Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-100
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-100 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 500mm 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 SGCJ250X500-100
Delivering massive thrust, 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 aluminium barrel to the covers, providing structural rigidity for heavy-duty automation. It handles a safe working load of roughly 14726 N, which translates to lifting about 1251 kg vertically with a 2:1 margin.
The external adjuster allows you to shorten the extend stroke on-site by up to 100 mm, giving a usable range of 400 to 500 mm without changing the cylinder itself. This model uses a G1 port and a 50 mm rod with an M42x2.0 thread. Because this is a 250 mm bore, TPU seals are not available; instead it uses NBR components, with a Viton H option for 0 to 150 C environments.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-100 Is Used
Heavy Pallet Lifts
Lifts loaded pallets weighing up to 1251 kg vertically, using the 100 mm extend window to fine-tune the exact stopping height at different docking stations.
Press End Tuning
Acts as a heavy-duty press cylinder where the on-site stroke adjustment compensates for material thickness variations without repositioning the entire fixture.
Bulk Material Diversion
Pushes heavy bulk material diverters on high-capacity lines, using the 60 mm adjustable air cushions to decelerate the massive 50 mm rod smoothly.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-100 the Right Cylinder?
When sizing this unit against its neighbours, stepping down to a 200 mm bore drops the 0.5 MPa push force to 15708 N, while this 250 mm bore provides 24543 N. If you need even more power, note that 250 mm is the largest standard SGCJ bore. The 100 mm adjustable window is ideal for fine-tuning end positions on-site or sharing spares across stroke variants. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2 brackets. This specific SKU lacks the -S suffix, so it cannot accept CMSG, DMSG or EMSG magnetic sensors. Because the stroke is 500 mm, always use external guides to prevent rod bending under 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 SGCJ250X500-100 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 external adjuster shortens the extend stroke on-site by up to 100 mm, giving a usable extend range of 400 to 500 mm from the 500 mm nominal maximum. The retract end remains fixed. This stop only sets the end position; it does not lock the load.
