Cross – this is a durable spare part of the chair, to which the wheels of the computer chair are attached and which is the support of the chair itself. It is a design with the rays departing from the center to the periphery, to which the rollers are attached, and the gas lift is fixed in the central part.

  • Strength. Today manufacturers use exclusively high-class durable materials for the manufacture of models. They are resistant to configuration changes, load changes and ensure the integrity of the design for a long time.

  • Standard. One of the features of all the cross is that such nodes are made according to a single technology, which makes it easy to replace the failed design element. Plus, this makes the method of independent removal of the base one for any other similar cross.
  • Fixed Crosses. If the user hinders the big mobility of the chair, it is always possible to replace the wheels on the so-called glider (special shift legs).

Existing models differ in different parameters. Next, consider them a little more.

Dimensions

For classification, three parameters use cross-sizes. Cross diameter. From the middle of the rays can have a diameter of 480 to 700 mm, so it was decided to share these sizes on the target audience of buyers.

  • For children and adolescents. For this category of users, models are developed, which are designed for relatively smaller loads and have a smaller size. The diameter of the crosses for such seats is 480-580 mm.

  • For office and work at the computer (adults). This is the most common model of crosses, the diameter of which ranges in the range of 600-680 mm. Withstands a greater load compared to previous, designed for larger seats.

Subtleties of replacement

To independently replace the cross in its chair, you need to prepare a place of work. The entire surface is worth noting with newspapers or oil. To remove from the chairs on the wheels of the cross, you will need a cross and flat screwdriver, hammer and hands.

  • For better access, turn over the chair with a cross-line up and install it in a steady position.
  • Separate the seat of the chair, reloading the bolts with which it is attached to the PR (item that connects the bottom of the Armchair with Gazlift).
  • Pick up a flat screwdriver, which holds the Gazlift and does not give it to slip out of the hole of the Cross (Located right in the center). In the presence of a casing, you need to bend plastic locks and push it carefully.
  • Remove the pipe from the hole of the crossbar, for this it is easy to tear on it until it comes out.
  • Inside gas-cartridges are small parts and lubricants that can fall out when disassembling. Lubrication can smell the whole room, and small details will be lost – you should not allow it.
  • Pull out the wheels from the old cross, attaching a little effort.
  • Replace the old anticipation of the new and in the reverse sequence, collect the design back.
