Airtac SGC Standard Cylinder SGC250X175
The AirTAC Airtac SGC Standard Cylinder SGC250X175 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 175mm 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 SGC250X175
Delivering massive thrust for heavy industry, this double-acting ISO 15552 tie-rod cylinder generates 24543 N of push force at 0.5 MPa. Four steel tie rods clamp the aluminium barrel to the covers, ensuring high structural rigidity when moving substantial payloads. Because this is a Ø250 bore, TPU seals are not offered; instead, the front-cover packing and buffer gasket utilise NBR, with a Viton H option available for 0-150 C high-temperature environments.
For practical sizing, 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. The unit features a G1 air port, an M42x2.0 rod-end thread, and a 60 mm adjustable air cushion at both ends to decelerate the piston smoothly. Note that this specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG magnetic switches.

Where the Airtac SGC Standard Cylinder SGC250X175 Is Used
Heavy Press Stamping
Drives large forming dies in automotive stamping presses where 24543 N of push force at 0.5 MPa is required to shape thick steel plates.
Palletizer Elevation
Lifts heavy unitized freight on automated palletizing lines, safely managing vertical loads of up to 1251 kg with a 2:1 safety margin.
Injection Mold Clamping
Secures heavy industrial molds during injection molding processes, utilizing the rigid four tie-rod construction to resist deflection under high clamping forces.
Is the Airtac SGC Standard Cylinder SGC250X175 the Right Cylinder?
When sizing this 250 mm bore actuator, the adjacent option downward is the Ø200 model, which provides 15708 N of push at 0.5 MPa; the SGC250 is the largest available in this series, so no larger standard bore exists for higher demands. Because this SKU is not equipped with the -S magnet, position sensing via CMSG, DMSG, or EMSG switches is not possible without upgrading to the magnet variant. For mounting flexibility, the standardized ISO 15552 interface allows seamless integration with LB foot, FA/FB flange, or TC/FTC trunnion hardware.
Keep in mind that a standard pneumatic cylinder cannot hold a load if air pressure is lost or the valve is centered, as the piston will drift and the end cushions only serve to decelerate motion near stroke completion. To suspend a load safely, incorporate an external rod lock or a pilot-operated check valve into your circuit design.
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 SGC250X175 FAQ
This Ø250 mm bore model features a G1 air port, an M42x2.0 rod thread, and a 60 mm adjustable air cushion. 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.
This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. Dimensionally, it is interchangeable per the ISO 15552 mounting interface, allowing it to drop directly into existing large-bore ISO 15552 foot, flange, or trunnion accessories.
