic, roll gently, are less likely to scratch the floor, and offer good noise reduction. Rubber/soft rubber wheels move quietly without leaving black marks, suitable for wooden or tiled floors. Metal materials excel in load-bearing capacity but are prone to scratching the floor and generating significant noise, suitable only for special needs.

Size Characteristics: In terms of diameter, 1.5 - 2-inch wheels are suitable for lightweight office chairs, offering high flexibility; 2.5 - 3-inch wheels are suitable for heavier users or executive chairs, providing strong grip. For office environments, it is recommended to choose wheels with a diameter of ≥60mm, and for long-distance movement, prioritize large-diameter wheels over 75mm. Common interface diameters are 11mm, 12mm, and 15mm. It is necessary to measure the diameter of the old wheel's insert rod or take a photo and consult customer service to avoid interface mismatch.

Load-Bearing Characteristics: Choose wheel load-bearing capacity based on 1.5 - 2 times the actual body weight. For example, when the total weight of a person and chair is 100 kilograms, choose wheels with a load-bearing capacity of ≥150 kilograms to extend service life and avoid deformation.

Interface Type Characteristics: Snap-ring type wheels can be directly inserted and locked with a "click" sound, offering easy installation and wide application. Threaded type wheels require rotation to screw in, have high matching requirements, and need to be confirmed for compatibility with the chair's interface. IKEA-specific wheels are required because IKEA chairs typically use 10mm thin rods, necessitating the purchase of dedicated wheels.

Additional Function Characteristics: Wheels with brake functions are suitable for scenarios requiring fixed positions, such as conference chairs or children's use. Dust cover designs can reduce hair and dust entanglement, lower cleaning frequency, and enhance the user experience.

Other Characteristics: φ60MM PU black wheels are made of polyurethane material. Compared to traditional nylon wheels, they generate lower noise when rolling on hard floors and are less likely to scratch the floor. They also offer certain elastic cushioning to reduce vibration transmission during movement. PU material wheels wear more evenly during long-term rolling and have less friction on wooden or tiled floors.
