Airtac SGC Standard Cylinder SGC125X1215
The AirTAC Airtac SGC Standard Cylinder SGC125X1215 is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 1215mm stroke, G1/2 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 SGC125X1215
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder handles substantial work over its 1215 mm travel. Because the stroke exceeds the 1500 mm standard catalog limit, it is produced as a non-standard made-to-order item. The aluminium barrel is clamped by four steel tie rods for high rigidity, and the two-way piston seal retains an oil reservoir to ensure long service life.
It uses the standardized ISO 15552 mounting interface, allowing it to drop directly into existing large-bore fixtures. Plan for about 3682 N of real work at 0.5 MPa, which equates to lifting roughly 313 kg vertically with a 2:1 safety margin. The bore dictates a G1/2 port and an M27x2.0 rod thread. This SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG position switches.

Where the Airtac SGC Standard Cylinder SGC125X1215 Is Used
Automated Pallet Transfer
Pushes heavy loaded pallets along a transfer line, utilizing the 6136 N push force to overcome friction over the long 1215 mm extension.
Vertical Material Lift
Raises platforms carrying components weighing up to 313 kg, relying on the rigid tie-rod construction to maintain stability during the extended vertical travel.
Large Press Ejection
Ejects finished stamped parts from large industrial presses, requiring the full 1215 mm reach to clear the press bed safely.
Is the Airtac SGC Standard Cylinder SGC125X1215 the Right Cylinder?
When sizing this actuator, consider the adjacent bores: stepping down is not an option as 125 mm is the smallest in the SGC family, while stepping up to the 160 mm bore yields 10053 N of push at 0.5 MPa. Given the extended 1215 mm travel, you must account for side loads and rod bending—using an external guide or rod-end support is critical to prevent premature wear.
Note that a standard SGC cylinder will drift if air is lost or the valve is centered; the adjustable 40 mm air cushions only decelerate the piston near the end of stroke and do not act as a lock. For suspended loads, install an external rod lock or a pilot-operated check valve. To add sensing, switch to the -S magnet variant.
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 SGC125X1215 FAQ
This 125 mm bore cylinder features a G1/2 port and an M27x2.0 rod thread. It generates 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push and 8028 N pull at 0.7 MPa, with a theoretical maximum force of 1251 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per the ISO 15552 mounting interface, so it drops into standard large-bore fixtures. However, because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG magnetic switches; you must select the -S variant for sensing.
