Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-100S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-100S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 800mm 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 SGCJ250X800-100S
Delivering massive thrust for heavy industry, this 250 mm bore tie-rod actuator pushes with 24543 N at 0.5 MPa. It is a genuine ISO 15552 cylinder, dimensionally interchangeable per the standard mounting interface to drop into existing large-bore fixtures. Four steel tie rods clamp the aluminum barrel, and the G1 port handles high flow volumes. The -100S code means a built-in magnet for CMSG/DMSG/EMSG sensors and an external adjuster that shortens the extend stroke by up to 100 mm on-site.
With a nominal 800 mm stroke, you can fine-tune the extend end position down to 700 mm without changing the hardware. It provides a safe working load of about 14726 N, lifting roughly 1251 kg vertically with a 2:1 margin. Note that TPU seals are unavailable for this bore; it uses NBR, with a Viton H option for 0-150 C environments. The 60 mm adjustable air cushions decelerate the piston but do not lock the load on air loss.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-100S Is Used
Heavy Pallet Lifts
Raises 1251 kg loaded pallets vertically with a 2:1 safety margin, using the 100 mm external adjuster to set precise stopping heights for different dock levels.
Press Ejection
Ejects large formed parts with 24543 N of force at 0.5 MPa, relying on the 60 mm adjustable cushions to decelerate the 50 mm rod smoothly at the end of the 800 mm stroke.
Bulk Material Diversion
Swings heavy diverter gates on high-capacity lines, where the built-in magnet triggers CMSG position sensors to confirm gate placement under harsh conditions.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-100S the Right Cylinder?
Size this 250 mm bore against the 200 mm option, which yields 15708 N push at 0.5 MPa, or step up if you need the absolute maximum 5006 kgf at 1.0 MPa. The 100 mm adjustable window lets you standardize on one 800 mm cylinder and dial in the exact extend position across multiple fixtures, saving unique spare-part SKUs. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. The -S suffix equips the piston for CMSG/DMSG/EMSG electronic or reed switches. Because the 800 mm stroke generates high rod bending moments, always use external guides and rod-end support 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 SGCJ250X800-100S FAQ
This 250 mm bore cylinder uses a G1 air port and a M42x2.0 rod thread. It generates 24543 N push and 23562 N pull at 0.5 MPa, 34360 N push and 32986 N pull at 0.7 MPa, with a theoretical maximum of 5006 kgf at 1.0 MPa.
The nominal 800 mm stroke is the maximum extend length. An external stop screw lets you shorten the extend stroke by up to 100 mm on-site, giving a usable range of 700-800 mm for fine-tuning the end position. The retract end remains fixed, and this stop is not a load lock.
