Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-40
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-40 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 SGCJ250X450-40
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 pneumatic port feeds the 50 mm piston rod to generate up to 5006 kgf of theoretical maximum thrust at 1.0 MPa.
The external -40 mm adjuster lets you shorten the extend stroke on-site from the 450 mm maximum down to 410 mm without changing the cylinder itself, while the retract end remains fixed. It handles a safe working load of about 14726 N, lifting roughly 1251 kg vertically with a 2:1 margin. Because this is a 250 mm bore, TPU seals are unavailable, but NBR packing is standard, and a Viton H option raises the operating temperature to 0-150 C. This non-magnet SKU cannot take a sensor; adding the -S variant enables CMSG/DMSG/EMSG switches.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-40 Is Used
Heavy Pallet Forming
Provides the raw 24543 N push force at 0.5 MPa needed to compress bulky pallet loads, using the 40 mm external adjuster to fine-tune the final end position for varying package heights.
Press Die Tuning
Clamps heavy industrial dies into exact position, where shortening the extend stroke on-site by up to 40 mm ensures precise contact without repositioning the entire fixture.
Bulk Lift Gate
Lifts roughly 1251 kg of bulk material vertically with a 2:1 safety margin, relying on the rigid tie-rod construction to maintain alignment under high side-loading conditions.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-40 the Right Cylinder?
When sizing this unit, the smaller 200 mm bore offers 15708 N of push at 0.5 MPa, whereas this 250 mm bore provides 24543 N, sitting at the top of the range for maximum output. The adjustable stroke is ideal for sharing a spare across stroke variants or fine-tuning the extend end position on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because the 450 mm stroke exceeds 500 mm, use a guide rail to prevent side-load damage. Note that this plain cylinder cannot hold a load without live air; the 60 mm adjustable air cushions only decelerate the piston. For a held load, install an external rod lock or a pilot-operated check valve.
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 SGCJ250X450-40 FAQ
This 250 mm bore cylinder features a G1 air port and an M42x2.0 rod thread. It delivers 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 450 mm stroke is the maximum length. The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, giving a usable extend range of 410-450 mm. The retract end is fixed, and this stop mechanism only sets the end position; it does not lock the load.
