Airtac SGC Standard Cylinder SGC250X160S
The AirTAC Airtac SGC Standard Cylinder SGC250X160S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 160mm 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 SGC250X160S
Delivering massive thrust for heavy industry, this double-acting ISO 15552 tie-rod cylinder generates 24543 N of push force and 23562 N of pull force at 0.5 MPa. Four steel tie rods clamp the aluminum barrel to the covers for extreme structural rigidity under high stress, while the two-way piston seal maintains an internal oil reservoir for long mechanical life. Plan for roughly 14726 N of real work at 0.5 MPa, which means it lifts about 1251 kg vertically with a 2:1 safety margin.
Because this SKU includes the -S piston magnet, it directly supports CMSG, DMSG, and EMSG position switches. The 250 mm bore uses a G1 air port and an M42x2.0 rod thread. Note that TPU seals are not offered on this largest bore; the front-cover packing and buffer gasket are NBR, with a Viton H option available for 0-150 C high-temperature environments.

Where the Airtac SGC Standard Cylinder SGC250X160S Is Used
Press Die Ejection
Provides the robust 24543 N push force required to eject heavy formed parts from large stamping presses, utilizing the G1 port for high-volume air delivery.
Palletizer Stopper Gate
Halts fully loaded industrial pallets on a conveyor line, safely absorbing the kinetic energy via the 60 mm adjustable air cushions at both ends.
Injection Mold Clamping
Secures heavy injection molding tooling halves, relying on the four steel tie rods to maintain barrel-to-cover alignment under extreme clamping loads.
Is the Airtac SGC Standard Cylinder SGC250X160S the Right Cylinder?
As the largest bore in the SGC family, there is no larger standard option; if 24543 N at 0.5 MPa is excessive, step down to the 200 mm bore which provides 15708 N. The 160 mm stroke keeps the side-load risk low, but always ensure rigid mounting using the LB foot, FA flange, or TC trunnion interfaces. The -S magnet pairs directly with CMSG, DMSG, or EMSG sensors for end-of-stroke confirmation.
Remember that the adjustable 60 mm air cushions only decelerate the piston near the end caps; they do not function as a brake. If the load must remain suspended when air pressure drops or the valve centers, you must add an external rod lock or a pilot-operated check valve to prevent drift.
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 SGC250X160S FAQ
The SGC250X160S 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 uses a G1 air port and an M42x2.0 rod thread.
No, the air cushions only decelerate the piston near the stroke ends and act as neither a lock nor a brake. Because it is double-acting, the piston will drift if air is lost or the valve is centered; use an external rod lock or pilot-operated check valve for suspended loads.
