Universal Cylinder Replacement

This gas lift cylinder replaces worn pneumatic pistons on swivel office and bar chairs. It fits mechanisms with a 25 mm centre hole and chair bases with a 50 mm outer hole. The chrome finish resists corrosion in daily use.

120 mm Travel Upgrade

Choose this model when the original cylinder has a 120 mm stroke and an extended length of 384 mm. The 1000 lb load rating supports heavy-duty seating without sagging. Verify the draft height of 215 mm matches the old part before ordering.

Heavy-Duty Seat Repair

Suits owners who need a direct swap for a failed lift on a standard five-star base. Not suited for chairs with non-standard mounting diameters or integrated column designs. Buyers who need a different stroke length should select the matching variant.

Questions about this item

What diameter holes must my chair mechanism and base have for this 120 mm travel gas lift?

The mechanism needs a 25 mm hole and the chair base a 50 mm hole for universal fit.

Which step do people skip when installing this pneumatic cylinder?

They forget to measure the old cylinder first; the draft is 384 mm extended, 215 mm compressed, with 120 mm travel.

When should I replace this 500 kg capacity gas lift?

Replace it when the chair sinks under weight, fails to hold height, or the 360-degree swivel becomes stiff or noisy.
