About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X290S
The AirTAC SC125X290S is a double-acting tie-rod cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at 0.9 MPa. With a 32 mm diameter piston rod and M27x2 knuckle thread, it handles substantial linear loads in industrial automation.
This model includes a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for precise end-of-stroke detection. The 290 mm stroke sits well within the standard range for the 125 mm bore, and the adjustable air cushion at both ends decelerates the piston smoothly to reduce impact energy.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X290S Is Used
Heavy Conveyor Actuation
Powers diverters, gates, and stops on wide conveyor lines handling pallets or heavy totes, with 11045 N of force at 0.9 MPa to move stubborn loads.
Press and Clamping
Delivers consistent clamping force in pneumatic toggle presses or welding fixtures, where the 32 mm rod resists deflection under high-pressure hold cycles.
Material Forming Assist
Assists in bending or forming operations for sheet metal and plastics, providing the high push force needed at the start of the stroke to initiate deformation.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X290S the Right Cylinder?
Selecting the SC125X290S means matching a 125 mm bore tie-rod cylinder with a 290 mm stroke, PT ports, and a built-in magnet. If your force requirements are lower, stepping down to the SC100 bore reduces push force to 3927 N at 0.5 MPa, while stepping up to the SC160 provides 10053 N. For strokes over 300 mm on a basic mount, consider an external guide or a guided cylinder to protect the 32 mm rod from side-load bending moments, especially in horizontal applications.
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 SC125X290S FAQ
At 0.5 MPa operating pressure, the SC125X290S produces 6136 N of push force on extension and 5734 N of pull force on retraction. At the maximum operating pressure of 0.9 MPa, the push force increases to 11045 N.
Yes, the -S suffix indicates a built-in magnet in the piston. This allows you to clamp AirTAC CMSG, DMSG, or EMSG series sensors directly onto the tie-rod barrel to detect piston position without external brackets.
