About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X525S
The SC125X525S is a large-bore double-acting tie-rod cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at 0.9 MPa. Its 525 mm stroke suits long-travel material handling, pressing, and heavy-duty clamping operations.
This model features a built-in magnet (-S suffix), allowing CMSG/DMSG/EMSG reed or solid-state sensors to be mounted directly on the barrel for contactless position sensing. The 32 mm piston rod provides robust strength, and the adjustable air cushion (28 mm length) decelerates the load smoothly at stroke end. Operating pressure is 0.15-1.0 MPa with a PT1/2 port thread.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X525S Is Used
Pallet Transfer Systems
The 525 mm stroke and 6136 N push force at 0.5 MPa reliably shift heavy pallets between conveyor lines, with the built-in magnet enabling end-of-stroke confirmation via barrel-mounted sensors.
Heavy-Duty Clamping Fixtures
Delivering up to 11045 N at 0.9 MPa, this cylinder provides the high clamping force needed for welding jigs and machining fixtures on large structural components.
Industrial Compaction & Pressing
Ideal for waste compaction or panel pressing, the 32 mm rod and tie-rod construction handle the repetitive thrust loads, while the adjustable cushion protects the end-cap on each cycle.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X525S the Right Cylinder?
For applications needing more force, stepping up to the 160 mm bore provides 10053 N at 0.5 MPa; for a lighter, more compact solution, the 100 mm bore offers 3927 N. This 525 mm stroke is within the standard range for the 125 bore (max 1500 mm), but always check side-load conditions on long strokes. If the rod is exposed to lateral forces, consider an external guide or a guided cylinder to prevent rod bearing damage.
To ensure a correct replacement, match five key points: 125 mm bore, 525 mm stroke, PT1/2 port thread, the built-in magnet (-S) for sensor compatibility, and the basic mounting style. This is an AirTAC SC tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another SC of the same configuration.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac AIRTAC SC125-160 Standard Cylinder SC125X525S FAQ
At 0.5 MPa, the push force is 6136 N and the pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
Yes. The -S suffix in the model code indicates a built-in magnet on the piston, making this cylinder compatible with AirTAC CMSG, DMSG, or EMSG series sensors that clamp directly onto the tie-rod barrel.
