Office Chair Cylinder Replacement, TSR Gas Cylinder Class 4 TUV, Heavy Duty Gas Lift Piston, 4.4" Stroke, Compatible with Partial Models of Herman Miller, Steelcase, Haworth etc


  • Our CLASS 4 gas spring uses a piston rod made of high-quality steel with a wall thickness of 2.5mm, which has undergone multiple grinding, nitriding, and other QPQ thermal processing techniques. The product is safer and more durable. The internal 8MM rubber elastic pad reduces the impact damage caused by the seat sinking too quickly to the body. The smooth surface of the high-pressure piston rod formed by multiple grinding improves the gas tightness and makes it less likely to leak and lose pressure over time. The smooth high-pressure outer tube and ball bearings make the gas spring rotate smoothly and freely at 360 degrees without any gap.
  • Outer cylinder diameter 50mm (1.97 inches). Inner cylinder diameter 28mm (1.1 inches), 1 degree 26 minutes 16 seconds cone angle is suitable for replacement of 95% of the hydraulic rods on the market, theoretical lifting stroke of 4.7", actual lifting stroke of 4.4" (minus 0.3" slow-descending rubber pad), tail size of 2", please confirm the size before purchasing.
  • Please check whether the control mechanism of your chair is damaged before ordering (Damage of plastic components or deformation of metal components related to the internal height adjustment of the mechanism can also be manifested as problems with the gas cylinder). Confirm your original Cylinder Gas Open Pin Type, outer tube diameter, and Gap between the gas cylinder bottom end face and floor.
  • High quality air pressure rod, so that your use is more comfortable
