Changing roles at an office chair

The majority of roles on which an office chair slides are attached using a relatively simple insertion technique. Threaded fittings may be present on some older or luxury models. When changing the appropriate selection of the new set of rollers makes more work than the replacement itself.

In case of malfunction, first clean

The cross-leg of an office chair has four or five outriggers with the rollers attached to their ends. If the roll quality or mobility is limited, always try to clean the rollers first.

In particular, hair likes to get caught on the axles of the rollers and block them. Helpful are a normal household scissors with pointed blade ends, a long-handled tweezers and a vacuum cleaner. The "rolled-up" hairs are pulled out and separated into individual pieces again and again.

Common plug connections

In order to repair the rolling function of an office chair, it is not necessary to disassemble the chair. A lateral lying down of the chair is sufficient to get to the rollers.

Clamping and plug connections of the roller bars are stored in simple wire springs. An annular recess on the upper side of the spar lets the springs "lock in place". Bolted variants have a standing thread instead of the spar with a taper. It is screwed into the existing hole with internal thread in the respective boom.

Replace mated rollers

  • Lay the chair sideways on a firm surface.
  • Grasp the entire roll body with one hand and pull the roll out of its storage. You have to "overcome" the force of the spring wire. If necessary, a carefully applied pry tool can assist.

Replace bolted rollers

You need two matching wrenches or a wrench and pliers. The two counter-rotating nuts are located above the roller on the spar. The threaded connection in the chair foot turns counterclockwise. Accordingly, the locknuts are screwed.

Choose correct roles

When choosing the correct or improving new roles, the rule of thumb is that the role should have the opposite property of the soil. For soft surfaces such as carpet or nonwovens, hard rolls are ideal, for hard floors such as laminate, parquet and stone softer roles are better.

Tips & Tricks

Both soft and hard wheels can be selected with sound-insulating tread pads. Always replace the complete set of rollers.
