Airtac SGC Standard Cylinder SGC250X50S
The AirTAC Airtac SGC Standard Cylinder SGC250X50S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 50mm 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 SGC250X50S
Delivering massive thrust for heavy industry, this double-acting tie-rod cylinder generates 24543 N of push force at 0.5 MPa. The robust design relies on four steel tie rods clamping the aluminum barrel to the covers, ensuring high rigidity under extreme loads. Because it is dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures. Equipped with a -S piston magnet, it supports CMSG, DMSG, and EMSG switches for position sensing.
For the Ø250 bore, TPU seals are unavailable; instead, the front-cover packing and buffer gasket utilize NBR, with a Viton H option available for 0-150 C high-temperature environments. The G1 air port accommodates high flow rates, while the 60 mm adjustable air cushions at both ends decelerate the piston smoothly. Plan for about 14726 N of real work at 0.5 MPa, which safely lifts roughly 1251 kg vertically with a 2:1 margin.

Where the Airtac SGC Standard Cylinder SGC250X50S Is Used
Heavy Stamp Press Feeder
Provides the 24543 N push at 0.5 MPa required to clamp heavy steel coils before a stamping press cycle.
Palletizer Lift Arm
Lifts roughly 1251 kg vertically with a 2:1 margin, ideal for rotating heavy pallet loads in automated distribution centers.
Injection Mold Lock
Utilizes its four steel tie rods and 34360 N push at 0.7 MPa to secure large injection molding halves during high-pressure resin injection.
Is the Airtac SGC Standard Cylinder SGC250X50S the Right Cylinder?
When sizing this 50 mm stroke actuator, verify your force requirements against its 23562 N pull at 0.5 MPa. If you need less power, there is no larger SGC bore above 250, but stepping down to the Ø200 bore drops the push force to 15708 N at 0.5 MPa. The integrated -S magnet allows seamless mounting of CMSG, DMSG, or EMSG sensors without external hardware.
Remember that a standard pneumatic cylinder cannot hold a load if air pressure drops or the valve is centered; the piston will drift, as the cushions only decelerate motion near stroke end. To suspend a load safely, install an external rod lock or a pilot-operated check valve. Given the substantial 50 mm piston rod and short 50 mm stroke, side-load stress is minimal compared to longer strokes, but proper alignment remains essential.
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 SGC250X50S FAQ
This model features a G1 air port and an M42x2.0 rod thread. It delivers 24543 N push and 23562 N pull at 0.5 MPa, 34360 N push and 32986 N pull at 0.7 MPa, with a theoretical maximum of 5006 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet compatible with CMSG, DMSG, and EMSG switches. Because it is a 250 mm bore, TPU seals are not offered; it uses NBR front-cover packing and buffer gaskets, with a Viton H option for 0-150 C high-temperature operations.
