Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X600-75
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X600-75 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 600mm 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 SGCJ250X600-75
Delivering 24543 N of thrust at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates a 75 mm external adjuster to fine-tune the extend end position on-site. The nominal 600 mm stroke represents the maximum travel, allowing you to shorten the forward motion down to 525 mm without swapping the unit, while the retract end remains fixed. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, and the G1 pneumatic port handles the massive airflow required for rapid cycling.
Dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures. For vertical deployments, the 24543 N output at 0.5 MPa safely lifts roughly 1251 kg with a 2:1 margin, equating to a safe working load of about 14726 N. Note that TPU seals are unavailable on this 250 mm bore; it uses NBR packings, with a Viton H option for 0-150 C environments. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X600-75 Is Used
Heavy Pallet Upender
Provides the 24543 N push force needed to rotate loaded pallets, using the 75 mm adjuster to dial in the exact tipping angle on-site.
Press Die Setter
Clamps heavy stamping dies into the press bed, trimming the 600 mm extend stroke by 75 mm to accommodate varying die heights without collision.
Bulk Container Sealer
Drives a massive 1251 kg vertical platen to seal large bulk containers, relying on the G1 port for high-volume actuation.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X600-75 the Right Cylinder?
When sizing this unit, the 160 mm bore offers 10053 N and the 200 mm bore provides 15708 N at 0.5 MPa, whereas this 250 mm bore tops out at 24543 N, making it the heavy-duty choice. The 75 mm adjustable window is ideal for sharing a single spare cylinder across multiple stroke variants or finalizing end positions during machine commissioning. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because the 600 mm stroke generates significant leverage, external rod-end guides are mandatory to prevent side-load bending. Without the -S magnet option, position sensing is impossible on this unit.
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 SGCJ250X600-75 FAQ
At 0.5 MPa it generates 24543 N push and 23562 N pull; at 0.7 MPa it outputs 34360 N push and 32986 N pull. The theoretical maximum force is 5006 kgf at 1.0 MPa. It features a 50 mm rod, an M42x2.0 rod thread, a G1 air port, and 60 mm adjustable air cushions at both ends.
The 600 mm nominal stroke is the maximum forward travel. An external stop screw lets you shorten the extend stroke by up to 75 mm on-site, yielding a usable extend range of 525 to 600 mm. The retract end is fixed. This mechanism only sets the end position and does not lock the load; use an external rod lock or pilot-operated check valve to hold a load securely.
