Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X75-30
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X75-30 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 75mm 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 SGCJ250X75-30
Delivering massive thrust in a compact footprint, this large-bore ISO 15552 tie-rod cylinder pushes with 24543 N at 0.5 MPa. The four steel tie rods clamp the aluminium barrel securely to the covers, and the G1 port handles the high air volume required for rapid cycling. A true double-acting single-rod unit, it drops directly into existing ISO 15552 mounting interface fixtures without redesign.
The -30 code defines an external adjuster that shortens the extend stroke on site by up to 30 mm, letting you fine-tune the end position without changing the cylinder itself. Usable extend travel becomes 45 to 75 mm, while the retract end remains fixed. It handles a safe working load of about 14726 N, which means you can vertically lift roughly 1251 kg with a 2:1 safety margin. Note that TPU seals are unavailable for this 250 mm bore; standard NBR packing handles -20 to +70 C, with a Viton H option for 0-150 C heat.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X75-30 Is Used
Heavy Pallet Pressing
Exerts 24543 N at 0.5 MPa to seat heavy components, with the 30 mm adjuster trimming the extend stop to match varying pallet thicknesses.
Stamp End Tuning
Shortens the 75 mm extend stroke down to 45 mm on site to set precise stamping depth without swapping out the entire cylinder body.
High-Flow Actuation
Leverages the G1 port and 250 mm bore for rapid high-force valve operations where exact travel limits must be dialed in externally.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X75-30 the Right Cylinder?
This 250 mm bore sits at the top of the SGCJ range, pushing 24543 N at 0.5 MPa; if you need less force, step down to the 200 mm bore for 15708 N. The adjustable stroke shines when you need to synchronize multiple end positions across a line using shared spares, or trim a 75 mm extend down to 45 mm on site. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2. Because this SKU lacks the -S suffix, it cannot accept CMSG/DMSG/EMSG magnetic sensors. Even at 75 mm, always guide the rod to prevent side-load wear.
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 SGCJ250X75-30 FAQ
At 0.5 MPa it pushes 24543 N and pulls 23562 N. At 0.7 MPa it pushes 34360 N and pulls 32986 N. The theoretical maximum force is 5006 kgf at 1.0 MPa. It uses a 50 mm rod, M42x2.0 thread, and a 60 mm adjustable air cushion at each end.
The nominal 75 mm extend stroke is the maximum. The external adjuster lets you shorten the extend travel by up to 30 mm on site, giving a usable extend range of 45 to 75 mm. The retract end is fixed. This mechanism sets the end position and is not a load lock; use an external rod lock or pilot-operated check valve to hold a load.
