About the Airtac SC125-160 Standard Cylinder SC125X580S
The SC125X580S is a double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa (11045 N at the 0.9 MPa maximum operating pressure). Its 32 mm diameter piston rod and 28 mm adjustable air cushion handle mid-stroke deceleration smoothly, making the 580 mm stroke well-suited for pressing, clamping, and heavy transfer tasks.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to mount directly on the tie-rod barrel for reliable end-of-stroke detection. The body length A is 203 mm, giving a total extended length of approximately 783 mm.

Where the Airtac SC125-160 Standard Cylinder SC125X580S Is Used
Heavy Pallet Stop
The 6136 N push force at 0.5 MPa and 580 mm stroke reliably raises and lowers heavy pallet stops in conveyor systems, with the built-in magnet confirming position.
Press-Fit Assembly
Delivers up to 11045 N at 0.9 MPa for pressing bearings or bushings. The adjustable cushion protects tooling at the end of the 580 mm stroke.
Material Lift Gate
The 32 mm rod and tie-rod construction handle the bending moments of a 580 mm lift gate stroke. Sensor-ready barrel simplifies interlock logic.
Is the Airtac SC125-160 Standard Cylinder SC125X580S the Right Cylinder?
Choose the SC125 bore when your application needs between roughly 5700 N and 11000 N of push force. If 6136 N at 0.5 MPa is more than required, stepping down to the SC100 bore (3927 N at 0.5 MPa) can reduce air consumption and physical size. For strokes of 300 mm or more, side loads on the 32 mm rod become a design factor — use an external linear guide or a guided cylinder to prevent rod bearing wear and bending.
To replace an existing cylinder, match five points: 125 mm bore, 580 mm stroke, PT port thread, the built-in magnet (-S), and the basic (no bracket) mounting. This SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC125-160 Standard Cylinder SC125X580S FAQ
At 0.5 MPa, the push force is 6136 N; at 0.7 MPa it is 8590 N. The maximum operating push force at 0.9 MPa is 11045 N. These values are for a double-acting cylinder extending; pull force on retract is slightly lower (5734 N at 0.5 MPa) due to the 32 mm rod area.
Yes. The -S suffix means a magnet is built into the piston. You can clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel to detect end-of-stroke position without external brackets.
