No, not all office chairs have the same wheels. In fact, there are a few different types of wheels that are commonly used on office chairs. The most common type of wheel is the caster wheel. These wheels are typically made of hard plastic or metal and have a small ball bearing in the center. Caster wheels roll smoothly and are very durable, making them ideal for use on office chairs.
Another type of wheel that is sometimes used on office chairs is the swivel wheel. Swivel wheels are similar to caster wheels in that they have a small ball bearing in the center, but they also have a locking mechanism that allows them to rotate freely. This makes them ideal for use on chairs that need to be able to move around easily, such as conference room chairs.
Finally, some office chairs have rubber or polyurethane Wheels instead of traditional caster or swivel Wheels. These Wheels provide good traction and are quieter than other types of Wheels, but they can be harder to keep clean.
