Universal office chair cylinder

The BFKK gas lift cylinder replaces the pneumatic piston on most office, salon, executive and rolling-stool chairs. It supports up to 1000Lbs, exceeding typical replacement cylinders, and carries SGS and BIFMA certifications for safety and explosion-proof construction. The thickened outer steel body provides durable, stable operation with silent 360° rotation.

Adjustable 5.5 inch travel

Fully compressed height is 11.4 inches and fully expanded height is 16.9 inches, giving 5.5 inches of vertical adjustment. This travel is higher than many standard cylinders, so buyers should measure their existing unit before ordering to ensure the range matches their desk and seating preferences.

1000Lb load rating decides fit

The single specification that determines suitability is the 1000Lb maximum weight capacity. Chairs or users exceeding this limit need a heavier-duty cylinder, while lighter-duty replacements will not match the durability or certified safety of this model.
