About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X20
The AirTAC SC160X20 is a robust double-acting tie-rod cylinder delivering substantial force in a compact 20 mm stroke. With a 160 mm bore, it generates 10053 N pushing and 9425 N pulling at 0.5 MPa, making it ideal for short-throw clamping, pressing, or ejecting tasks.
This model features a 40 mm diameter piston rod with M36x2 male threads and a PT3/4 pneumatic port. The total extended body length is approximately 259 mm, and the adjustable air cushion (29 mm length) decelerates the piston smoothly at end-of-stroke to reduce impact noise and wear.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X20 Is Used
Heavy-Duty Clamping
Short 20 mm stroke with 10053 N force at 0.5 MPa securely clamps large weldments or castings during machining or assembly.
Die Cushion / Ejector
Provides a powerful, controlled ejection stroke in stamping dies or injection molds, resisting high stripping forces.
Press-Fit Assembly
Installs bearings, bushings, or pins into heavy housings with a controlled 20 mm press stroke and 18095 N max force at 0.9 MPa.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X20 the Right Cylinder?
Select the SC160X20 for high-force, short-stroke applications where a 160 mm bore is necessary. If your force requirement is lower, stepping down to the SC125 bore (6136 N push at 0.5 MPa) can reduce air consumption and physical size. For longer strokes up to 1500 mm, the SC160 series remains the correct choice.
When replacing an existing cylinder, ensure a 5-point match: 160 mm bore, 20 mm stroke, PT3/4 port thread, basic mounting (no bracket), and no magnet. This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
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 SC160X20 FAQ
At 0.5 MPa operating pressure, the SC160X20 produces 10053 N of push force on extension and 9425 N of pull force on retraction. The maximum theoretical force at 1.0 MPa is 2050 kgf.
This specific model code SC160X20 does not include the -S magnet option. To use CMSG, DMSG, or EMSG solid-state or reed sensors, order the SC160X20-S variant, which has a built-in magnet band on the piston.
