Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-40S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-40S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 450mm 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.

About the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-40S
Delivering massive output for heavy-duty automation, this large-bore ISO 15552 tie-rod cylinder generates 24543 N of push force at 0.5 MPa. Four steel tie rods clamp the aluminium barrel to the covers for structural rigidity, while the G1 air port feeds the Ø50 mm piston rod. Because this is a -S SKU, a built-in magnet supports CMSG, DMSG and EMSG switches for exact position detection.
The -40 code defines an external stop-screw window that shortens the extend stroke on-site by up to 40 mm, yielding a usable 410 to 450 mm stroke without changing the cylinder itself. This on-site end-position tuning is ideal for sharing spares across stroke variants. The retract end remains fixed. With a safe working load of roughly 14726 N, it can lift about 1251 kg vertically with a 2:1 margin. Note that TPU seals are unavailable on this 250 mm bore; NBR is standard, with a Viton H option for 0 to 150 C environments.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-40S Is Used
Press Fit Tuning
Use the 40 mm extend adjuster to set the exact bottoming position for pressing bearings, ensuring perfect insertion depth without remounting the cylinder.
Pallet Stop Calibration
Adjust the extend stroke on-site to act as a precise stop for varying pallet sizes, leveraging the 1251 kg vertical lift capacity for heavy loads.
Heavy Mold Clamping
Secure large injection molds with 24543 N of push at 0.5 MPa, using the external stop screw to dial in the exact clamping distance.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-40S the Right Cylinder?
Size this 250 mm bore against the 200 mm option, which provides 15708 N of push at 0.5 MPa, or evaluate if the maximum 5006 kgf output at 1.0 MPa is required. The adjustable stroke feature helps fine-tune the extend end position on-site, allowing one spare cylinder to cover multiple stroke variants. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2 brackets. The -S magnet enables CMSG, DMSG and EMSG sensors. For any stroke at or above 500 mm, use a guide rail to prevent side-load damage to the rod seals.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Long-stroke side load — support the rod end
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load; support long strokes at the rod end.
- check Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/CR/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-40S FAQ
This 250 mm bore cylinder has a G1 air port and a Ø50 mm rod. It delivers 24543 N push and 23562 N pull at 0.5 MPa, 34360 N push and 32986 N pull at 0.7 MPa, and a theoretical maximum of 5006 kgf at 1.0 MPa.
The -40 code provides an external stop screw that lets you shorten the extend stroke on-site by up to 40 mm. The usable extend range is 410 to 450 mm, with 450 mm being the maximum. The retract end is fixed, and this stop only sets the end position; it does not lock the load.
