Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X300-10S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X300-10S 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 SGCJ250X300-10S
Delivering 24543 N of thrust at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates a magnetic piston for position sensing. Four steel tie rods clamp the aluminum barrel to the covers, providing structural rigidity, while the G1 port handles high flow. The front-cover packing and buffer gasket use NBR seals, as TPU is not available on this 250 mm bore. For high-heat environments up to 150 C, a Viton H seal option is offered.
The -10 code defines an external adjuster that shortens the extend stroke on site by up to 10 mm, letting you fine-tune the end position without changing the cylinder itself. The nominal 300 mm stroke remains the maximum, yielding a usable extend range of 290 to 300 mm, while the retract end is fixed. This robust unit handles a safe working load of about 14726 N, which translates to lifting roughly 1251 kg vertically with a 2:1 safety margin.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X300-10S Is Used
Heavy Pallet Forming
Drives large platens to compress pallets, using the 10 mm extend adjuster to dial in exact package thickness without repositioning the frame.
High-Flow Gate Actuation
Shifts heavy industrial bulk-handling gates where the G1 port and 24543 N thrust at 0.5 MPa easily overcome material resistance.
Industrial Pressing
Applies up to 34360 N of force at 0.7 MPa for seating large bearings, relying on the 60 mm adjustable air cushions to decelerate the load.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X300-10S the Right Cylinder?
This 250 mm bore sits at the top of the SGCJ range, offering 24543 N push at 0.5 MPa compared to 15708 N on the 200 mm bore, making it the choice when maximum pneumatic force is required. Stepping down to the 200 mm option saves space if your application only needs 15708 N. The adjustable stroke feature is highly useful for sharing a single spare across multiple stroke variants or for final end-position tuning on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. The -S suffix means a magnet is built in for CMSG, DMSG, or EMSG sensors. Because the stroke is 300 mm, ensure external guide rails are used 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 SGCJ250X300-10S FAQ
This 250 mm bore cylinder features a G1 air port and a 50 mm rod. It generates 24543 N push and 23562 N pull at 0.5 MPa, increasing to 34360 N push and 32986 N pull at 0.7 MPa. The theoretical maximum force is 5006 kgf at 1.0 MPa.
The -10 code provides an external adjuster that lets you shorten the extend stroke by up to 10 mm on site. The nominal 300 mm stroke is the maximum, giving a usable extend range of 290 to 300 mm, while the retract end remains fixed. This stop sets the end position and is not a load lock.
