Airtac SGC Standard Cylinder SGC125X800S
The AirTAC Airtac SGC Standard Cylinder SGC125X800S is a genuine double acting ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 800mm 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 SGC125X800S
Delivering 6136 N of push force at 0.5 MPa, this double-acting ISO 15552 tie-rod cylinder is built for large-scale automation. Four steel tie rods clamp the aluminum barrel to the covers, providing the rigidity needed to handle heavy thrust without flexing. The two-way piston seal maintains an internal oil reservoir for continuous lubrication and extended service life.
Because this SKU includes the -S magnet, it supports CMSG, DMSG, and EMSG position switches for end-of-stroke detection. For practical sizing, 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 match the standard 125 mm bore specifications.

Where the Airtac SGC Standard Cylinder SGC125X800S Is Used
Pallet Transfer Diversion
Pushes heavy loaded pallets off a main conveyor line onto a secondary spur, utilizing the full 800 mm stroke to clear the path completely.
Automated Warehousing Pusher
Acts as a long-reach pusher in storage retrieval systems, shifting heavy totes from vertical shelving into the retrieval zone using 6136 N of thrust.
Large Press Ejection
Extracts formed metal parts from deep press beds, requiring the extended 800 mm reach to clear the machinery safely before the next cycle.
Is the Airtac SGC Standard Cylinder SGC125X800S the Right Cylinder?
When sizing this 125 mm bore actuator, compare your load against the 6136 N push figure at 0.5 MPa. If your application requires less force, stepping down is not possible within the SGC series as this is the smallest available bore; stepping up to the 160 mm bore yields 10053 N of push force. For vertical or heavy horizontal loads, remember that a standard cylinder drifts when air is removed or a valve is centered. The adjustable air cushion only decelerates the piston near the end of stroke, so install an external rod lock or pilot-operated check valve to hold the load safely.
At an 800 mm stroke, the 32 mm rod is highly susceptible to side-loading and bending forces. Always use an external guide rail or linear bearing to support the driven load and prevent rod damage. The -S magnet option ensures compatibility with electronic and reed sensors for precise positioning feedback.
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 SGC125X800S FAQ
This 125 mm bore cylinder features a G1/2 air port and delivers 6136 N push / 5734 N pull at 0.5 MPa, and 8590 N push / 8028 N pull at 0.7 MPa. The theoretical maximum force is 1251 kgf at 1.0 MPa.
