Airtac SGC Standard Cylinder SGC250X35
The AirTAC Airtac SGC Standard Cylinder SGC250X35 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 35mm 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 SGC250X35
Delivering massive thrust in a compact 35 mm stroke, this double-acting single-rod actuator provides 24543 N of push force at 0.5 MPa. The Ø250 bore uses a G1 air port and an M42x2.0 piston rod, built on a genuine ISO 15552 mounting interface so it drops directly into existing large-bore fixtures. Four steel tie rods clamp the aluminium barrel to the covers for high rigidity, while the two-way piston seal maintains an internal oil reservoir for long service life.
Because this is a Ø250 bore, TPU seals are not available; instead, the front-cover packing and buffer gasket use NBR (with a Viton H option for 0-150 C high-temperature environments). Plan for roughly 14726 N of real work at 0.5 MPa, which safely lifts about 1251 kg vertically with a 2:1 margin. Note that this specific SKU lacks the -S magnet and therefore cannot accept CMSG, DMSG, or EMSG position switches.

Where the Airtac SGC Standard Cylinder SGC250X35 Is Used
Heavy-Duty Stamping
Generates 24543 N of push at 0.5 MPa for short-stroke metal forming and riveting operations in automotive assembly lines.
Hydraulic Press Backup
Acts as a pneumatic override or hold-down in heavy presses, utilizing the 60 mm adjustable air cushions to absorb severe end-of-stroke impacts.
Injection Mould Clamping
Secures large industrial moulds with a 1251 kg safe vertical lift capacity, leveraging the rigid four-tie-rod construction against high forces.
Is the Airtac SGC Standard Cylinder SGC250X35 the Right Cylinder?
When sizing this actuator, consider the neighbouring bores: the Ø200 offers 15708 N push at 0.5 MPa if your load is lighter, while the Ø250 maxes out the SGC range at 24543 N. If you need position feedback, select the -S magnet variant instead of this base model to enable CMSG, DMSG, or EMSG sensors. For vertical or suspended loads, remember that a plain cylinder drifts when air is lost or the valve is centered; the adjustable air cushion only decelerates the piston near stroke end and acts as no lock, so specify an external rod lock or pilot-operated check valve for safety.
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 SGC250X35 FAQ
The SGC250X35 delivers 24543 N push and 23562 N pull at 0.5 MPa, and 34360 N push and 32986 N pull at 0.7 MPa. The theoretical maximum force is 5006 kgf at 1.0 MPa. It features a G1 air port, an M42x2.0 rod thread, and a 60 mm adjustable air cushion at both ends.
No, this specific SKU does not include a magnet. You must select the -S variant (SGC250X35-S) to use CMSG, DMSG, or EMSG magnetic switches. The standard ISO 15552 mounting interface and four steel tie rods remain identical across both versions.
