Airtac SGC Standard Cylinder SGC250X185
The AirTAC Airtac SGC Standard Cylinder SGC250X185 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 185mm 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 SGC Standard Cylinder SGC250X185
Generating massive thrust for heavy industry, this double-acting ISO 15552 tie-rod cylinder pushes with 24543 N and pulls with 23562 N at 0.5 MPa. Four steel tie rods clamp the aluminum barrel to the covers for extreme rigidity under high stress, while the two-way piston seal maintains an internal oil reservoir for long service life. Because it is dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures.
Featuring a 250 mm bore, a 50 mm piston rod, and a G1 air port, this unit operates at 30-500 mm/s with 60 mm adjustable air cushions at both ends. Plan for roughly 14726 N of real work at 0.5 MPa, which lifts about 1251 kg vertically with a 2:1 safety margin. Note that this SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. Also, TPU seals are unavailable for this bore; the front-cover packing and buffer gasket are NBR, with a Viton H option for 0-150 C environments.

Where the Airtac SGC Standard Cylinder SGC250X185 Is Used
Heavy Stamping Press
Drives large dies in an automotive stamping line, utilizing the 34360 N push force at 0.7 MPa to form thick steel plates reliably.
Injection Mold Clamping
Secures heavy industrial molds during plastic injection cycles, using the rigid tie-rod construction to resist deflection under high clamping loads.
Palletizer Actuator
Lifts and positions fully loaded shipping pallets weighing up to 1251 kg vertically, operating safely within a 2:1 calculated margin.
Is the Airtac SGC Standard Cylinder SGC250X185 the Right Cylinder?
When sizing this 250 mm bore model, compare its 24543 N push force at 0.5 MPa against the smaller 200 mm bore, which provides 15708 N. As this is the largest standard SGC bore, moving beyond 24543 N requires parallel cylinders or custom setups. If your application needs position sensing, select the -S magnet variant to enable CMSG, DMSG, or EMSG switches.
The 185 mm stroke falls well under the 500 mm side-load threshold, but heavy masses still require careful guide alignment. Remember that a standard cylinder drifts when air is lost or a valve centers; the air cushions only decelerate the piston near the stroke ends and do not act as a lock. To hold a load securely, 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 SGC Standard Cylinder SGC250X185 FAQ
The 250 mm bore yields a push of 24543 N and a pull of 23562 N at 0.5 MPa, or 34360 N push and 32986 N pull at 0.7 MPa, with a theoretical max of 5006 kgf at 1.0 MPa. It features a G1 port, a 50 mm rod, M42x2.0 rod thread, and 60 mm adjustable air cushions at both ends.
This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. Mechanically, its ISO 15552 mounting interface makes it dimensionally interchangeable with standard large-bore fixtures, and the four steel tie rods provide high structural rigidity.
