Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-30S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-30S 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.

About the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-30S
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 structural rigidity. The G1 air port feeds the 50 mm piston rod, which features an M42x2.0 thread and 60 mm adjustable air cushions at both ends.
The external adjuster shortens the extend stroke on-site by up to 30 mm, letting you fine-tune the end position without changing the cylinder. This 800 mm stroke model yields a usable extend range of 770 to 800 mm, while the retract end stays fixed. It handles a safe working load of about 14726 N, which translates to lifting roughly 1251 kg vertically with a 2:1 margin. The -S suffix adds a piston magnet for CMSG, DMSG, or EMSG sensors. Note that TPU seals are unavailable for 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 SGCJ250X800-30S Is Used
Heavy Press Ejection
Fine-tune the 30 mm extend window on-site to perfectly time the ejection of large steel plates from a hydraulic press without repositioning the cylinder.
Pallet Lift Positioning
Lift loaded pallets up to 1251 kg vertically with a 2:1 margin, adjusting the extend end-point to match varying pallet heights on the fly.
Mold Clamp Adjustment
Secure heavy injection molds by dialing in the exact 770 to 800 mm clamping position externally, compensating for minor mold height differences.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-30S the Right Cylinder?
Size this 250 mm bore against the neighboring 200 mm option, which provides 15708 N of push at 0.5 MPa. The 250 mm bore is the top edge here, generating 24543 N at 0.5 MPa and a theoretical maximum of 5006 kgf at 1.0 MPa. The adjustable stroke is ideal when you need on-site end-position tuning or want to share a spare cylinder across multiple stroke variants. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because the -S magnet is present, you can fit CMSG, DMSG, or EMSG switches. At an 800 mm stroke, large-bore rods are prone to bending; always use external guides and rod-end support to manage side loads.
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 SGCJ250X800-30S FAQ
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 force is 5006 kgf at 1.0 MPa. The air port is G1, the rod is 50 mm with an M42x2.0 thread, and it includes 60 mm adjustable cushions.
An external stop screw lets you shorten the extend stroke on-site by up to 30 mm. The nominal 800 mm stroke is the maximum, giving a usable extend range of 770 to 800 mm. The retract end is fixed. This mechanism sets the end position but does not lock the load; use an external rod lock or pilot-operated check valve if you need to hold a load on air loss.
