About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X220
The AirTAC SC125X220 is a robust 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 piston rod and M27x2 knuckle thread, this cylinder is built for demanding industrial tasks requiring high force output.
This 220 mm stroke model stays within the standard stroke range for the 125 mm bore, ensuring quick availability. The adjustable air cushion at both ends, with a 28 mm cushion length, effectively decelerates the piston to minimize end-of-stroke impact, protecting your equipment during high-cycle operations.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X220 Is Used
Heavy Machinery Actuation
Provides the high force for lifting and positioning heavy implements on agricultural and construction equipment, leveraging its 11045 N max thrust.
Palletizing Systems
Operates heavy-duty palletizers and depalletizers, moving stacked goods with consistent force and the durability of a tie-rod cylinder.
Large Component Clamping
Secures large weldments and fabrications in heavy manufacturing jigs, using its 32 mm rod for stable, high-force clamping.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X220 the Right Cylinder?
Selecting the SC125X220 means matching its 125 mm bore to your force requirements. If 6136 N at 0.5 MPa is slightly above your needs, stepping down to the SC100 bore provides 3927 N. For applications with significant side loads, especially on this 220 mm stroke, an external guide rod assembly is recommended to prevent bending stress on the 32 mm rod and premature seal wear. When replacing, ensure a 5-point match: 125 mm bore, 220 mm stroke, PT1/2 port thread, basic mount, and no 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 SC125X220 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 at 1.0 MPa is 1251 kgf.
No, the SC is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. It matches other AirTAC SC tie-rod cylinders of the same bore, stroke, port, and mounting type.
