About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X50S
The SC160X50S is a double-acting pneumatic cylinder delivering a substantial push force of 10053 N at 0.5 MPa, making it ideal for heavy clamping and pressing tasks over a short 50 mm stroke. Its 40 mm diameter piston rod and 29 mm adjustable air cushion provide robust deceleration for high-inertia loads.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors on the tie-rod barrel for precise end-of-stroke position feedback without external brackets.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X50S Is Used
Heavy-Duty Clamping
Delivers over 10,000 N of force at standard line pressure, securely holding large weldments or castings during machining.
Die Cushion Actuation
Short 50 mm stroke with adjustable cushioning controls the impact in small die-cushion or knockout applications in metal forming.
Pallet Stop Positioning
Integrated magnet sensors confirm retracted/extended status, making it a reliable choice for heavy pallet stops in automated logistics.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X50S the Right Cylinder?
For applications needing slightly less force, the 125 mm bore SC series provides 6136 N push at 0.5 MPa. If 10053 N is insufficient, stepping up to the 200 mm bore yields 15708 N. The SC160 is a tie-rod cylinder with a PT3/4 port; when replacing, match bore, stroke, port thread, and ensure the magnet option (-S) is present if sensors are used. For strokes over 300 mm, consider external guides to protect the 40 mm rod from side loads.
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 SC160X50S FAQ
At 0.5 MPa, 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 reaches 18095 N.
Yes. The -S suffix indicates a built-in magnet, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors can be clamped directly onto the cylinder's tie-rod barrel for contactless position sensing.
