About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X530
The AirTAC SC125X530 is a double-acting tie-rod cylinder delivering a substantial 6136 N of push force at 0.5 MPa, scaling up to 11045 N at the maximum operating pressure of 0.9 MPa. With a 125 mm bore and a 530 mm stroke, this model is built for heavy linear actuation tasks, featuring a robust 32 mm piston rod and an M27x2 rod thread for secure tooling attachment.
This cylinder includes a 28 mm adjustable air cushion at each end to decelerate high-inertia loads smoothly, protecting the end caps from impact damage. The body length A is 203 mm, giving a total extended length of approximately 733 mm. It uses standard PT1/2 ports and operates with filtered air within a -20 to +70 °C range, making it a reliable workhorse for demanding industrial environments.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X530 Is Used
Palletizer Pushers
Provides the high force needed to push heavy pallets or layers of bagged product into position on automated palletizing lines, handling the repetitive shock loads reliably.
Heavy-Duty Clamping
Delivers up to 11045 N of clamping force for large fabrication jigs and welding fixtures, securely holding heavy steel components during assembly or machining.
Balers and Compactors
Drives the compression ram in recycling balers, using its 125 mm bore to generate the necessary thrust for compacting cardboard, plastics, or textiles into dense bales.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X530 the Right Cylinder?
Select the SC125 bore when your application requires a push force in the 6136 N range at 0.5 MPa. If your load is lighter, stepping down to an SC100 bore provides 3927 N, reducing air consumption and physical footprint. For higher force requirements, the SC160 bore offers 10053 N at the same pressure.
For this 530 mm stroke, carefully evaluate side-loading conditions. Long, unsupported strokes on a single-rod cylinder can subject the rod bearing to high bending moments. To ensure long seal life, use an external guide system or a self-guided tooling plate to absorb any transverse forces. When replacing an existing cylinder, match five key points exactly: 125 mm bore, 530 mm stroke, PT1/2 port thread, the specific mounting accessory (if any), and the presence or absence of a magnetic piston.
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 SC125X530 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 increases to 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than a comparable ISO 15552 profile cylinder, so it is not dimensionally interchangeable. For replacement, match it to another AirTAC SC tie-rod cylinder with the same 125 mm bore, 530 mm stroke, and PT1/2 ports.
