Airtac SGC Standard Cylinder SGC250X800S
The AirTAC Airtac SGC Standard Cylinder SGC250X800S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 800mm 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 SGC250X800S
Delivering massive thrust for heavy-duty automation, this double-acting ISO 15552 tie-rod cylinder utilizes a 250 mm bore and an 800 mm stroke to generate 24543 N of push force at 0.5 MPa. Four steel tie rods clamp the aluminum barrel to the front and rear covers, providing the high rigidity required to handle large-bore pressures without flexing. The integrated -S piston magnet allows direct mounting of CMSG, DMSG, or EMSG switches for precise end-of-stroke detection.
Because of its substantial output, plan for about 14726 N of real work at 0.5 MPa, which equates to lifting roughly 1251 kg vertically with a 2:1 safety margin. This specific 250 mm bore uses a G1 air port and an M42x2.0 rod thread, with NBR seals on the front-cover packing and buffer gasket since TPU is not offered at this diameter. For environments exceeding 70 C, a Viton H high-temperature seal option extends the operating range up to 150 C.

Where the Airtac SGC Standard Cylinder SGC250X800S Is Used
Heavy Press Stamping
Provides the 34360 N push force at 0.7 MPa needed to form thick-gauge steel plates in automated metal stamping presses.
Pallet Dispenser
Uses the full 800 mm stroke to push empty pallets into high-speed packaging lines, easily handling loads up to 1251 kg.
Scissor Lift Actuation
Drives large material handling scissor lifts where the NBR seals and robust tie-rod construction endure high cyclic loads.
Is the Airtac SGC Standard Cylinder SGC250X800S the Right Cylinder?
Choosing this 800 mm stroke model requires careful attention to mechanical guidance; at this length, the 50 mm piston rod is susceptible to bending under side loads, so an external guide bearing must support the rod end to prevent premature seal failure. When sizing, note that stepping down to a 200 mm bore drops the 0.5 MPa push force to 15708 N, while the 250 mm bore represents the maximum standard SGC size available. The integrated -S magnet means you can easily fit CMSG, DMSG, or EMSG sensors without modifying the assembly.
Keep in mind that the adjustable 60 mm air cushions at both ends only decelerate the piston near the stroke limits; they do not function as a lock. If the air supply is lost or the valve is centered, the piston will drift, so you must incorporate an external rod lock or a pilot-operated check valve to safely hold a suspended load.
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 SGC250X800S FAQ
This 250 mm bore cylinder 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 force of 5006 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, allowing it to drop into existing large-bore fixtures using standard LB foot, FA flange, or TC trunnion mounts. The -S suffix indicates the built-in magnet required for CMSG, DMSG, or EMSG position sensors.
