About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X130
The SC125X130 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 125 mm bore with a 130 mm stroke. At 0.5 MPa it generates 6136 N pushing force, scaling to 11045 N at 0.9 MPa, making it a capable actuator for medium-to-heavy industrial tasks. The 32 mm diameter piston rod and 28 mm adjustable air cushion help manage end-of-stroke deceleration.
This model uses the standard PT1/2 port thread and TPU seals for a -20 to +70 °C operating range. The body length A is 203 mm, giving a total extended length of approximately 333 mm. As a genuine AirTAC big-bore cylinder, it meets the ISO 6430 class dimensional envelope for 125 mm tie-rod cylinders.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X130 Is Used
Conveyor Diverters
The 6136 N push force at 0.5 MPa easily actuates heavy-duty diverter gates and sortation arms on wide conveyor lines, handling product flows up to 625 kgf.
Press & Clamping Fixtures
Delivers up to 11045 N at 0.9 MPa for pneumatic toggle clamps and assembly presses. The 130 mm stroke provides ample clearance for part loading and ejection.
Material Handling Lifts
Suitable for scissor-lift tables and tilt mechanisms. The 32 mm rod and tie-rod construction handle the structural demands of guided vertical lifting applications.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X130 the Right Cylinder?
For applications needing more force, stepping up to the SC160 (10053 N push at 0.5 MPa) provides a significant boost. If 6136 N is sufficient but space is tight, the SC100 (3927 N at 0.5 MPa) offers a smaller footprint. The 130 mm stroke is well within the 1500 mm maximum standard stroke for this bore.
When replacing an existing cylinder, match five points: 125 mm bore, 130 mm stroke, PT1/2 port thread, any mounting accessory (this is a basic body, so order F-SC125LB/FA/FB/CA/CB/TC separately if needed), and the magnet option (this model has no built-in magnet). For strokes over 300 mm, an external guide or guided cylinder is recommended to protect the rod from side-load bending.
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 SC125X130 FAQ
The theoretical pushing force is 6136 N at 0.5 MPa, 8590 N at 0.7 MPa, and 11045 N at the maximum operating pressure of 0.9 MPa. The pulling force on the retract stroke is 5734 N at 0.5 MPa due to the 32 mm rod reducing the piston area.
No. The SC series is a tie-rod cylinder, not an ISO 15552 profile cylinder. The SC125 is an ISO 6430 class big-bore cylinder, and its body length is shorter than an equivalent ISO 15552 unit. For a direct replacement, match another AirTAC SC125 tie-rod cylinder with the same 130 mm stroke, PT1/2 ports, and basic mounting configuration.
