Airtac SGC Standard Cylinder SGC125X450H
The AirTAC Airtac SGC Standard Cylinder SGC125X450H is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 450mm 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 SGC125X450H
Delivering 6136 N of push force at 0.5 MPa, this double-acting large-bore cylinder is built around the standardized ISO 15552 mounting interface, allowing it to drop directly into existing large-bore fixtures. The Viton H seal option extends the operating temperature range up to 150 C, making it suitable for hot environments where standard elastomers fail. Four steel tie rods clamp the aluminium barrel to the front and rear covers, providing the high rigidity needed to handle large-bore thrust, while a two-way piston seal maintains an internal oil reservoir for long service life.
With a 450 mm stroke and a G1/2 air port, operators should 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. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches. The adjustable 40 mm air cushions at both ends decelerate the piston near stroke end, but they do not function as a lock.

Where the Airtac SGC Standard Cylinder SGC125X450H Is Used
Hot Stamp Press Ejection
Ejects heavy forged parts from a heated stamping press, utilizing the Viton H seal to withstand ambient radiant heat up to 150 C while pushing with 6136 N.
Oven Door Automation
Opens and closes large industrial curing oven doors, where the 450 mm stroke provides the necessary travel and the high-temp seal resists degradation.
Molten Metal Skimming
Drives a skimming rake across a molten aluminum holding furnace, taking advantage of the tie-rod rigidity to maintain tool alignment in extreme heat.
Is the Airtac SGC Standard Cylinder SGC125X450H the Right Cylinder?
When sizing this actuator, compare its 6136 N push force at 0.5 MPa against your actual load requirements. If your application demands less force, stepping down is not possible within the SGC family as the 125 mm bore is the smallest available; conversely, the larger 160 mm bore provides 10053 N if higher thrust is needed. For this 450 mm stroke, ensure external guide rails are used to prevent rod bending under side loads, as long strokes are susceptible to deflection.
This base configuration lacks a magnet, meaning magnetic sensors cannot be used for end-of-stroke detection. If position feedback is required, select the -S variant. Furthermore, a standard double-acting cylinder will drift and lose its load if air pressure is lost or the valve is centred; to suspend a load safely, install an external rod lock or a pilot-operated check valve rather than relying on the air cushion.
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 SGC125X450H FAQ
This 125 mm bore cylinder features a G1/2 air port and a 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.
No, this specific SKU does not include the -S magnet option, so CMSG, DMSG, or EMSG switches cannot be used. You would need to specify the -S variant to enable magnetic sensing capabilities.
