Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X300-50
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X300-50 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 300mm 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 SGCJ250X300-50
Delivering 24543 N of thrust at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder handles heavy industrial positioning. Four steel rods clamp the aluminium barrel to the covers, and the G1 air port feeds the Ø50 mm rod. An external adjuster lets you shorten the extend stroke on-site by up to 50 mm without changing the mount. The nominal 300 mm stroke is the maximum, yielding a usable 250-300 mm range, while the retract end stays fixed.
This design drops into existing ISO 15552 mounting interfaces. It provides a safe working load of roughly 14726 N, lifting about 1251 kg vertically with a 2:1 margin. A 60 mm adjustable air cushion decelerates the piston at both ends. Note that TPU seals are unavailable for Ø250 bores; standard NBR works from -20 to +70 C, while the Viton H option extends to 150 C. This non-magnetic SKU cannot take a sensor.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X300-50 Is Used
Heavy Pallet Forming
Drives large platens in automated palletizers, using the 50 mm extend window to dial in exact package heights without swapping cylinders.
Bulk Valve Actuation
Shifts heavy process valves, relying on the 60 mm adjustable cushion to decelerate the 23562 N pull load smoothly at the fixed retract end.
Press Stroke Tuning
Powers light stamping presses where the external stop screw sets the precise 250-300 mm working depth for varied material thicknesses.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X300-50 the Right Cylinder?
Size this 250 mm bore against the 200 mm option, which offers 15708 N push at 0.5 MPa, or step up if you need the absolute maximum 5006 kgf at 1.0 MPa. The 50 mm adjuster is ideal for sharing a spare across stroke variants or fine-tuning the end position on-site. Mount via FA, LB, TC, FTC, TCM1 or TCM2 brackets. Because this lacks the -S suffix, it cannot accept CMSG, DMSG or EMSG sensors. For any stroke over 500 mm, use a guide rail to prevent side-load damage.
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 SGCJ250X300-50 FAQ
At 0.5 MPa it provides 24543 N push and 23562 N pull. At 0.7 MPa it outputs 34360 N push and 32986 N pull. The theoretical maximum force is 5006 kgf at 1.0 MPa. It uses a G1 port and a 60 mm adjustable cushion.
The external adjuster shortens the extend stroke on-site by up to 50 mm. The nominal 300 mm stroke is the maximum, giving a usable extend range of 250-300 mm. The retract end is fixed. This mechanism sets the end position but does not lock the load; use an external rod lock or pilot-operated check valve to hold a load.
