Airtac SGC Standard Cylinder SGC250X75TC
The AirTAC Airtac SGC Standard Cylinder SGC250X75TC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 75mm 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 SGC250X75TC
Delivering 24543 N of push force at 0.5 MPa, this double-acting large-bore ISO 15552 tie-rod cylinder handles massive actuation tasks. Four steel tie rods clamp the aluminium barrel to the covers for high structural rigidity, while the two-way piston seal maintains an internal oil reservoir for long service life. Plan for about 14726 N of real work, which safely lifts roughly 1251 kg vertically with a 2:1 margin.
The Ø250 bore uses a G1 air port, an M42x2.0 rod thread, and a 60 mm adjustable air cushion at both ends. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches. Note that TPU seals are unavailable for this bore size; the front-cover packing and buffer gasket are NBR, with a Viton H option for 0-150 C high-temperature environments.

Where the Airtac SGC Standard Cylinder SGC250X75TC Is Used
Heavy Press Stamping
Drives large metal forming presses requiring 24543 N of push force at 0.5 MPa to deform thick steel plates.
Pallet Lift Gates
Actuates robust industrial lift gates, easily managing vertical loads up to 1251 kg with a safe 2:1 margin.
Injection Mold Clamping
Secures heavy injection molding halves using the rigid four-tie-rod build and 34360 N thrust at 0.7 MPa.
Is the Airtac SGC Standard Cylinder SGC250X75TC the Right Cylinder?
This 250 mm bore sits at the top of the SGC range, so if 24543 N at 0.5 MPa is excessive, step down to the 200 mm bore (15708 N push). There is no larger standard SGC option for higher demands. The TC trunnion mount utilizes the standardized ISO 15552 mounting interface, allowing seamless integration with existing large-bore fixtures. Since this model has no -S suffix, adding magnetic sensors requires upgrading to the magnet-equipped variant.
The 75 mm stroke keeps side-load risks minimal, but always verify rigid guidance on heavy loads. Remember that exhausting air or centering the valve causes the piston to drift; the air cushion only decelerates the stroke near the end cap and does not function as a brake. Install an external rod lock or pilot-operated check valve if you need 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 SGC250X75TC FAQ
The SGC250X75TC generates 24543 N push and 23562 N pull at 0.5 MPa, increasing to 34360 N push and 32986 N pull at 0.7 MPa. The theoretical maximum force is 5006 kgf at 1.0 MPa. It uses a G1 air port, an M42x2.0 rod thread, and features 60 mm adjustable air cushions.
No, because this specific SKU lacks the -S suffix, it does not have a piston magnet and cannot accept CMSG, DMSG, or EMSG switches. You must select the -S variant of the SGC series to enable magnetic sensing. The unit is dimensionally interchangeable per the ISO 15552 mounting interface.
