Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-40
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-40 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 80mm 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 SGCJ250X80-40
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 roughly 14726 N, which translates to lifting about 1251 kg vertically with a 2:1 margin. The unit features a G1 air port and a 60 mm adjustable air cushion at each end.
The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, meaning the usable extend range is 40-80 mm from the 80 mm nominal maximum. You can fine-tune the end position without changing the cylinder itself. Dimensionally interchangeable per the ISO 15552 mounting interface, it drops into existing large-bore fixtures. Note that TPU seals are not available on this 250 mm bore; it uses NBR buffer gaskets, with a Viton H option for 0-150 C environments.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-40 Is Used
Heavy Press Clamping
Provides up to 34360 N of clamping force at 0.7 MPa for securing thick steel plates in a hydraulic press setup, with the 40 mm adjuster tuning the final grip position.
Stamping End Stop
Acts as a robust end stop in a heavy stamping line, using the 60 mm adjustable cushion to decelerate fast-moving carriers safely over a 40-80 mm extend range.
Platform Lowering
Lowers heavy material platforms weighing around 1251 kg, relying on the rigid tie-rod construction to maintain alignment under high vertical loads.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-40 the Right Cylinder?
This 250 mm bore sits at the top of the SGCJ range, offering 24543 N push at 0.5 MPa compared to 15708 N on the 200 mm bore. If you need less force, the 200 mm bore provides a lighter alternative. The 40 mm adjustable window is ideal when you need to share a spare cylinder across stroke variants or fine-tune the end position on-site. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2. Because this SKU lacks the -S suffix, it cannot take a magnetic sensor; you need the -S variant for CMSG/DMSG/EMSG switches. Even at 80 mm stroke, guide the load to prevent side-load wear.
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 SGCJ250X80-40 FAQ
This 250 mm bore cylinder features a G1 air port, a 50 mm rod, and an M42x2.0 rod thread. It generates 24543 N push and 23562 N pull at 0.5 MPa, rising to 34360 N push and 32986 N pull at 0.7 MPa. The theoretical maximum force is 5006 kgf at 1.0 MPa.
The external adjuster lets you shorten the extend stroke on-site by up to 40 mm. The nominal 80 mm stroke is the maximum, giving a usable extend range of 40-80 mm, while the retract end remains fixed. This mechanism sets the end position and does not hold the load; for load holding on air loss, use an external rod lock or pilot-operated check valve.
