Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-10
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-10 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 SGCJ250X800-10
Delivering massive thrust with a 24543 N push at 0.5 MPa, this ISO 15552 tie-rod cylinder handles about 14726 N of safe working load, roughly 1251 kg lifted vertically with a 2:1 margin. Four steel tie rods clamp the aluminum barrel to the covers, providing structural rigidity for heavy-duty operations. The bore dictates a G1 air port, a Ø50 mm rod, and a 60 mm adjustable air cushion at each end.
An external adjuster allows you to shorten the extend stroke on-site by up to 10 mm, meaning the usable extend range is 790-800 mm while the retract end remains fixed. This mechanism lets you fine-tune the end position without physically changing the cylinder. Note that TPU seals are not available on this Ø250 bore; it uses NBR buffers, though a Viton H option extends the temperature range from 0 to 150 C.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-10 Is Used
Heavy Press Clamping
Provides 34360 N of extend force at 0.7 MPa for securing large steel plates in a hydraulic press, using the 10 mm adjuster to dial in the exact clamping datum.
Pallet Lift Gates
Lifts heavy loaded pallets vertically, safely handling around 1251 kg with a 2:1 margin, while the 60 mm cushions absorb kinetic energy at the end of travel.
Bulk Material Diversion
Actuates a heavy diverter gate on a bulk aggregate conveyor, using the ISO 15552 mounting interface to drop directly into existing heavy-duty fixtures.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-10 the Right Cylinder?
When sizing this 250 mm bore unit, stepping down to a 200 mm bore yields 15708 N of push at 0.5 MPa, whereas this 250 mm bore provides 24543 N. The adjustable stroke feature is highly beneficial when you need on-site end-position tuning or want to share a spare cylinder across slightly different stroke variants. SGCJ mounting options include FA, LB, TC, FTC, TCM1, and TCM2. Because this is a no-S SKU, it cannot take a magnetic switch; you would need the -S variant for CMSG/DMSG/EMSG sensors. With an 800 mm stroke, large-bore side-load risks are high, so external rod-end support and guides are essential to prevent rod bending.
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 SGCJ250X800-10 FAQ
At 0.5 MPa it provides 24543 N push and 23562 N pull. At 0.7 MPa it provides 34360 N push and 32986 N pull. The theoretical max force is 5006 kgf at 1.0 MPa. It features a Ø50 mm rod, a G1 port, M42x2.0 rod thread, and 60 mm adjustable cushions. Operating pressure is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
The nominal 800 mm stroke is the maximum extend length. The external adjuster lets you shorten the extend stroke on-site by up to 10 mm, giving a usable extend range of 790-800 mm. The retract end is fixed. This adjuster sets the end position and does not hold the load; for load holding on air loss, you need an external rod lock or pilot-operated check valve.
