Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X50-50S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X50-50S 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.

About the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X50-50S
Delivering massive thrust, this ISO 15552 tie-rod cylinder pushes with 24543 N and pulls with 23562 N at 0.5 MPa. The four steel rods clamp the aluminum barrel securely, and the G1 port handles the high air volume needed for the 250 mm bore. It handles a safe working load of roughly 14726 N, which translates to lifting about 1251 kg vertically with a 2:1 margin.
The -50 code means an external adjuster can shorten the extend stroke by up to 50 mm on-site, letting you fine-tune the end position without swapping the cylinder. Because this is a 250 mm bore, TPU seals are unavailable, but an NBR front-cover packing is standard, with a Viton H option for 0-150 C heat. The -S suffix adds a piston magnet for CMSG, DMSG, or EMSG sensors. Note that the adjustable stop sets position only; it is not a load lock.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X50-50S Is Used
Press Tonnage Tuning
Use the 50 mm extend adjuster to set exact bottom-dead-center on a 1251 kg pressing operation, ensuring perfect crimp depth without repositioning the heavy fixture.
Heavy Stamp Positioning
Leverage the 24543 N push force to drive a large stamping die, tweaking the 50 mm stroke end-point on the fly to accommodate varying material thicknesses.
Pallet Clamp Synchronization
Clamp oversized pallets securely using the G1 port for rapid actuation, relying on the external stop to match the exact clamping distance across multiple cylinders.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X50-50S the Right Cylinder?
As the largest bore, this 250 mm unit sits at the top edge, offering 34360 N push at 0.7 MPa, far exceeding the 200 mm bore which provides 21991 N. If your application needs less force, step down to the 200 mm option. The 50 mm nominal stroke is short, but the 50 mm adjust window is exceptionally useful for synchronizing multiple heavy clamps or setting exact end positions on-site without machining new spacers. Standard SGCJ mountings include FA, LB, TC, FTC, TCM1, and TCM2. The included -S magnet supports position sensing. Because strokes under 500 mm rarely encounter severe buckling, side-load guiding is less critical here than on long-stroke units, though heavy masses still require linear guides.
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 SGCJ250X50-50S FAQ
At 0.5 MPa it pushes with 24543 N and pulls with 23562 N. At 0.7 MPa the push is 34360 N and the pull is 32986 N. The theoretical maximum force is 5006 kgf at 1.0 MPa.
The 50 mm nominal stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 50 mm on-site, giving a usable extend range of 0-50 mm. The retract end remains fixed. This mechanism only sets the end position and does not lock the load.
