Office Chair Anti-Slip Casters
There are several common solutions for anti-slip casters on office chairs:
1. Lockable Function Casters These casters, with a diameter of 60 millimeters, are equipped with a silent sleeve and a soft PU coating layer, achieving a locking function through a mechanical structure. When users need to fix the chair, they simply flip down the locking device on the side of the caster. The operation is simple and offers strong stability. These casters usually come in sets of five and are suitable for scenarios that require frequent switching between mobile and fixed states, such as office or home environments. The soft PU material reduces wear on the floor, while the silent design reduces noise interference during movement.
2. Gravity Casters Gravity casters, also with a diameter of 60 millimeters, achieve an anti-slip effect through an internal mechanical structure. When the chair bears weight, the resistance device inside the caster automatically activates, increasing the frictional force for lateral movement and making it difficult for the chair to slide when under pressure. This design requires no manual operation and is suitable for scenarios that require natural anti-slip properties, such as on carpets or smooth floors. Although the movement resistance is relatively high, the silent characteristic makes it a preferred choice for noise-sensitive environments.
3. Fixed Foot Pads Anti-slip is achieved by replacing the original casters with fixed foot pads. After inserting the foot pads into the bottom of the chair, the contact area between the chair and the floor increases, significantly enhancing the frictional force. This design is suitable for use by children or the elderly. It can prevent the chair from tipping over due to accidental sliding, but it requires complete removal of the foot pads for movement, offering lower flexibility and is more suitable for long-term fixed-use scenarios.
4. Bearing Hollow Casters Bearing hollow casters, with a diameter of 60 millimeters, feature a hollow design with an internal bearing structure, making them relatively heavy and of excellent quality. The outer soft PU coating layer provides cushioning and reduces floor damage. A locking button is provided on the side of the caster, allowing users to fix the caster by flipping the button. The black and gray color scheme is dirt-resistant and versatile, suitable for users who have requirements for both the appearance and stability of the casters.
5. Large-Size Casters Large-size casters with a diameter of 65 millimeters are suitable for chairs with larger original caster sizes. They achieve anti-slip through a side locking device. The white caster body with gray edge design offers better dirt resistance than solid-color casters. These casters are suitable for heavy-duty office chairs that require large-size caster support or for users who have personalized requirements for the appearance of the casters.
Other Options: There are also various types of casters with brakes on the market, such as 2-inch PU silent casters and 3-inch nylon brake casters. Some products combine gravity self-locking or adjustable resistance designs, further enriching the range of anti-slip caster options. Users can make a comprehensive choice based on the chair model, usage scenario, and budget.
