These castors fit very many office chairs. The decisive factor is the diameter of the pin (metal part which is inserted into the frame of the office chair). You need to measure this for your current castors. With the castors offered here, the pin has a diameter of 10mm.
The pin length is usually the less necessary information, the height of the snap ring and the diameter of the pin is the more decisive factor. What do you want the information for?
Hello Leosomemore. Since Ikea unfortunately does not give any information about the pin diameter, you would have to take a castor off and measure the pin diameter yourself. If this is also 10 mm, as with the Topstar castors, then they should fit (emphasis on should).
If I were you, I would ask the Ikea customer service to be on the safe side. They are quite helpful and competent.
On the other hand, you also have a right of return at Galaxus and could therefore also return the castors if they don't fit. :)
Kind regards
Do these castors only fit Topstar chairs? I need to replace the castors from a Girsberger chair: 5 hard floor castors pin 20mm length /10mm diameter, wheel diameter 50mm. The pin would actually fit, but when I compare the snap ring, the one on the Girsberger is probably further down (5mm from the top edge, looks like the Amstyle castors, but 10 instead of 11mm). If the Topstar castors don't fit, what else does Digitec have on offer for my specifications? I can only find Topstar castors and Amstyle.
