Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-10
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-10 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 450mm 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 SGCJ250X450-10
Delivering 24543 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder handles heavy-duty positioning with ease. Four steel tie rods clamp the aluminum barrel to the covers, and the G1 air port feeds a 50 mm piston rod. Because it is an adjustable-stroke design, an external stop screw lets you shorten the extend stroke on-site by up to 10 mm, giving a usable range of 440-450 mm without changing the cylinder itself. The retract end remains fixed.
The bore is 250 mm, and the rod thread is M42x2.0 with 60 mm adjustable air cushions at both ends. It handles a safe working load of about 14726 N, which is roughly 1251 kg lifted vertically with a 2:1 margin. Note that TPU seals are not available on this 250 mm bore; it uses NBR seals, with a Viton H option for 0-150 C high-heat environments. This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-10 Is Used
Press Tonnage Adjustment
Fine-tune the 10 mm extend window on-site to set precise bottoming pressure for heavy stamping presses without swapping cylinders.
Heavy Pallet Positioning
Lifts roughly 1251 kg vertically with a 2:1 safety margin, ideal for shifting loaded pallets in automated distribution hubs.
Mold Clamping Alignment
Dial in the exact extend stop for large injection mold halves, ensuring perfect seating before the full 34360 N clamping force is applied.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-10 the Right Cylinder?
When sizing this unit, the neighboring 200 mm bore yields 15708 N push at 0.5 MPa, while this 250 mm bore tops out at 24543 N. If you need maximum thrust, the 250 mm bore provides 34360 N at 0.7 MPa. The adjustable-stroke feature is ideal when you need to fine-tune the extend end position on-site or want to share a single spare cylinder across multiple stroke variants. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 450 mm stroke exceeds 500 mm, you should use a guide to prevent side-load damage. Remember that a plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve to hold a load.
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 SGCJ250X450-10 FAQ
This 250 mm bore cylinder has a G1 air port and a 50 mm rod. It generates 24543 N push and 23562 N pull at 0.5 MPa, 34360 N push and 32986 N pull at 0.7 MPa, and a theoretical maximum of 5006 kgf at 1.0 MPa.
The nominal stroke is 450 mm, which is the maximum extend length. An external adjuster lets you shorten the extend stroke by up to 10 mm on-site, giving a usable range of 440-450 mm for fine-tuning the end position. The retract end is fixed, and this stop is not a load lock.
