Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X300-40
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X300-40 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 SGCJ250X300-40
Generating massive thrust with 24543 N of push force at 0.5 MPa, this ISO 15552 tie-rod cylinder handles heavy-duty positioning. The four steel tie rods clamp the aluminum barrel securely, and the G1 air port supplies the volume needed for the 250 mm bore. It delivers a safe working load of about 14726 N, easily lifting roughly 1251 kg vertically with a 2:1 margin.
The external adjuster allows you to shorten the extend stroke on-site by up to 40 mm, giving a usable range of 260-300 mm without changing the cylinder itself. Because this is a 250 mm bore, TPU seals are unavailable; instead, NBR packings are standard, with a Viton H option for 0-150 C environments. This specific SKU lacks a magnet, meaning it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X300-40 Is Used
Heavy Stamping Press
Provides the 34360 N push force at 0.7 MPa needed to form thick plate metal, using the 40 mm adjuster to dial in the exact bottom dead center.
Pallet Stopper Gate
Acts as a high-force barrier in automated dispatch lanes, shortening the extend stroke by 40 mm to accommodate varying pallet overhangs.
Rotary Indexer Brake
Halts large rotary tables using the full 5006 kgf maximum capacity, relying on the 60 mm cushions to absorb the stopping energy.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X300-40 the Right Cylinder?
When sizing this unit, the 160 mm bore provides 10053 N of push at 0.5 MPa, while the 250 mm bore tops the range at 24543 N, making it the heavy-lift choice. The 40 mm adjustable window is ideal for fine-tuning the end position on-site or sharing a spare across stroke variants. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. For any stroke length at or above 500 mm, use an external guide to prevent side-load damage. Note that this non-magnet version cannot support position sensing.
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 SGCJ250X300-40 FAQ
At 0.5 MPa it provides 24543 N push and 23562 N pull. At 0.7 MPa it delivers 34360 N push and 32986 N pull. The theoretical maximum force is 5006 kgf at 1.0 MPa. It features a G1 port and a 50 mm rod.
An external stop screw lets you shorten the extend stroke on-site by up to 40 mm, yielding a usable extend range of 260-300 mm from the 300 mm nominal maximum. The retract end remains fixed. This mechanism sets the end position and is not a load lock.
