Airtac SGC Standard Cylinder SGC250X750S
The AirTAC Airtac SGC Standard Cylinder SGC250X750S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 750mm 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 SGC250X750S
Delivering massive thrust, 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 high structural rigidity under heavy loads, while the two-way piston seal maintains an internal oil reservoir for long mechanical life. Because it carries the -S suffix, a built-in piston magnet allows direct mounting of CMSG, DMSG, or EMSG switches for position sensing.
As a Ø250 bore, the front-cover packing and buffer gasket utilize NBR material rather than TPU, with a Viton H option available for 0-150 C high-temperature environments. It features a G1 air port, an M42x2.0 rod thread, and 60 mm adjustable air cushions at both ends. Plan for about 14726 N of real work at 0.5 MPa, which safely lifts roughly 1251 kg vertically with a 2:1 margin.

Where the Airtac SGC Standard Cylinder SGC250X750S Is Used
Heavy Stamp Press Ejection
Provides the robust 24543 N push force needed to eject thick steel blanks from a 500-ton stamping press over the 750 mm travel distance.
Palletizer Transfer Arm
Utilizes the built-in -S magnet with DMSG sensors to track the full 750 mm stroke while shifting heavy unit loads onto outbound conveyor lines.
Large Injection Mold Clamping
Leverages the rigid four-tie-rod construction and NBR seals to maintain steady clamping pressure on large resin injection molds during the curing cycle.
Is the Airtac SGC Standard Cylinder SGC250X750S the Right Cylinder?
When sizing this 750 mm stroke unit, consider the neighboring SGC bore: the 200 mm class yields 15708 N push at 0.5 MPa, while the 250 mm bore is the largest available in the SGC family, topping out at 34360 N push at 0.7 MPa. If your application requires holding a suspended load vertically, note that exhausting air or centering the valve will cause the piston to drift; the end cushions only decelerate the stroke and do not act as a brake. An external rod lock or pilot-operated check valve is required for secure load holding.
Due to the 750 mm stroke length on a large-bore piston, side-load forces can induce rod bending. Ensure adequate external guide mechanisms and rigid rod-end support to prevent premature seal wear and cylinder damage.
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 SGC250X750S FAQ
This Ø250 mm bore cylinder features a G1 air port and an M42x2.0 rod thread. The thrust ratings are 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 force of 5006 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, so it drops directly into standard large-bore ISO fixtures and mounting hardware like TC trunnions or CA clevis. The -S suffix denotes a built-in piston magnet, enabling the use of CMSG, DMSG, or EMSG electronic or reed switches along the barrel.
