About the Airtac SC125-160 Standard Cylinder SC160X125S
The SC160X125S is a large-bore double-acting tie-rod cylinder delivering 10053 N push force at 0.5 MPa and up to 18095 N at the 0.9 MPa maximum operating pressure. Its 125 mm stroke suits medium-travel clamping and pressing operations where magnetic piston sensing is required.
A 40 mm diameter chrome-plated rod and PT3/4 ports provide robust fluid power. The built-in magnet (suffix -S) allows CMSG/DMSG/EMSG reed or solid-state sensors to clamp directly onto the barrel for end-of-stroke or mid-position confirmation without external brackets. The adjustable air cushion at each end is 29 mm long, decelerating heavy loads smoothly.

Where the Airtac SC125-160 Standard Cylinder SC160X125S Is Used
Heavy-Duty Clamping
The 18095 N thrust at 0.9 MPa locks large weldments or castings in place during machining, with magnetic sensors confirming clamp engagement.
Press-Fit Assembly
Delivers controlled force for installing bearings or bushings. The adjustable cushion protects the rod and tooling from impact at the end of the 125 mm stroke.
Pallet Stop & Lift
Stops and lifts heavy pallets on conveyor lines. The built-in magnet enables position feedback to the PLC for interlocked material handling sequences.
Is the Airtac SC125-160 Standard Cylinder SC160X125S the Right Cylinder?
This 160 mm bore cylinder is a high-force solution, stepping up from the 125 mm bore (6136 N at 0.5 MPa). If your load is below 6000 N, consider the SC125 series to reduce air consumption and physical size. For strokes over 300 mm, evaluate side-load and rod-bearing bending; an external guide or guided cylinder is recommended.
For direct replacement, match five points: 160 mm bore, 125 mm stroke, PT port thread, basic mounting (no factory-fitted bracket), and the -S magnet for sensor compatibility. The SC160 is a tie-rod design, shorter than an ISO 15552 cylinder, so dimensional interchangeability should be verified against another AirTAC SC160 or equivalent tie-rod unit.
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 SC125-160 Standard Cylinder SC160X125S FAQ
At 0.7 MPa (7 bar) supply pressure, the push force is 14074 N. The pull force on the retract stroke is 9425 N at 0.5 MPa, due to the area reduction from the 40 mm rod.
Yes. The -S suffix denotes a built-in magnet in the piston, making this model directly compatible with AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors, which clamp onto the tie-rod barrel without extra mounting hardware.
