Airtac SGC Standard Cylinder SGC125X500TC
The AirTAC Airtac SGC Standard Cylinder SGC125X500TC is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 500mm 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 SGC125X500TC
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder handles heavy-duty linear motion. It features a genuine ISO 15552 mounting interface, dropping directly into existing large-bore fixtures and standard trunnion accessories without redesign. Four steel tie rods clamp the aluminum barrel to the covers, providing the high rigidity needed for substantial thrust, while the two-way piston seal maintains an internal oil reservoir for long service life.
Because this specific SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG magnetic switches. For position feedback, an external sensor setup is required. With a 500 mm stroke, 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 G1/2 port and M27x2.0 rod thread ensure robust pneumatic and mechanical connections across the 30-500 mm/s speed range.

Where the Airtac SGC Standard Cylinder SGC125X500TC Is Used
Pallet Diversion
Stops and diverts heavy wooden pallets along a high-throughput packaging line using 6136 N of thrust at 0.5 MPa over a 500 mm reach.
Automated Stacking
Lifts and positions steel totes weighing up to 313 kg vertically in a 2:1 margin automated storage and retrieval system.
Press Ejection
Clears finished stamped metal parts from a 125-ton press bed, utilizing the TC trunnion mount to articulate the ejection arm.
Is the Airtac SGC Standard Cylinder SGC125X500TC the Right Cylinder?
When sizing this 125 mm bore unit against its neighbors, stepping down is not an option within the SGC series as it is the smallest available bore. Stepping up to the 160 mm bore significantly increases capacity, raising the 0.5 MPa push force to 10053 N if your application demands more than the 6136 N provided here. The included TC trunnion mount suits pivoting articulations, but ensure your mechanical layout accommodates the 500 mm stroke length. At this extension, large-bore cylinders face increased rod-bending risks under side loads, so an external guide or rod-end support is strongly recommended to prevent premature seal wear. Remember that a standard double-acting cylinder drifts when air is lost or the valve is centered; the adjustable 40 mm air cushions only decelerate the piston near the stroke ends and do not function as a locking brake. To suspend a load safely, integrate 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 SGC125X500TC FAQ
The SGC125X500TC provides a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, the push force is 8590 N and the pull force is 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa. It features a G1/2 air port and an M27x2.0 piston rod thread.
No, this specific SKU does not include the -S magnet option, meaning it cannot accept CMSG, DMSG, or EMSG magnetic switches. You would need the -S variant for internal magnetic sensing. The cylinder does feature a genuine ISO 15552 mounting interface, allowing it to interchange with standard large-bore fixtures, and its tie-rod construction ensures high structural rigidity.
