Airtac SGC Standard Cylinder SGC250X600STC
The AirTAC Airtac SGC Standard Cylinder SGC250X600STC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 600mm 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 SGC250X600STC
Delivering 24543 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder handles the heaviest pneumatic automation tasks. Four steel tie rods clamp the aluminum barrel to the covers for extreme structural rigidity, while a two-way piston seal maintains an internal oil reservoir for long component life. Because it is dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures without custom bracketry.
For practical sizing, plan for about 14726 N of real work at 0.5 MPa, or roughly 1251 kg lifted vertically with a 2:1 safety margin. The 250 mm bore uses a G1 air port and an M42x2.0 rod thread. Note that TPU seals are not offered at this bore size; the front-cover packing and buffer gasket are NBR, with a Viton H option available for 0-150 C high-temperature environments. The built-in magnet (-S) directly supports CMSG, DMSG, and EMSG position switches.

Where the Airtac SGC Standard Cylinder SGC250X600STC Is Used
Heavy Pallet Lifting
Raises loaded pallets weighing up to 1251 kg in automated distribution hubs, utilizing the 24543 N push force and 600 mm stroke to elevate goods between conveyor tiers.
Stamping Press Feed
Pushes heavy-gauge steel blanks into large mechanical presses, relying on the rigid four-tie-rod construction to absorb high-impact insertion forces without barrel flex.
Automated Storage Retrieval
Actuates 600 mm extraction arms in automated storage and retrieval systems, using the TC trunnion mount to pivot heavy tooling trays out of high-density shelving.
Is the Airtac SGC Standard Cylinder SGC250X600STC the Right Cylinder?
When sizing this 600 mm stroke unit, verify if the smaller 200 mm bore (providing 15708 N push at 0.5 MPa) is sufficient, as the 250 mm bore is the largest available in the SGC family. At a 600 mm extension, large-bore rods are highly susceptible to side-load bending; you must use an external guide or rod-end support to prevent premature seal failure and cylinder damage. The included TC trunnion mount helps manage pivotal loads, but remember that a standard cylinder cannot hold a load if air pressure drops—the end-of-stroke air cushion only decelerates the piston and acts as neither a lock nor a brake. For suspended or vertical loads, install an external rod lock or a pilot-operated check valve.
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 SGC250X600STC FAQ
This 250 mm bore cylinder features a G1 air port and an M42x2.0 rod thread. The thrust output is 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, the adjustable air cushions at both ends only decelerate the piston near the stroke limits and do not function as a locking brake. If air pressure is lost or the valve is centered, the piston will drift. For vertical or suspended loads, you must install an external rod lock or a pilot-operated check valve.
