About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1400
The AirTAC SC125X1400 is a double-acting tie-rod 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 32 mm diameter piston rod and a 28 mm adjustable air cushion, this 125 mm bore actuator is engineered for heavy industrial linear motion tasks requiring a long 1400 mm working stroke.
This model features a PT1/2 port and an M27x2 rod thread, with a compact body length A of 203 mm. As part of the ISO 6430 class for big bores, it operates within a speed range of 30-500 mm/s and a standard temperature range of -20 to +70 °C using TPU seals.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1400 Is Used
Heavy Material Handling
Pushes and positions pallets or heavy jigs on conveyor transfer stations, leveraging the 6136 N force at standard plant pressure.
Large Part Clamping
Applies high clamping force for welding fixtures or machining centers on oversized workpieces, using the long 1400 mm stroke for deep access.
Agricultural Machinery Actuation
Operates chutes, gates, or hopper doors on farming equipment, where the tie-rod design withstands dusty environments and heavy cyclical loads.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1400 the Right Cylinder?
Select the SC125 bore when your application needs the 6136 N force class at 0.5 MPa; if you require a higher force, step up to the SC160 which provides 10053 N, or down to the SC100 for 3927 N. For this 1400 mm stroke, side-load management is critical—always use an external guide rail or rod-alignment coupler to prevent bending stress on the 32 mm rod, as long unsupported strokes are vulnerable to side loads.
For a direct replacement, match five key points: 125 mm bore, 1400 mm stroke, PT1/2 port thread, the specific mounting accessory (this basic model has none), and the magnet option (this model has no built-in magnet).
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 SC125X1400 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 force at 1.0 MPa is 1251 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder, so it is not dimensionally interchangeable. You must replace it with another AirTAC SC125 tie-rod cylinder or a mechanically compatible equivalent matching the bore, stroke, PT port, and mounting.
