The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X50-30 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 50mm 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, this ISO 15552 tie-rod cylinder pushes with 24543 N at 0.5 MPa. Four steel rods clamp the aluminum barrel, and the G1 port feeds the 50 mm piston rod. It handles a safe working load near 14726 N, lifting roughly 1251 kg vertically with a 2:1 margin.
The external adjuster shortens the extend stroke on-site by up to 30 mm, letting you fine-tune the end position without swapping parts. The nominal 50 mm stroke remains the maximum. Because this is a 250 mm bore, TPU seals are unavailable; NBR is standard, with a Viton H option for 0-150 C heat.

| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 24544 N | 23562 N |
| 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.

|---|---|
| 250 | Bore size in mm (125 / 160 / 200 / 250). |
| ×50 | Stroke length in mm. |
| -S | Optional built-in magnet for CMSG / DMSG / EMSG sensors. |
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.
Fine-tune the 50 mm extend stroke on-site by up to 30 mm to set exact contact depth on large stamping presses without changing the cylinder.
Lift approximately 1251 kg vertically with a 2:1 safety margin, using the 24543 N push force to raise heavy industrial platforms.
Adjust the extend window on-site to synchronize clamping force across multiple large fixtures, ensuring perfect part alignment.
This 250 mm bore sits at the top of the SGCJ range, pushing 24543 N versus 15708 N for the 200 mm bore at 0.5 MPa. The 30 mm adjuster is perfect for synchronizing multiple heavy stops or sharing spares across stroke variants. Mount via FA, LB, TC, FTC, TCM1, or TCM2 brackets. This SKU lacks a magnet, so it cannot take CMSG/DMSG/EMSG sensors; choose the -S version if you need position detection. Keep side loads minimized with external guides.
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. It uses a G1 port.
An external stop screw shortens the extend stroke by up to 30 mm on-site. The nominal 50 mm stroke is the maximum, giving a usable extend range of 20-50 mm. The retract end is fixed. This screw sets end position and does not lock the load.
