About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X55
The AirTAC SC160X55 is a double-acting tie-rod cylinder delivering substantial force in a compact 55 mm stroke. At 0.5 MPa it generates 10053 N pushing and 9425 N pulling, while at the maximum operating pressure of 0.9 MPa thrust rises to 18095 N—ideal for short-cycle clamping, pressing, or lifting where space is limited.
This 160 mm bore model uses a 40 mm diameter piston rod with an M36x2 knuckle thread and a 29 mm adjustable air cushion to decelerate the load smoothly. The body length A is 239 mm, giving a total extended length of approximately 294 mm. Ports are PT3/4, and the standard TPU seals suit operating temperatures from -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X55 Is Used
Short-Stroke Pressing
The 55 mm stroke and 18 kN max force make this cylinder suitable for pneumatic pressing, staking, or crimping operations where the working distance is minimal but force demand is high.
Clamping & Fixturing
Delivers rapid, repeatable clamping force for machining fixtures, welding jigs, and assembly stations. The adjustable cushion protects tooling from impact at the end of each short cycle.
Heavy-Duty Ejectors
Ideal for ejecting heavy parts from moulds or dies. The 40 mm rod resists buckling under the high push forces required to release stubborn components.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X55 the Right Cylinder?
Choose the SC160X55 when your application needs high force in a short stroke—the 160 mm bore provides over 10 kN at just 0.5 MPa. If you require even greater force, the SC200 bore delivers 15708 N at the same pressure. For lighter loads where a smaller cylinder saves air and space, the SC125 bore offers 6136 N push at 0.5 MPa.
When replacing an existing cylinder, match five points: 160 mm bore, 55 mm stroke, PT3/4 port thread, basic mounting (no bracket), and confirm whether a magnet (-S suffix) is needed for sensors. The SC is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders—only replace with another AirTAC SC of the same specifications.
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 SC160X55 FAQ
At 0.5 MPa the push force is 10053 N and pull force is 9425 N. At 0.7 MPa push rises to 14074 N, and at the maximum operating pressure of 0.9 MPa it reaches 18095 N. The theoretical maximum at 1.0 MPa is 2050 kgf (approximately 20100 N).
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder, so mounting dimensions and end-cap profiles differ. You must replace it with another AirTAC SC160 tie-rod cylinder matching the bore, stroke, PT3/4 port, and mounting style.
