Office Chair Casters

Office chair casters are the core components for mobility and support in office chairs, directly affecting user experience and safety.

Functions and Testing

Office chair casters must meet core requirements such as wear resistance, smoothness, and stability. The life test machine is a key inspection device that simulates both obstructed (e.g., carpet seams, small stones) and unobstructed (e.g., smooth floors) scenarios, testing the casters' wear, stuttering frequency, and risk of detachment through continuous sliding. For example, in obstructed testing, casters must withstand repeated impacts without breaking; in unobstructed testing, they must maintain low noise and flexible steering. Such tests comply with international office chair testing standards (e.g., BIFMA or GB/T standards) to ensure product durability.

Product Types

Based on material and design, casters can be classified into the following types:

• Transparent Wheel Casters: Made of high-strength polycarbonate or acrylic, these casters feature a transparent appearance that combines aesthetics with practicality, commonly used in modern minimalist office chairs, though their wear resistance is slightly lower than metal wheels.
• Reinforced Solid-Core Fixed Casters for Swivel Chairs: Made of solid rubber or nylon with no rolling mechanism, these casters are suitable for scenarios requiring fixed positions (e.g., beside conference tables) to prevent accidental movement.
• 2-Inch Universal Transparent Crystal PU Spring Clip Casters: Combining PU (polyurethane) coating with a metal spring clip structure, these casters have a diameter of 2 inches (about 5 cm), balancing quiet operation and load-bearing capacity, suitable for carpets or hard floors.
• 2-Inch Threaded Spring Clip PU Silent Furniture Casters: Featuring a threaded installation design to simplify assembly, these casters use PU material to reduce sliding noise, suitable for home or open-plan offices.
