Our take on the JIAN YA NA Chair Gas Lift Cylinder Replacement Heavy Duty Pneumatic Shock Hydraulic Piston,HC40

The Jian Ya Na HC40 is a replacement gas lift cylinder for office chairs, the pneumatic piston that raises and lowers the seat. It uses a 50mm base cylinder and is rated for up to 110kg, so it fits most standard five-star chair bases and typical adult users. It is a generic part rather than a branded mechanism, so the main thing to check before buying is the fit: base diameter and the stroke length your chair needs. Buyers replacing a sagging or stuck cylinder get a working height adjustment again, but expect to confirm measurements yourself since fit varies by chair.
