Airtac SGC Standard Cylinder SGC250X650TC
The AirTAC Airtac SGC Standard Cylinder SGC250X650TC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 650mm 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 SGC250X650TC
Delivering massive thrust for heavy industry, this double-acting tie-rod cylinder pushes with 24543 N and pulls with 23562 N at 0.5 MPa. Four steel tie rods clamp the aluminum barrel to the covers for extreme structural rigidity under high stress. Because it is dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures without redesign. The two-way piston seal maintains an internal oil reservoir for continuous lubrication and extended service life.
Featuring a 250 mm bore, a 650 mm stroke, and a G1 air port, this unit uses an adjustable 60 mm air cushion at both ends to decelerate the heavy piston smoothly. Plan for about 14726 N of real work at 0.5 MPa, which translates to lifting roughly 1251 kg vertically with a 2:1 safety margin. Note that this SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG position switches. Additionally, the 250 mm bore uses NBR front-cover packing instead of TPU.

Where the Airtac SGC Standard Cylinder SGC250X650TC Is Used
Heavy Press Stamping
Drives large stamping dies in automotive lines where the 24543 N push force at 0.5 MPa easily forms thick steel plates.
Pallet Dispenser
Actuates heavy pallet dispensing gates in high-throughput logistics centers, utilizing the 650 mm stroke to clear tall load profiles.
Injection Mold Clamping
Secures large injection molding halves using the TC trunnion mount, relying on the rigid four-tie-rod construction to resist deflection.
Is the Airtac SGC Standard Cylinder SGC250X650TC the Right Cylinder?
When sizing this 250 mm bore unit against the SGC range, the next step down is the 200 mm bore delivering 15708 N push at 0.5 MPa, while this 250 mm model is the largest available in the series. For vertical or suspended loads, remember that a standard double-acting cylinder drifts when air is removed or the valve is centered; the air cushion only decelerates the stroke at the end caps and does not act as a brake. You must fit an external rod lock or pilot-operated check valve to hold a load safely. The TC trunnion mounting hardware is ideal for pivoting applications. Finally, the 650 mm stroke demands external guide rails to prevent rod bending and premature seal wear under side loads.
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 SGC250X650TC FAQ
This 250 mm bore cylinder features a G1 air port and an M42x2.0 rod thread. It generates 24543 N push and 23562 N pull at 0.5 MPa, increasing to 34360 N push and 32986 N pull at 0.7 MPa. The theoretical maximum force is 5006 kgf at 1.0 MPa.
This specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. Mechanically, it is dimensionally interchangeable per the ISO 15552 mounting interface, allowing you to reuse existing TC trunnion brackets and accessories from other ISO 15552 large-bore cylinders.
