Airtac SGC Standard Cylinder SGC250X700S
The AirTAC Airtac SGC Standard Cylinder SGC250X700S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 700mm 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 SGC250X700S
Delivering 24543 N of push force at 0.5 MPa, this double-acting large-bore tie-rod cylinder handles heavy-duty automation. Four steel tie rods clamp the aluminium barrel to the covers for high structural rigidity. The Ø250 bore uses NBR front-cover packing and buffer gaskets, as TPU seals are not offered at this size, while a Viton H option extends operating temperatures to 0-150 C. A built-in piston magnet supports CMSG, DMSG, and EMSG position switches.
Featuring a 700 mm stroke and a G1 air port, the design is dimensionally interchangeable per the ISO 15552 mounting interface. The two-way piston seal maintains an internal oil reservoir for long service life. Plan for about 14726 N of real work at 0.5 MPa, which lifts roughly 1251 kg vertically with a 2:1 safety margin.

Where the Airtac SGC Standard Cylinder SGC250X700S Is Used
Press Stamping
Provides 34360 N push at 0.7 MPa for forming heavy-gauge metal components in automated stamping presses.
Pallet Handling
Lifts roughly 1251 kg vertically with a 2:1 margin, ideal for actuating massive industrial pallet rotators.
Injection Moulding
Clamps large mould halves securely using the rigid four-tie-rod construction during heavy plastic injection cycles.
Is the Airtac SGC Standard Cylinder SGC250X700S the Right Cylinder?
When sizing this 250 mm bore model, the smaller 200 mm bore yields 15708 N push at 0.5 MPa, while no larger SGC bore exists for higher demands. Because the 700 mm stroke is substantial, add external guide rails to prevent rod bending under side loads. The included -S magnet enables CMSG, DMSG, and EMSG sensors for end-position detection. Remember that exhausting air or centring the valve causes the piston to drift; the adjustable 60 mm air cushions only decelerate near stroke end. Use an external rod lock or pilot-operated check valve to hold a suspended load safely.
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 SGC250X700S FAQ
This model features 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, with a theoretical maximum of 5006 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, fitting standard LB, FA, and TC mounts. It does not hold position on air loss; the cushions only decelerate the piston, so add an external rod lock for suspended loads.
