Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X600-40S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X600-40S 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 SGCJ250X600-40S
Delivering 24543 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates an external adjuster that trims the extend stroke by up to 40 mm on site. The nominal 600 mm stroke remains the maximum travel, yielding a usable 560-600 mm extend range while the retract end stays fixed. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity. Equipped with a -S piston magnet, it supports CMSG, DMSG, and EMSG electronic or reed switches for position sensing.
At 0.5 MPa it safely handles a working load of about 14726 N, translating to roughly 1251 kg lifted vertically with a 2:1 safety margin. The G1 air port, M42x2.0 rod thread, and 60 mm adjustable air cushions at both ends manage the massive 5006 kgf maximum theoretical output. Note that TPU seals are unavailable for this 250 mm bore; standard NBR packings operate from -20 to +70 C, with a Viton H option extending heat resistance to 150 C. The cushion decelerates the load but does not lock it, so fit an external rod lock or pilot-operated check valve if you need to hold position on air loss.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X600-40S Is Used
Heavy Pallet Lifting
Raises 1251 kg loaded pallets in distribution hubs, using the 40 mm extend adjuster to dial in exact docking heights without recalibrating the entire pneumatic circuit.
Press Ejection Setup
Ejects heavy stamped metal parts from large presses, relying on the 60 mm adjustable air cushions to smoothly decelerate the massive 5006 kgf peak force at stroke end.
Automated Storage Retrieval
Actuates heavy storage crane arms where the -S magnet and EMSG sensors confirm reach, while the external stop screw precisely matches varying rack bay depths.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X600-40S the Right Cylinder?
Size this 250 mm bore against the neighboring 200 mm option, which provides 15708 N push at 0.5 MPa, or step up if you need the absolute maximum 5006 kgf theoretical force at 1.0 MPa. The 40 mm adjustable window is ideal for sharing a single spare cylinder across multiple stroke variants, fine-tuning the end position on-site without mechanically remounting the body. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets, all conforming strictly to ISO 15552 mounting interface dimensions. Because the 600 mm stroke creates leverage, external guide rails and rod-end support are mandatory 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 SGCJ250X600-40S FAQ
This 250 mm bore cylinder features a G1 air port and delivers 24543 N push / 23562 N pull at 0.5 MPa, and 34360 N push / 32986 N pull at 0.7 MPa. The theoretical maximum force is 5006 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 40 mm on site, giving a usable extend range of 560-600 mm. The nominal 600 mm is the maximum travel, and the retract end remains fixed. This mechanism sets the end position and does not lock the load.
