Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-30
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-30 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 SGCJ250X800-30
Generating 24543 N of push force at 0.5 MPa, this ISO 15552 tie-rod cylinder handles heavy-duty positioning with ease. Four steel tie rods clamp the aluminum barrel to the covers, delivering structural rigidity for large-bore operations. Air enters via a G1 port, driving a 50 mm piston rod with an M42x2.0 thread. The adjustable air cushions span 60 mm at each end to absorb kinetic energy smoothly.
The -30 code defines an external adjuster that shortens the extend stroke on-site by up to 30 mm, allowing you to fine-tune the end position from 770 to 800 mm without changing the cylinder itself. It drops into existing fixtures dimensionally interchangeable per the ISO 15552 mounting interface. Because this is a 250 mm bore, TPU seals are unavailable, but a Viton H option raises the operating range to 0-150 C. This SKU lacks a magnet, so it cannot take a magnetic switch. For lifting tasks, expect a safe working load around 14726 N, which translates to lifting roughly 1251 kg vertically with a 2:1 margin.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-30 Is Used
Heavy Pallet Lifting
Raises loaded pallets in automated distribution hubs, utilizing the 30 mm extend adjuster to dial in exact stacking heights on the fly.
Press Ejection
Ejects dense metal components from hydraulic presses, relying on the 60 mm adjustable cushions to stop the 800 mm stroke smoothly.
Stamping Positioning
Feeds thick plate stock into stamping machinery, tweaking the extend end point to compensate for varying material thicknesses without remounting.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-30 the Right Cylinder?
Size this 250 mm bore against the 200 mm option, which provides 15708 N of push at 0.5 MPa, or step up if you need the absolute maximum 5006 kgf at 1.0 MPa. The adjustable stroke is ideal when you need on-site end-position tuning or want a shared spare across stroke variants. SGCJ mounting options include FA, LB, TC, FTC, TCM1, and TCM2. Because this is an 800 mm stroke, large-bore long strokes need rod-end support and external guides to prevent rod bending under side loads. Note that this non-magnet SKU cannot accept a CMSG, DMSG, or EMSG sensor.
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 SGCJ250X800-30 FAQ
This 250 mm bore cylinder features a G1 port and generates 24543 N push and 23562 N pull at 0.5 MPa. At 0.7 MPa, it outputs 34360 N push and 32986 N pull. The theoretical maximum force is 5006 kgf at 1.0 MPa.
The -30 code indicates an external adjuster that lets you shorten the extend stroke on-site by up to 30 mm. The nominal 800 mm stroke is the maximum, giving you a usable extend range of 770 to 800 mm, while the retract end remains fixed. This mechanism sets the end position and is not a load lock.
