Office Chair Casters
Office chair casters typically refer to the wheels used at the bottom of office chairs. Common types include silent swivel casters and other functional casters, which are characterized by silence, wear resistance, and load-bearing capacity, suitable for furniture mobility needs. Here are the specific classifications and characteristics:
Silent swivel casters are the mainstream type of office chair casters, with their core function being to reduce movement noise by optimizing wheel material and structural design. For example, the 1.5/2/3/4-inch industrial brake-equipped swivel casters sold directly by Taiyada use PU (polyurethane) or TPE (thermoplastic elastomer) materials. These materials have high elasticity and low friction coefficients, effectively absorbing vibrations and reducing friction sounds with the ground. The 2-inch transparent wheel office chair swivel casters fix the wheel body with a snap ring structure, ensuring no direct metal collision between the wheel axle and the bracket during rotation, further reducing noise. The steering design of swivel casters usually adopts a double-bearing structure, allowing the wheels to rotate freely 360 degrees, enhancing movement flexibility.
Other types of casters optimize functions for specific usage scenarios. The 1-inch to 2-inch TP flat-bottomed swivel brake casters improve stability by reducing the wheel diameter, suitable for scenarios requiring frequent starts and stops, such as conference chairs or training chairs. Medium-sized TPR (thermoplastic rubber) silent casters increase load-bearing capacity by thickening and widening the wheel body, capable of bearing over 50 kilograms, suitable for heavy-duty office chairs or flatbed carts. The "silent double-bearing brake-equipped heavy-duty diamond casters" among furniture swivel casters use metal brackets and thickened wheel bodies, with a load-bearing capacity of over 100 kilograms. The brake device fixes the wheel body through friction plates, ensuring the stability of the chair when stationary.
Material selection directly affects caster performance. PU wheels have better wear resistance than ordinary rubber, suitable for wooden floors or tiled floors; TPE wheels have better elasticity, suitable for soft floors such as carpets; TPR wheels combine the wear resistance of rubber with the processability of plastics, with lower costs. The brake function is achieved through foot pedal or manual operation, with some high-end models adopting automatic brake design, automatically locking the wheel body when the chair is stationary for more than 3 seconds.
When purchasing, it is necessary to match parameters according to the usage scenario. For home office chairs, it is recommended to choose 2-inch PU silent swivel casters, balancing silence and load-bearing capacity; for conference rooms or training rooms, 1.5-inch TP wheels with brakes can be selected for easy positioning; for heavy-duty office chairs, metal bracket casters with a load-bearing capacity of over 80 kilograms should be chosen to ensure no deformation during long-term use.
