Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-50
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-50 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 900mm 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 SGCJ250X900-50
Delivering massive thrust for heavy industry, 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 aluminum barrel to the covers, providing rigid structural integrity for demanding cycles. It handles a safe working load of roughly 14726 N, which translates to lifting about 1251 kg vertically with a 2:1 safety margin.
The external adjuster lets you shorten the extend stroke on-site by up to 50 mm, meaning the usable extend range is 850 to 900 mm while the retract end remains fixed. You can fine-tune the end position without physically changing the cylinder. This genuine ISO 15552 mounting interface drops directly into existing large-bore fixtures. It uses a G1 air port, a 50 mm rod with an M42x2.0 thread, and 60 mm adjustable air cushions at both ends. Note that TPU seals are not offered on this 250 mm bore; it uses NBR packings, with a Viton H option for 0 to 150 C environments.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-50 Is Used
Heavy Pallet Lifting
Raises loaded pallets in automated warehouses, using the 50 mm extend adjustment to dial in exact upper stop positions without repositioning the frame.
Press Ejection
Ejects heavy formed parts from large presses, relying on the 60 mm cushions to decelerate the massive 50 mm rod smoothly at the end of a 900 mm travel.
Stamping Clamp
Drives large clamping tools in stamping lines where the 850 to 900 mm extend window allows operators to tune the final material contact point on the factory floor.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-50 the Right Cylinder?
When sizing this unit against its neighbors, 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 at the top end of the standard range. The 50 mm adjustable window is highly useful when you need to share a single spare cylinder across multiple stroke variants or dial in a precise end position on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this is a no-S SKU, it cannot accept a magnetic switch; you would need the -S variant to use CMSG, DMSG, or EMSG sensors. At a 900 mm stroke, the long rod requires external guide rails to prevent side-load bending and premature seal wear.
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 SGCJ250X900-50 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. It features a 250 mm bore, a 50 mm rod, an M42x2.0 rod thread, a G1 air port, and 60 mm adjustable air cushions. The operating speed range is 30 to 500 mm/s.
The nominal 900 mm stroke is the maximum travel. The external adjuster lets you shorten the extend stroke on-site by up to 50 mm, giving a usable extend range of 850 to 900 mm. The retract end is fixed. This mechanism sets the end position but does not lock the load; if air is lost, the piston drifts. For load holding you must add an external rod lock or a pilot-operated check valve.
