Generally office chair casters are distinguished in hard floor casters (HFC) and soft floor casters (SFC). Since many different synonyms spook around which leads to misunderstandings the following figure shall bring some light into the darkness of description:
The caster itself consists of two main parts. The core and the sliding surface. While the core is identical the sliding surface differs between HFC and SFC. While the HFC has a soft surface for hard floors like parquet, tiles, laminat or cork the SFC is made of a solid surface for soft floors like carpet. Visually they can be distinguished by the alternating colour of the HFC between the core and the sliding surface.
WHY do hard floors need hard floor casters?
Do you know this scrunching noise when rolling over your floor with your office chair? Using hard floor casters you don't. The soft surface of the wheels compensates unevenness of your floor and therefor reduces the rolling noise.
Contrary to most soft floor casters high quality hard floor casters are manufactured with brakes. That means the brakes release the moment you put weight on them. In other words the chair will not roll away before you sit on it. This reduces the risk of sitting down onto air and prevents accidental shelf bumping with your office chair.
Additionally hard floor casters save your floor from abrasion tremendously. Who doesn't like to put chair mats on his floor, should think about using soft wheels for hard floor. Nasty scratches and light spots from abrasion will appaer within a few weeks.
HOW MUCH will it be for a set of hard floor casters?
"Who buys cheap, buys twice. One time cheap, one time expensive!"

The pressure of price and the resulting low cost manufactured products will lead to low quality in the segment of wheels for office chairs as well. When purchasing hard floor casters you will be on the safe side if the wheels are "made in Germany". Those casters are examined by the independent governmental institution TÜV and therefore fullfill the strict requirements of the renown ISO certificate. This guarantees fewer roll resistence when changing the direction, a long lasting rolling surface made of state-of-the-art material like polyurethan and the casters will meet the DIN Norm EN 12526.
