Replacement Cylinder for Tall Seating
This WORKPRO gas lift cylinder replaces failed pneumatic pistons in drafting chairs, bar stools and salon stools. It supports a 1000 pound lifting and pull capacity and meets SGS certification under ANSI/BIFMA X5.1 and EN 1335 standards. The 8 inch stroke extends the seat height range from 13.5 to 21.5 inches, reaching a final height of 22 to 28 inches for standing desks.
Upgrade from Worn or Short-Stroke Units
The cylinder is worth fitting when an existing lift sinks, leaks or no longer reaches the required working height. Its 1.1 inch top taper and 2 inch bottom taper match the universal standard used in most task and drafting seats. Builders who need a longer stroke than the original equipment provided will gain the extra 8 inches of travel without changing the chair base.
Fits Standard Seat Mechanisms and Bases
Installation requires only a hammer or Allen wrench to remove the old unit and press the new cylinder into the 1.1 inch seat-plate hole and 2 inch centre-hole base. The 1.57 inch outer diameter at the bottom ensures compatibility with standard five-star bases. Buyers who need a non-standard taper or a shorter stroke for low-profile seating should verify dimensions before ordering.
