Airtac SGC Standard Cylinder SGC250X300TC
The AirTAC Airtac SGC Standard Cylinder SGC250X300TC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 300mm 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 SGC250X300TC
Generating massive thrust for heavy industrial machinery, this double-acting 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, providing the high rigidity needed to handle large-bore forces without flexing. A two-way piston seal maintains an internal oil reservoir for continuous lubrication and extended service life.
Dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures. Because this is a 250 mm bore, TPU seals are not available; instead, NBR components handle the front-cover packing and buffer gasket. For practical sizing, plan for about 14726 N of real work at 0.5 MPa, which safely lifts roughly 1251 kg vertically with a 2:1 margin. The G1 air port supplies the volume required for the 30-500 mm/s speed range.

Where the Airtac SGC Standard Cylinder SGC250X300TC Is Used
Heavy Press Ejection
Provides the robust 24543 N push force needed to eject thick steel blanks from a 500-ton mechanical press.
Foundry Mold Clamping
Secures heavy sand casting molds under high vibration, utilizing the rigid four-tie-rod construction to prevent deflection.
Palletizer Lift Arm
Drives a pivoting lift carriage via the TC trunnion mount, moving 1200 kg unit loads vertically at controlled speeds.
Is the Airtac SGC Standard Cylinder SGC250X300TC the Right Cylinder?
When sizing this 300 mm stroke model, compare it against the adjacent bores: the 200 mm option yields 15708 N push at 0.5 MPa, while the 250 mm bore shown here provides 24543 N. If you need even more power, note that 250 mm is the largest standard SGC bore available. The integrated TC trunnion mount is ideal for pivoting loads, but remember that a plain cylinder drifts when air is lost or a valve is centered. The adjustable 60 mm air cushions only decelerate the piston near stroke ends; to hold a suspended load safely, install an external rod lock or a pilot-operated check valve. Since this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches.
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 SGC250X300TC FAQ
This 250 mm bore cylinder features a G1 air port and an M42x2.0 rod thread. It 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.
No, this specific SKU does not include a magnet. You must select the -S variant to use CMSG, DMSG, or EMSG magnetic switches. The TC trunnion mount follows the ISO 15552 mounting interface, ensuring compatibility with standard large-bore accessories.
