Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-50S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-50S 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 SGCJ250X800-50S
Delivering massive thrust for heavy industry, this large-bore ISO 15552 tie-rod cylinder pushes with 24543 N at 0.5 MPa. The four steel tie rods clamp the aluminum barrel securely to the covers, and the G1 port feeds the 50 mm piston rod. A built-in magnet enables CMSG, DMSG or EMSG sensors for position feedback.
The external adjuster lets you shorten the extend stroke on site by up to 50 mm, meaning your usable extend range is 750 to 800 mm while the retract end stays fixed. This on-site tuning is ideal for dialing in end positions without changing the cylinder. It handles a safe working load of about 14726 N, which means it can vertically lift roughly 1251 kg with a 2:1 safety margin.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-50S Is Used
Heavy Press Ejection
Fine-tune the 50 mm extend window on site to perfectly eject large stamped parts without recalibrating the entire press line.
Pallet Positioning
Shift heavy loaded pallets with 24543 N of thrust, adjusting the end stop to match varying pallet depths on the fly.
Foundry Mold Clamping
Secure heavy foundry molds and tweak the clamping reach up to 50 mm to accommodate different mold frame widths.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-50S the Right Cylinder?
When sizing this unit, the smaller 200 mm bore yields 15708 N push at 0.5 MPa, whereas this 250 mm bore provides 24543 N. The adjustable stroke is a major selection advantage for shared spares across stroke variants. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2. Because this is an 800 mm stroke, you must use external guides to prevent rod bending and 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.
