The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X700-40 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 700mm 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 for heavy industry, this large-bore ISO 15552 tie-rod cylinder pushes with 24543 N and pulls with 23562 N at 0.5 MPa. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity. It handles a safe working load of about 14726 N, which translates to lifting roughly 1251 kg vertically with a 2:1 safety margin. The G1 air port matches the 250 mm bore size.
The -40 code means an external adjuster can shorten the extend stroke on site by up to 40 mm, giving a usable range of 660 to 700 mm without changing the cylinder itself. This lets you fine-tune the end position precisely. The retract end remains fixed. For high-heat environments up to 150 C, specify the Viton H seal option, as standard TPU is not available on this 250 mm bore. Note this SKU lacks a magnet and cannot take a sensor.

| 0.7 MPa | 34361 N | — |
| Max (@1.0 MPa) | 5006 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety 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.
Use the 660 to 700 mm extend window to dial in the exact clamping depth on large press assemblies, leveraging 24543 N of thrust at 0.5 MPa.
Fine-tune the stopping end position for oversized pallets on a conveyor without physically remounting the cylinder or changing the fixed retract end.
Adjust the external stop screw to set the precise open angle of heavy industrial doors, ensuring a perfect seal without mechanical interference.
When sizing this 250 mm bore, stepping down to a 200 mm bore drops the 0.5 MPa push force to 15708 N, while this unit provides 24543 N. As the largest standard bore, it sits at the top edge of the range, yielding a theoretical maximum of 5006 kgf at 1.0 MPa. The adjustable stroke is ideal when you need shared spares across stroke variants or on-site end-position tuning. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. Because the 700 mm stroke is long, always use external guides to prevent rod bending and manage side loads. Without the -S suffix, this cylinder cannot host CMSG, DMSG, or EMSG sensors.
Quick checklist
At 0.5 MPa it pushes 24543 N and pulls 23562 N. At 0.7 MPa it pushes 34360 N and pulls 32986 N. The theoretical maximum is 5006 kgf at 1.0 MPa.
The nominal 700 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on site by up to 40 mm, yielding a usable 660 to 700 mm range. The retract end is fixed. This mechanism sets end position and is not a load lock.
