About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X25S
The AirTAC SC160X25S is a double-acting tie-rod cylinder delivering 10053 N push force at 0.5 MPa (18095 N at 0.9 MPa). Its 40 mm piston rod and 29 mm adjustable air cushion handle short, high-force clamping or pressing strokes with controlled deceleration.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to mount directly on the barrel for non-contact position sensing. The 25 mm stroke keeps the overall length compact at approximately 264 mm (body length A 239 mm + stroke), ideal for tight machine envelopes.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X25S Is Used
Heavy Press & Clamp
Short 25 mm stroke with 18095 N max thrust securely clamps large weldments, stampings, or composite layups in industrial fixtures.
Automated Assembly
Built-in magnet enables precise end-of-stroke sensing for high-force insertion, riveting, or staking stations on automated lines.
Material Handling Gate
Positions heavy diverter gates or stops on gravity conveyors, with sensor feedback confirming open/closed status for interlock safety.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X25S the Right Cylinder?
Choose the SC160 for heavy-duty applications where the SC125 (push 6136 N at 0.5 MPa) is undersized. If your load is below 6000 N, stepping down to the 125 mm bore saves space and cost. For replacement, match five points: 160 mm bore, 25 mm stroke, PT port thread, basic mounting (no bracket), and the -S magnet for sensor compatibility. The 40 mm rod is robust, but for strokes above 300 mm, always evaluate side-load bending moments—an external guide or guided cylinder prevents rod bearing wear.
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 SC160X25S FAQ
At 0.5 MPa it produces 10053 N push force; at 0.7 MPa, 14074 N; and at the maximum operating pressure of 0.9 MPa, it reaches 18095 N. The theoretical force at 1.0 MPa is 2050 kgf.
Yes. The -S suffix denotes a built-in magnet on the piston, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clamp directly onto the tie-rod barrel for reliable position feedback.
