About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X1208S
The AirTAC SC160X1208S is a double-acting single-rod pneumatic cylinder delivering a push force of 10053 N at 0.5 MPa and up to 18095 N at the maximum operating pressure of 0.9 MPa. With a 160 mm bore and a 40 mm diameter piston rod, this model is built for heavy linear actuation tasks requiring substantial force over a long working distance.
This specific configuration includes a 1208 mm stroke, which falls within the standard stroke range for the SC160 series (max 1500 mm). The built-in magnet (-S suffix) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the barrel for reliable end-of-stroke or mid-position detection. The tie-rod construction keeps the overall length compact at approximately 1447 mm (body length A of 239 mm plus stroke), and the adjustable air cushion on both ends decelerates the piston smoothly to reduce end-cap impact.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X1208S Is Used
Heavy Material Handling
Provides the high push force needed to lift, tilt, or transfer heavy pallets and steel components in industrial logistics and warehousing systems.
Large Press & Clamping Fixtures
Delivers up to 18095 N of clamping force at 0.9 MPa, ideal for hydraulic-replacement jigs, assembly presses, and heavy-duty welding fixtures requiring consistent pressure.
Agricultural & Forestry Equipment
Operates reliably in dusty outdoor conditions to actuate chutes, gates, and levelling blades on harvesters and processing machinery, with sensor feedback for position confirmation.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X1208S the Right Cylinder?
Select the SC160 when your application requires push forces in the 10000 N class at standard plant air pressure. For a step down in force, the SC125 bore generates 6136 N at 0.5 MPa; for maximum force in the SC family, the SC200 bore delivers 15708 N at the same pressure. Always verify that the 40 mm rod is adequately supported against side loads, especially with strokes exceeding 300 mm—this 1208 mm stroke demands an external guide rail or a guided cylinder assembly to prevent rod bending and premature bearing wear.
To replace an existing SC160X1208S, match five points exactly: 160 mm bore, 1208 mm stroke, PT port thread, the built-in magnet (-S), and the basic (no bracket) mounting style. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders; it must be replaced with another AirTAC SC or an equivalent tie-rod design.
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 SC160X1208S 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. The theoretical maximum force at 1.0 MPa is 2050 kgf.
No. The SC160X1208S is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is lost or the directional valve is centered, the piston will drift or drop. For load holding, you must add an external rod lock, a pilot-operated check valve, or a mechanical brake.
