About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X185
The AirTAC SC160X185 is a robust double-acting tie-rod cylinder delivering 10053 N of push force at 0.5 MPa, scaling up to a substantial 18095 N at the maximum operating pressure of 0.9 MPa. With a 185 mm stroke, this model is well-suited for medium-travel clamping, pressing, and heavy-duty material handling tasks where a compact retracted length is beneficial.
This cylinder features a 40 mm diameter piston rod with an M36x2 male thread and a PT3/4 port for high flow. The adjustable air cushion, with a 29 mm cushion length, effectively decelerates the piston at the end of stroke to reduce impact and noise, protecting the end caps during high-cycle operation.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X185 Is Used
Heavy-Duty Clamping
The 18095 N force at 0.9 MPa provides immense clamping power for welding fixtures and assembly jigs, securely holding large workpieces during fabrication.
Pallet Stop & Transfer
With a 185 mm stroke and 10053 N of push at standard pressure, this cylinder is ideal for stopping and transferring heavy pallets on gravity or powered roller conveyors.
Waste Compaction
Delivers the high force required for compacting cardboard, plastics, or other recyclable materials in small to medium-sized baling or compaction machinery.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X185 the Right Cylinder?
For applications requiring slightly less force, the SC125 bore provides 6136 N of push force at 0.5 MPa, while stepping up to the SC200 bore offers 15708 N. When replacing an existing cylinder, ensure a precise match across five key points: 160 mm bore, 185 mm stroke, PT3/4 port thread, basic mounting (no accessories), and the absence of a magnet. The SC is a tie-rod cylinder and is dimensionally shorter than an ISO 15552 profile cylinder, so it is not a direct drop-in replacement for that standard.
For this 185 mm stroke, the 40 mm rod is inherently rigid for most axial loads. However, if the application involves any side loading, an external guide rail or a guided cylinder is strongly recommended to protect the rod bearing and seals from premature wear and bending.
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 SC160X185 FAQ
At the standard 0.5 MPa operating pressure, 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 increases to 18095 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
No, as a standard double-acting cylinder, it will not hold a load if air pressure is exhausted or the directional valve is centered. The piston can drift or drop. For load-holding applications, you must add a pilot-operated check valve or an external mechanical rod brake.
