About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X1700S
The SC160X1700S is a large-bore double-acting pneumatic cylinder delivering substantial force for heavy industrial applications. At 0.5 MPa it generates 10053 N pushing and 9425 N pulling, rising to a powerful 18095 N push at the maximum operating pressure of 0.9 MPa.
This model features a 1700 mm stroke, which exceeds the standard maximum of 1500 mm for the 160 mm bore, making it a made-to-order non-standard configuration. It includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, a 40 mm diameter piston rod with M36x2 threads, and 28 mm adjustable air cushioning for controlled end-of-stroke deceleration.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X1700S Is Used
Sawmill Log Handling
Provides the high force and long stroke needed to position and clamp large-diameter logs on carriages and infeeds, with sensor feedback for automated cut-to-length systems.
Heavy-Duty Agricultural Press
Delivers the sustained push force for compacting silage or operating large baling press rams, where the 1700 mm stroke accommodates deep compression chambers.
Structural Steel Bending Jig
Powers a long-stroke ram in a custom bending fixture for heavy structural steel sections, using the built-in magnet for end-of-stroke sensing to control bend angle.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X1700S the Right Cylinder?
Select the SC160 for applications requiring forces in the 10 kN class. If your load requires slightly less force, consider stepping down to the SC125 bore, which provides 6136 N at 0.5 MPa. For a 1700 mm stroke, managing side loads is critical; an external guide or a guided cylinder is strongly recommended to prevent bending stress on the 40 mm rod and premature bearing wear.
For direct replacement, ensure the new cylinder matches these five points: 160 mm bore, 1700 mm stroke, PT3/4 port thread, the built-in magnet for sensor compatibility, and the basic mounting configuration. This is a genuine AirTAC SC tie-rod cylinder, which is shorter than an ISO 15552 profile and 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 SC160X1700S FAQ
At the standard 0.5 MPa operating pressure, the push force is 10053 N and the pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 18095 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
A stroke of 1700 mm on a 40 mm diameter rod creates a high risk of rod buckling and bearing damage under side loads. You must use an external linear guide system or a self-guided cylinder to absorb transverse forces. The adjustable air cushion only decelerates the piston at the stroke end and does not support or guide the load.
