The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-50 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 800mm stroke, G1 air ports and adjustable end cushioning. Its large-bore tie-rod build delivers high thrust and drops into standardized ISO 15552 mounting on heavy automation.
Delivering massive thrust in a large-bore format, this ISO 15552 tie-rod cylinder pushes with 24543 N at 0.5 MPa. Four steel rods clamp the aluminum barrel to the covers, yielding a rigid frame that drops directly into existing ISO 15552 mounting-interface fixtures. The G1 air port feeds the 50 mm rod, driving heavy loads at 30-500 mm/s.
An external adjuster lets you shorten the extend stroke on-site by up to 50 mm, meaning the usable extend range is 750-800 mm while the retract end stays fixed. You can fine-tune the end position without swapping the cylinder. This bore omits TPU seals and uses NBR packings, though a Viton H option extends the temperature range to 150 C. Handling a safe working load of roughly 14726 N, it lifts about 1251 kg vertically with a 2:1 margin.

SGC-family variants: SGC (double acting), SGCD (double rod), SGCJ (adjustable stroke). Mounting: LB / FA / FB / CA / CB / CR / TC / FTC / TCM1 / TCM2. Seals: TPU (blank) / Viton H / NBR N.
Raises 1251 kg palletized materials vertically with a 2:1 safety margin, using the 50 mm adjuster to set the exact lift height for different dock levels.
Provides 24543 N of clamping force at 0.5 MPa, allowing operators to shorten the extend stroke on-site by 50 mm to accommodate varying material thicknesses.
Handles heavy aggregate flow diversion where the 750 to 800 mm extend range is fine-tuned to match changing conveyor belt widths without changing the cylinder.
This 250 mm bore sits at the top of the SGCJ range; stepping down to a 200 mm bore drops the 0.5 MPa push force to 15708 N. The adjustable stroke is ideal when you need to share one spare across slightly different machine stroke variants or dial in the exact end position during commissioning. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2. Because this is a plain SKU without an -S suffix, it cannot accept CMSG, DMSG or EMSG magnetic sensors. Finally, the 800 mm stroke demands external guide rails to prevent rod bending under side loads.
Quick checklist
At 0.5 MPa it pushes with 24543 N and pulls with 23562 N. At 0.7 MPa the push is 34360 N and the pull is 32986 N. The theoretical maximum force is 5006 kgf at 1.0 MPa. It uses a G1 port and a 50 mm rod.
The nominal 800 mm stroke is the maximum extend length. An external stop screw lets you shorten the extend stroke on-site by up to 50 mm, giving a usable extend range of 750 to 800 mm while the retract end remains fixed. This mechanism sets the end position and does not lock the load.
