Office Chair Special Casters
There are various types of office chair special casters, and their prices vary depending on functions, materials, and specifications. Common types include fixed casters, swivel casters, casters with locking functions, and gravity casters, etc.
Basic fixed casters are mainly economical and practical. For example, the 2-inch fixed casters for swivel chairs feature a snap-ring inserted footpad design. A non-slip felt pad can be added at the bottom to reduce wear on the floor, and the price is approximately ยฅ1.71. The reinforced solid fixed casters for swivel chairs also use a snap-ring structure, but the wheel body material is more robust, enhancing the load-bearing capacity, with a price of about ยฅ2.0. These casters are suitable for scenarios where the chair needs to be fixed in place for a long time, such as in front of a desk or beside a conference table.
Swivel casters emphasize flexibility. For example, the 1.5-inch/2-inch flat-plate swivel casters support 360-degree rotation. Some models are equipped with a braking function, allowing the chair's position to be fixed by stepping on or flipping a switch, with a price of about ยฅ0.95. These casters are suitable for scenarios where the chair needs to be moved frequently, such as in open office areas or family activity spaces.
Special-function casters are designed for specific needs. For example, the 60-millimeter-diameter wheels with locking functions are wrapped with soft PU silent sleeves on the outside, generating low noise during movement. To lock them, simplyๆฐไธ (this Chinese verb may need a more natural English equivalent like 'flip down' or 'press down' depending on the actual mechanism; here we use 'flip down' for illustration) the wheels, and a set of five provides stable support. Gravity casters achieve 'dynamic fixing' through an internal mechanical structureโwhen the chair is under pressure, the lateral resistance of the wheels increases, requiring a bit more effort to move, but offering significant noise reduction, suitable for noise-sensitive environments.
Fixed footpads are another option. By pulling out the original casters and inserting the footpads, the chair can be completely fixed, avoiding the risk of sliding. This is especially suitable for families with children or the elderly, or scenarios where the chair needs to remain absolutely still.
When selecting, it is necessary to comprehensively consider the usage scenario, floor material, and budget: For hard floors (such as tiles and wooden floors), it is recommended to choose casters with felt pads or silent sleeves to reduce scratches; for scenarios requiring frequent movement, swivel casters are the priority; for noise-sensitive scenarios or those requiring temporary fixing, gravity casters or casters with locking functions can be considered; fixed footpads are suitable for scenarios where no movement is required at all.
