About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X800S
The AirTAC SC160X800S is a double-acting single-rod tie-rod cylinder delivering 10053 N push force at 0.5 MPa (18095 N at the 0.9 MPa maximum operating pressure). With an 800 mm stroke and a 40 mm diameter piston rod, it is built for heavy linear actuation tasks where mid-to-long travel and substantial thrust are required.
This model includes the built-in magnet suffix -S, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for non-contact position sensing. The adjustable air cushion (29 mm length) decelerates the piston at stroke ends, and the standard PT3/8 port thread connects to common pneumatic fittings. The body length A is 239 mm, giving a total extended length of approximately 1039 mm.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X800S Is Used
Sawmill Log Handling
Pushes and positions large logs or timber cants on infeed conveyors. The 10053 N force at 0.5 MPa moves heavy wood, while the built-in magnet enables end-of-stroke detection for automated saw lines.
Heavy Press Feeding
Transfers large metal sheets or blanks into stamping presses. The 800 mm stroke covers the full press bed depth, and the 40 mm rod resists buckling under the high thrust needed to slide heavy stock.
Balers and Compactors
Drives the main compaction ram in recycling balers. The adjustable cushion absorbs the impact energy of the 40 mm rod at end-of-stroke, and the magnet sensors confirm ram position for cycle control.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X800S the Right Cylinder?
For applications needing less force, stepping down to a 125 mm bore reduces push force to 6136 N at 0.5 MPa; for higher thrust, the 200 mm bore provides 15708 N. At 800 mm stroke, the SC160X800S rod is well within the 1500 mm maximum standard stroke for this bore. However, with a long unsupported stroke, side loads must be managed carefully—consider an external linear guide or a guided cylinder configuration to prevent rod bending and premature bearing wear.
To ensure a correct replacement, match five key points: 160 mm bore, 800 mm stroke, PT3/8 port thread, the built-in magnet (-S) for sensor compatibility, and the basic mounting style (no integrated bracket). This cylinder is a direct replacement for another AirTAC SC160X800S or a tie-rod cylinder with identical specifications.

- ✓ 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 SC160X800S FAQ
At 0.7 MPa operating pressure, the push force is 14074 N. The maximum push force at the 0.9 MPa operating limit is 18095 N. The theoretical force at 1.0 MPa is 2050 kgf.
Yes. The -S suffix indicates a built-in magnet on the piston, which is specifically designed for use with AirTAC CMSG, DMSG, or EMSG sensors. The sensors clamp onto the barrel's external tie-rod grooves to detect piston position without physical contact.
