About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X170S
The SC125X170S is a double-acting pneumatic cylinder delivering 6136 N push and 5734 N pull at 0.5 MPa, scaling to 11045 N at the 0.9 MPa maximum operating pressure. Its 170 mm stroke suits medium-travel clamping, pressing, and lifting stations where magnetic piston sensing is required.
This model includes a factory-installed magnet (-S suffix), enabling direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the tie-rod barrel. The 32 mm diameter piston rod and M27x2 knuckle thread provide robust guidance, while the 28 mm adjustable air cushion at each end decelerates the load smoothly. Ports are PT1/2.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X170S Is Used
Heavy Clamping Fixtures
The 6136 N push force at 0.5 MPa securely clamps large weldments and machined castings, with magnetic sensors confirming jaw position before the cycle starts.
Pallet Stop & Lift
Acts as a robust pallet stop or lift-and-locate unit on heavy conveyor lines; the built-in magnet lets sensors detect end-of-stroke without external brackets.
Press & Forming Assist
Delivers up to 11045 N at 0.9 MPa for light press-fit, forming, or riveting operations, with adjustable cushioning to protect tooling at the end of the 170 mm stroke.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X170S the Right Cylinder?
For higher force at the same pressure, step up to the SC160 bore (10053 N push at 0.5 MPa); for a lighter, more compact build, the SC100 bore offers 3927 N. This 170 mm stroke is well within the 1500 mm maximum standard stroke for bore 125. When replacing an existing cylinder, match five points: 125 mm bore, 170 mm stroke, PT1/2 ports, the built-in magnet for sensors, and the basic (no bracket) mounting style.
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 SC125X170S FAQ
At 0.5 MPa the cylinder pushes with 6136 N and pulls with 5734 N. At 0.7 MPa push force rises to 8590 N, and at the maximum operating pressure of 0.9 MPa it reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
Yes. The -S suffix means a magnet is built into the piston, so AirTAC CMSG (reed), DMSG, or EMSG (solid-state) sensors clamp directly onto the cylinder's tie-rod barrel. No external actuator flags or brackets are needed.
