About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X500S
The AirTAC SC160X500S is a double-acting tie-rod cylinder delivering 10053 N of push force at 0.5 MPa and up to 18095 N at the maximum operating pressure of 0.9 MPa. With a 40 mm diameter piston rod and a 500 mm stroke, it is built for heavy linear actuation tasks where sensor feedback is required.
The -S suffix denotes a built-in magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for precise end-of-stroke or mid-stroke position sensing. The cylinder features a 29 mm adjustable air cushion at each end to decelerate the piston smoothly, and the body length A is 239 mm, giving a total extended length of approximately 739 mm.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X500S Is Used
Heavy Press & Clamping
With 18095 N of force at 0.9 MPa, the SC160X500S powers large pneumatic presses, assembly fixtures, and material clamping stations requiring consistent high force and sensor-confirmed closure.
Palletising & Transfer Lines
The 500 mm stroke and robust 40 mm rod push heavy pallets or transfer heavy components between conveyor lines, with the magnetic piston enabling sensor-based sequencing.
Industrial Gate & Damper Actuation
Operates large hopper gates, diverter chutes, or ventilation dampers in mining and processing plants, where the built-in magnet provides open/closed position feedback to the control system.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X500S the Right Cylinder?
For applications needing slightly less force, the SC125 bore provides 6136 N push at 0.5 MPa, while the SC200 bore steps up to 15708 N at the same pressure. This SC160X500S model includes a magnet, so it is ready for sensor mounting without external brackets. When replacing an existing cylinder, match five points: 160 mm bore, 500 mm stroke, PT port thread, the built-in magnet (-S), and the basic (no bracket) mounting configuration. At 500 mm stroke, ensure the rod is not subjected to significant side loads; if lateral forces are present, use an external guide rail or a guided cylinder to protect the rod bearing and seals from premature 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 SC160X500S FAQ
At 0.7 MPa (7 bar) supply pressure, the SC160 bore generates 14074 N of push force. The pull force on the retract stroke is 9425 N at 0.5 MPa, reduced by the 40 mm rod area.
Yes. The -S suffix means a magnet is built into the piston, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clamp directly onto the tie-rod barrel to detect piston position without external flags or brackets.
