Airtac SGC Standard Cylinder SGC250X1500S
The AirTAC Airtac SGC Standard Cylinder SGC250X1500S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 1500mm 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 SGC250X1500S
Delivering massive thrust for heavy-duty automation, this double-acting tie-rod cylinder pushes with 24543 N and pulls with 23562 N at 0.5 MPa. Built to ISO 15552 mounting-interface dimensions, it drops directly into existing large-bore fixtures. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, while a two-way piston seal maintains an internal oil reservoir for long service life. Because this SKU includes the -S magnet, it supports CMSG, DMSG, and EMSG position switches.
On the Ø250 bore, the front-cover packing and buffer gasket are NBR (TPU is not offered at this size), and a Viton H option extends operation to 0-150 C. The G1 air port and M42x2.0 rod thread handle high flow and heavy loads. For practical sizing, plan for about 14726 N of real work at 0.5 MPa, which lifts roughly 1251 kg vertically with a 2:1 safety margin. Operating speed spans 30-500 mm/s, and adjustable 60 mm air cushions at both ends decelerate the piston near stroke end.

Where the Airtac SGC Standard Cylinder SGC250X1500S Is Used
Automotive Press Ejection
Ejects heavy formed panels from large stamping presses, utilizing the 34360 N push force at 0.7 MPa to overcome die friction and strip the metal part reliably.
Palletizer Push-Off
Actuates the 1500 mm sweep arm to push completed pallet loads onto a transfer chain, moving unit loads approaching the 1251 kg vertical lift threshold.
Injection Mold Separation
Provides the long 1500 mm reach and high pull force required to separate large industrial injection molding tooling halves for maintenance or part extraction.
Is the Airtac SGC Standard Cylinder SGC250X1500S the Right Cylinder?
Choosing this 1500 mm stroke requires careful attention to mechanical guidance. At full extension, large-bore rods are prone to bending under side loads, so an external guide or rod-end support is essential to prevent premature seal wear. If your application needs less force, the next size down is the Ø200 bore, which provides 15708 N of push force at 0.5 MPa; as the largest SGC option, there is no larger standard bore to step up to.
Remember that the adjustable air cushion only decelerates the piston near the end of travel and does not function as a brake. If air pressure drops or the valve is centered, the piston will drift, so you must add an external rod lock or pilot-operated check valve to hold a suspended load safely in place.
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 SGC250X1500S FAQ
This Ø250 bore model features a G1 air port and an M42x2.0 rod thread. The thrust ratings are 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 at 1.0 MPa is 5006 kgf.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, allowing you to use standard large-bore foot, flange, or trunnion brackets. Because this model includes the -S magnet, it directly supports CMSG, DMSG, and EMSG electronic and reed switches for end-of-stroke detection.
