About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X680S
The AirTAC SC160X680S is a double-acting single-rod pneumatic cylinder with a 160 mm bore and 680 mm stroke, featuring a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors. This model delivers a substantial push force of 10053 N at 0.5 MPa and up to 18095 N at the maximum operating pressure of 0.9 MPa, making it suitable for heavy pushing, pressing, and clamping tasks.
Built as a robust tie-rod cylinder, the SC160X680S uses a 40 mm diameter piston rod with an M36x2 knuckle thread and PT3/4 port connections. The adjustable air cushion at both ends (29 mm cushion length) decelerates the piston smoothly, reducing end-of-stroke impact. With a body length A of 239 mm, the total extended length is approximately 919 mm, providing a compact yet powerful solution for industrial automation.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X680S Is Used
Pallet Transfer Systems
The 10053 N push force at 0.5 MPa easily transfers heavy pallets or large workpieces between conveyor lines, with the 680 mm stroke covering wide transfer gaps.
Waste Compaction
Ideal for driving a compaction plate in recycling or waste management equipment, delivering up to 18095 N of force at 0.9 MPa to crush and densify materials.
Heavy-Duty Clamping
Used in large welding fixtures or machining centres to clamp oversized components securely. The built-in magnet allows sensors to confirm clamp engagement before the cycle starts.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X680S the Right Cylinder?
Select the SC160 when your application requires a force class between the SC125 (6136 N push at 0.5 MPa) and the SC200 (15708 N push at 0.5 MPa). For this 680 mm stroke, ensure the 40 mm rod is adequately supported against side loads; if the load is not guided externally, consider adding an external guide rail or switching to a guided cylinder to prevent rod bending and premature bearing wear.
To replace an existing cylinder, match five key points: 160 mm bore, 680 mm stroke, PT3/4 port thread, the built-in magnet (-S suffix for sensor compatibility), and the basic mounting style (no integral bracket). This ensures a direct dimensional and functional swap with another AirTAC SC160 tie-rod cylinder.
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 SC160X680S 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.
Yes. The -S suffix in SC160X680S indicates a built-in magnet. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel to detect piston position without additional brackets.
