Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X250-50
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X250-50 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 250mm 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 SGCJ250X250-50
Delivering 24543 N of thrust at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder is built for heavy-duty positioning. Four steel tie rods clamp the aluminum barrel to the covers, and the G1 air port feeds a 50 mm rod with an M42x2.0 thread. It handles a safe working load of about 14726 N, which translates to lifting roughly 1251 kg vertically with a 2:1 margin.
The -50 code means an external adjuster can shorten the extend stroke on-site by up to 50 mm, letting you fine-tune the 200 to 250 mm end position without changing the cylinder itself. Because this is a 250 mm bore, TPU seals are not available; it uses NBR buffer gaskets, with a Viton H option for 0 to 150 C heat. This non-magnetic SKU cannot take a sensor, though the -S variant adds a magnet for CMSG/DMSG/EMSG switches.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X250-50 Is Used
Heavy Pallet Lifts
Raises loaded pallets in automated distribution hubs, using the 50 mm stroke adjuster to dial in the exact discharge height for different conveyor lines.
Hydraulic Press Tending
Shuttles heavy steel blanks into a forming press, leveraging the 24543 N push force and fine-tuning the extend position to match varying die depths.
Large Mold Ejection
Ejects dense injection molds from stationary platens, relying on the rigid tie-rod frame and on-site stroke shortening to prevent over-travel.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X250-50 the Right Cylinder?
At the top of the SGCJ range, this 250 mm bore pushes 24543 N at 0.5 MPa; stepping down to a 200 mm bore drops that to 15708 N, so only choose the 250 when you need that extra force. The 50 mm adjustable window is ideal for sharing a spare across stroke variants or finalizing end positions on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. For any stroke over 500 mm, use a guide rail to prevent side-load damage. Note that this plain cylinder drifts on air loss—the cushion only decelerates—so fit an external rod lock for held 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 SGCJ250X250-50 FAQ
It provides 24543 N push and 23562 N pull at 0.5 MPa, rising to 34360 N push and 32986 N pull at 0.7 MPa, with a theoretical max of 5006 kgf at 1.0 MPa. The air port is G1, the rod is 50 mm, and it has a 60 mm adjustable air cushion at each end.
The -50 indicates an external stop screw that lets you shorten the extend stroke by up to 50 mm on-site, giving a usable extend range of 200 to 250 mm. The nominal 250 mm stroke is the maximum, and the retract end remains fixed. This mechanism sets the end position and does not lock the load.
