Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-100S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-100S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 450mm 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 SGCJ250X450-100S
Delivering massive thrust in a large-bore format, this 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, yielding high structural rigidity for heavy-duty automation. A built-in piston magnet (-S) supports CMSG, DMSG, and EMSG position switches.
The external adjuster allows you to shorten the extend stroke on-site by up to 100 mm, giving a usable range of 350 to 450 mm without changing the cylinder itself. This is ideal for fine-tuning end positions across shared machine designs. It handles a safe working load of about 14726 N, which translates to lifting roughly 1251 kg vertically with a 2:1 margin. Pneumatic supply connects via a G1 port, and the NBR seals (Viton H available for 0-150 C) operate from -20 to +70 C.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-100S Is Used
Heavy Pallet Forming
Lifts and compresses large pallet loads with a 1251 kg vertical lift capacity, using the 100 mm adjuster to tune the final press height on-site.
Press Tonnage Tuning
Provides 24543 N of raw push force for heavy stamping tasks, allowing operators to dial in the exact 350 to 450 mm extend position without mechanical shims.
Automated Guided Cart Stops
Halts heavy AGV carts using a robust 50 mm rod, relying on the 60 mm adjustable air cushions to decelerate the impact smoothly at the end of travel.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-100S the Right Cylinder?
When sizing this unit, stepping down to a 200 mm bore yields 15708 N push at 0.5 MPa, while this 250 mm bore provides 24543 N for high-edge demands. The adjustable stroke is perfect for standardizing spare parts across machines needing slightly different end positions. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. The -S magnet enables electronic or reed sensor tracking. Because the 450 mm stroke generates leverage, always use an external guide to prevent side-load damage to the rod.
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 SGCJ250X450-100S FAQ
This 250 mm bore cylinder features a G1 air port and a 50 mm rod. It delivers 24543 N push and 23562 N pull at 0.5 MPa, 34360 N push and 32986 N pull at 0.7 MPa, with a theoretical maximum of 5006 kgf at 1.0 MPa.
The external stop screw lets you shorten the extend stroke on-site by up to 100 mm, providing a usable extend range of 350 to 450 mm. The nominal 450 mm stroke is the maximum, and the retract end remains fixed. This mechanism sets the end position and does not lock the load.
