About the Airtac SGC Standard Cylinder SGC250X600
Delivering massive thrust for heavy industrial tasks, this double-acting ISO 15552 tie-rod cylinder utilizes a 250 mm bore and a 600 mm stroke. It generates 24543 N of push force and 23562 N of pull force at 0.5 MPa, scaling up to a theoretical maximum of 5006 kgf at 1.0 MPa. Four steel tie rods clamp the aluminum barrel to the covers, providing the high rigidity needed to handle such large-bore pressures, while a two-way piston seal maintains an internal oil reservoir for long service life.
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. The unit features a G1 air port, an M42x2.0 rod thread, and 60 mm adjustable air cushions at both ends to decelerate the payload smoothly. Note that this specific SKU lacks the -S magnet, meaning it cannot support CMSG, DMSG, or EMSG magnetic switches; add the -S variant if position sensing is required. Additionally, being a 250 mm bore, the front-cover packing and buffer gasket use NBR rather than TPU, with a Viton H option available for 0-150 C high-temperature environments.

Where the Airtac SGC Standard Cylinder SGC250X600 Is Used
Heavy Stamp Press Ejection
Ejects large formed metal panels from 800-ton stamping presses, utilizing the 24543 N push force at 0.5 MPa to overcome die friction and strip heavy steel sheets reliably.
Automated Foundry Ladle Tilting
Actuates the rotation of massive molten metal ladles on automated pouring lines, where the 600 mm stroke provides the precise arc needed to control pour rates safely.
Large Injection Mold Separation
Drives the core pull mechanism on heavy-gauge plastic injection molds, using its 23562 N pull force at 0.5 MPa to extract deep-cavity tooling without hesitation.
Is the Airtac SGC Standard Cylinder SGC250X600 the Right Cylinder?
When sizing this 600 mm stroke unit, compare its 24543 N push force at 0.5 MPa against the neighboring 200 mm bore, which provides 15708 N. If 250 mm is insufficient, you are at the top of the SGC range and must explore alternative multi-cylinder circuits or external boosters. Because this model lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors, so you must integrate external limit switches or select the SGC250X600-S variant for magnetic positioning. Furthermore, a plain SGC cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered; the 60 mm air cushion only decelerates the piston near stroke end and acts purely as an end-of-stroke buffer, never as a brake. For suspended or vertical loads, always incorporate an external rod lock or a pilot-operated check valve.
With a 600 mm stroke on a large 250 mm bore, the extended piston rod is highly susceptible to bending under side loads. Ensure your mounting arrangement—whether LB foot, FA flange, CA clevis, or TC trunnion—provides rigid alignment, and use an external guide rail to support the payload, preventing rod damage and premature seal wear.
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 SGC250X600 FAQ
The SGC250X600 operates at 30-500 mm/s and features a G1 air port with an M42x2.0 rod thread. At 0.5 MPa it provides 24543 N of push force and 23562 N of pull force. At 0.7 MPa, push increases to 34360 N and pull to 32986 N. The theoretical maximum force is 5006 kgf at 1.0 MPa.
No, this SKU lacks the -S magnet, so it cannot support CMSG, DMSG, or EMSG magnetic switches. Additionally, the air cushions only decelerate the piston near the end of the stroke; they do not act as a brake. The cylinder will drift if air is lost, so you must use an external rod lock or pilot-operated check valve to hold vertical loads.
