Airtac SGC Standard Cylinder SGC250X480S
The AirTAC Airtac SGC Standard Cylinder SGC250X480S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 480mm 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 SGC250X480S
Delivering massive thrust for heavy industrial tasks, this double-acting tie-rod cylinder generates a push force of 24543 N at 0.5 MPa. The SGC250X480S features a 250 mm bore, a 480 mm stroke, and a G1 air port. Four steel tie rods clamp the aluminum barrel to the front and rear covers, providing exceptional rigidity under high stress. A two-way piston seal maintains an internal oil reservoir to ensure long operational life.
Because this SKU includes the -S suffix, a built-in piston magnet enables direct mounting of CMSG, DMSG, or EMSG position switches. Note that TPU seals are not offered for the Ø250 bore; instead, NBR components handle the front-cover packing and buffer gasket. For practical sizing, plan for around 14726 N of real work at 0.5 MPa, which equates to lifting roughly 1251 kg vertically with a 2:1 safety margin.

Where the Airtac SGC Standard Cylinder SGC250X480S Is Used
Heavy Press Stamping
Drives large metal forming presses where the 34360 N push force at 0.7 MPa is required to bend thick steel plates.
Pallet Dispenser Actuation
Pushes heavy stacks of wooden pallets in automated distribution lines, utilizing the 480 mm stroke to clear the magazine.
Injection Mold Clamping
Secures large industrial molds by applying up to 5006 kgf of theoretical clamping force at the maximum 1.0 MPa pressure.
Is the Airtac SGC Standard Cylinder SGC250X480S the Right Cylinder?
Choosing this 250 mm bore means operating at the top end of the SGC range, as there is no larger standard size available in this series. If your application requires less force, stepping down to the 200 mm bore drops the 0.5 MPa push rating to 15708 N. The 480 mm stroke is well below the 1500 mm maximum, but at this extended length you should incorporate external guide rails to prevent rod bending and absorb side loads. The -S magnet on this unit allows seamless integration of CMSG, DMSG, or EMSG sensors for end-of-stroke detection.
Keep in mind that a standard double-acting cylinder will drift if air pressure is lost or the control valve is centered. The adjustable 60 mm air cushions at both ends only serve to decelerate the piston near the end of its travel; they do not function as a locking brake. To safely suspend a vertical load, 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 SGC250X480S FAQ
This 250 mm bore model uses a G1 air port and an M42x2.0 rod thread. It delivers a push force of 24543 N and a pull force of 23562 N at 0.5 MPa. At 0.7 MPa, the push is 34360 N and the pull is 32986 N. The theoretical maximum force is 5006 kgf at 1.0 MPa.
