About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X70
The AirTAC SC160X70 is a double-acting tie-rod cylinder delivering substantial force in a compact 70 mm stroke format. At 0.5 MPa it generates 10053 N pushing and 9425 N pulling, while at the maximum operating pressure of 0.9 MPa the push force reaches 18095 N — ideal for heavy clamping, pressing, or lifting applications where a short, powerful linear motion is required.
This model features a 40 mm diameter piston rod with M36x2 threads and PT3/4 pneumatic ports. The adjustable air cushion (29 mm length) decelerates the piston smoothly at end-of-stroke, protecting the end caps and reducing noise. With a body length A of 239 mm, the total extended length is approximately 309 mm. Operating range is -20 to +70 °C with standard TPU seals.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X70 Is Used
Heavy Press Tool Actuation
The 18095 N push force at 0.9 MPa makes the SC160X70 ideal for short-stroke pressing, stamping, or die-cushion actuation in metal forming cells.
Pallet Lift & Transfer
Delivers over 10 kN at standard shop air to raise or shift heavy pallets in automated material handling stations where stroke length is limited.
Clamping & Fixturing
Use this cylinder for powerful, repeatable workpiece clamping on CNC machining centres or welding fixtures, holding parts rigidly during high-force operations.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X70 the Right Cylinder?
For applications needing slightly less force in the same stroke, consider stepping down to the SC125 bore (6136 N push at 0.5 MPa). If you require more force, the SC200 bore offers 15708 N at 0.5 MPa. The 40 mm rod on this SC160 provides excellent rigidity for the short 70 mm stroke, so side-load concerns are minimal here.
When replacing an existing cylinder, match five key points: 160 mm bore, 70 mm stroke, PT3/4 port thread, basic mounting (no accessory bracket), and confirm whether a magnet is needed (this model has none). The SC 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 SC160X70 FAQ
At 0.5 MPa the push force is 10053 N and pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, push force reaches 18095 N. The theoretical maximum at 1.0 MPa is 2050 kgf.
No. The SC160X70 is a double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centred. The adjustable air cushion only decelerates the piston — it does not lock or hold position. For load holding without live pressure, add a pilot-operated check valve or an external rod brake.
