Durable Office Chair Casters

If you need durable office chair casters, the following types are recommended:

1. Casters with Locking Function
   These casters have a diameter of 60 millimeters and are designed with a focus on stability and functionality. Their core advantage lies in the inclusion of a silent sleeve, which effectively reduces friction noise between metal components. Additionally, the outer part of the caster is wrapped in soft PU material, which not only protects the floor from scratches but also reduces vibration during movement. The locking mechanism is activated by sideways掰动 (flipping), making it easy to operate. Once locked, the caster makes closer contact with the ground, significantly enhancing stability, making it suitable for office scenarios that require frequent fixing of positions.

2. Gravity Casters
   Gravity casters also have a diameter of 60mm, and their uniqueness lies in their internal mechanism design. When the chair bears weight, the mechanical structure inside the caster automatically increases resistance in the left and right directions, making movement more strenuous and thus preventing accidental sliding. This design enhances stability through physical means while maintaining a certain degree of mobility flexibility, and it operates quietly, making it suitable for environments with high noise reduction requirements.

3. Bearings with Hollow Casters
   This type of caster adopts a hollow bearing structure, with a hollow design in the middle and high-precision bearings embedded inside. This not only ensures the texture of the caster but also enhances overall stability by increasing weight. The exterior is also wrapped in soft PU material, providing floor protection and available in black and gray color options. Its locking mechanism is similar to that of casters with a locking function, activated by sideways掰动 (flipping), and once locked, stability is significantly enhanced, making it suitable for scenarios that require both mobility and fixation.

4. 65mm Specification Casters
   If the original office chair casters are larger in size (e.g., 65mm), you can choose replacement casters of the same specification. These casters usually come with a side locking function, and the operation method is the same as the aforementioned types. They are available in white and black color options, with the white casters featuring a gray edge design, combining aesthetics with dirt resistance, making them suitable for office environments with high appearance requirements.

5. Swivel Casters with Brakes
   Some swivel casters achieve locking functionality through single-brake or dual-brake mechanisms, allowing users to quickly fix the casters by stepping or hand-controlling to prevent chair sliding. In terms of material, polyurethane casters are the preferred choice for mid-to-high-end office chairs. They combine wear resistance, noise reduction, and floor protection characteristics, and are less likely to deform or be damaged during long-term use, making them suitable for office scenarios with high-frequency movement.
