About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X60
The SC125X60 is a double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa, rising to 11045 N at the 0.9 MPa maximum operating pressure. With a 60 mm stroke and a robust 32 mm piston rod, this tie-rod cylinder is built for short, high-force clamping, pressing, or lifting tasks in heavy industrial settings.
This ISO 6430 class cylinder features an adjustable air cushion (28 mm length) at both ends to decelerate the piston smoothly, reducing impact noise and wear. The body length A is 203 mm, giving a compact extended length of approximately 263 mm. Ports are PT1/2 with an M27x2 rod thread, and the standard TPU seals suit ambient temperatures from -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X60 Is Used
Heavy-Duty Clamping
The 11045 N force at 0.9 MPa makes this cylinder ideal for powerful workpiece clamping in machining centers and welding fixtures, holding parts rigidly during high-vibration operations.
Material Stops and Gates
Deploy the SC125X60 as a short-stroke stop or diverter gate on heavy conveyor lines. Its 32 mm rod resists bending under the impact of pallets or large packages.
Press-Fit Assembly
Use the controlled 60 mm stroke for pressing bearings, bushings, or pins into housings. The adjustable cushion prevents hammering at the end of the press cycle, protecting tooling.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X60 the Right Cylinder?
For applications needing slightly less force in the same bore class, the 100 mm bore SC100 series provides 3927 N at 0.5 MPa. If your load demands the full 6136 N, the SC125 is the correct choice. This 60 mm stroke is a standard length, ensuring fast availability.
To replace an existing cylinder, match five points: 125 mm bore, 60 mm stroke, PT1/2 port thread, basic mounting (no brackets), and the absence of a magnet. The SC series is a tie-rod design 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 SC125X60 FAQ
At the standard 0.5 MPa operating pressure, 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.
This basic model (SC125X60) has no integral mounting brackets. For a pivoting application, order the SC125X60CA (rear single clevis) or SC125X60CB (rear double clevis) variant, which includes the corresponding F-SC125CA or F-SC125CB mounting accessory. You can also purchase the bracket separately and fit it to this cylinder.
