About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X100S
The AirTAC SC125X100S is a double-acting, tie-rod pneumatic cylinder delivering 6136 N of push force at 0.5 MPa (11045 N at the 0.9 MPa max operating pressure). With a 100 mm stroke and a 32 mm diameter piston rod, this ISO 6430 class cylinder is built for heavy linear actuation where robust force and moderate travel are required.
A built-in magnet (-S suffix) is fitted as standard on this model, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for contactless end-of-stroke or mid-position sensing. The body length A is 203 mm, giving a total extended length of approximately 303 mm. Ports are PT1/2 with an M27x2 rod thread, and the adjustable air cushion (28 mm length) decelerates the piston smoothly at each end of travel.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X100S Is Used
Heavy Press & Clamping
The 6136 N push force at 0.5 MPa makes the SC125 ideal for pneumatic clamping fixtures, small forming presses, and riveting stations where consistent, high clamping pressure is essential.
Material Handling & Stops
Use this cylinder for heavy-duty conveyor stops, pallet lifters, and part ejectors. The built-in magnet enables precise sensor feedback to confirm part presence or cylinder position in automated lines.
Industrial Gate & Damper Actuation
With its robust 32 mm rod and ISO 6430 class construction, the SC125X100S reliably actuates heavy hopper gates, diverter chutes, and large ventilation dampers in demanding environments.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X100S the Right Cylinder?
Select the SC125 bore when your application needs between roughly 6000 N and 11000 N of pneumatic force at standard plant pressures. If your load is lighter (around 3900 N at 0.5 MPa), stepping down to the SC100 bore reduces air consumption and physical size. For strokes of 300 mm or more on this 32 mm rod, evaluate side-load forces carefully—an external guide rail or a guided cylinder is recommended to protect the rod bearing from bending moments.
To replace an existing SC125X100S, match five points: 125 mm bore, 100 mm stroke, PT1/2 port thread, the built-in magnet for sensor mounting, and the basic (no bracket) mounting configuration. The SC is a tie-rod cylinder and is shorter than an ISO 15552 profile cylinder, so it is not a drop-in replacement for that standard.
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 SC125X100S FAQ
At 0.5 MPa (5 bar), the push force is 6136 N and the pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, push force reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf. Always size the cylinder using the force at your actual working pressure.
Yes. The -S suffix in SC125X100S indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel's external tie-rod slots to detect piston position without additional brackets.
