About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X760S
The SC125X760S is a double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa. With a 125 mm bore and a 760 mm stroke, this model features a robust 32 mm piston rod and an adjustable air cushion of 28 mm to decelerate end-of-stroke impacts.
This tie-rod cylinder includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for reliable position feedback. The body length A is 203 mm, and the total extended length is approximately 963 mm. It uses standard PT ports (PT1/2) and operates with filtered air within a -20 to +70 °C range using default TPU seals.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X760S Is Used
Pallet Lifting & Stacking
The 6136 N push force at 0.5 MPa makes this cylinder ideal for lifting and stacking heavy pallets in automated warehouses, providing the necessary power for vertical material handling.
Heavy-Duty Clamping
Use the SC125X760S for powerful clamping fixtures in machining or welding cells. The built-in magnet enables sensor-based confirmation of clamp engagement for safety interlocks.
Product Pusher & Diverter
With its long 760 mm stroke and high force, this cylinder excels at diverting heavy packages or pushing large components off a main conveyor line onto a branch, with position sensing for accurate cycle control.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X760S the Right Cylinder?
Select the SC125 bore when your application requires push forces between roughly 6136 N and 11045 N. If your load is lighter, consider stepping down to the SC100 bore, which provides 3927 N at 0.5 MPa. For a 760 mm stroke, ensure the rod is protected from significant side loads; an external guide or a guided cylinder is recommended to prevent rod bearing damage and ensure long service life.
For a direct replacement, match five key points: the 125 mm bore, the 760 mm stroke, the PT1/2 port thread, the built-in magnet for sensors (-S), and the basic tie-rod mounting. The SC series is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC125X760S FAQ
At the standard operating pressure of 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 increases to 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
No. The SC125X760S is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered; the piston can drift. The adjustable air cushion only decelerates the piston at the stroke end to reduce impact and is not a locking or holding device. For load holding, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
