About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X850S
The AirTAC SC160X850S is a double-acting single-rod tie-rod cylinder delivering 10053 N push force at 0.5 MPa (18095 N at 0.9 MPa), ideal for heavy-duty medium-stroke linear actuation. Its 40 mm diameter piston rod and 29 mm adjustable air cushion handle substantial kinetic energy, while the built-in magnet allows CMSG/DMSG/EMSG sensors to clamp directly onto the barrel for rod-position feedback.
With an 850 mm stroke and a body length A of 239 mm, the extended length reaches approximately 1089 mm. This model operates on 40 µm filtered air at 0.15-1.0 MPa and -20 to +70 °C with standard TPU seals. The PT3/4 port and M36x2 rod thread connect robustly into high-flow circuits.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X850S Is Used
Pallet Transfer
The 10053 N push at 0.5 MPa reliably moves heavy pallets across 850 mm transfer stations in logistics and warehousing.
Press-Fit Assembly
Delivers up to 18095 N at 0.9 MPa for pressing bearings, bushings, or pins into heavy castings with controlled, cushioned deceleration.
Material Handling Gate
Actuates a large diverter gate or chute in mining or aggregate processing, using the built-in magnet for end-of-stroke position confirmation.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X850S the Right Cylinder?
For applications needing slightly less force, the 125 mm bore SC125 series provides 6136 N push at 0.5 MPa; for maximum force in this family, step up to the SC200 bore with 15708 N push. At 850 mm stroke, the 40 mm rod is robust, but any significant side load should be managed with an external guide or linear bearing to protect the rod bearing and piston seals from bending moments.
When replacing an existing cylinder, match five points exactly: 160 mm bore, 850 mm stroke, PT3/4 port thread, the built-in magnet (-S suffix), and the basic mounting (no bracket). This SC cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC160X850S FAQ
At 0.7 MPa operating pressure, the push force is 14074 N. The maximum push force at 0.9 MPa is 18095 N. The theoretical force at 1.0 MPa is 2050 kgf.
Yes. The -S suffix indicates a built-in magnet, so AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors can be clamped directly onto the barrel to detect piston position without additional brackets.
