About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X460S
The SC125X460S is a double-acting tie-rod cylinder delivering 6136 N 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 make it a robust choice for heavy linear actuation within a 460 mm stroke.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for non-contact position sensing. The ISO 6430 class big-bore design operates on 40 µm filtered air from 0.15–1.0 MPa, with PT1/2 ports and a temperature range of -20 to +70 °C using standard TPU seals.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X460S Is Used
Heavy Part Clamping
The 11045 N thrust at 0.9 MPa securely clamps large weldments or castings in machining centres, with sensor confirmation of the clamped position via the built-in magnet.
Pallet Stop & Lift
Deploys a robust pallet stop or lift station on a heavy conveyor line. The 6136 N force at standard shop air easily handles loaded pallets, while the 28 mm cushion absorbs impact quietly.
Press & Forming Assist
Provides the high, consistent push force needed for a 460 mm stroke in a small forming or assembly press. The magnet enables end-of-stroke sensing to trigger the return sequence.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X460S the Right Cylinder?
Choose the SC125 bore when your application needs push force in the 6136 N (at 0.5 MPa) to 11045 N (at 0.9 MPa) range. If your load is lighter, stepping down to an SC100 bore saves space and air consumption (3927 N at 0.5 MPa). For higher force, the SC160 provides 10053 N at 0.5 MPa.
At 460 mm stroke, the 32 mm rod is well-supported, but any significant side load still requires an external guide or a guided cylinder to prevent rod bearing wear and bending. For a direct replacement, match bore (125 mm), stroke (460 mm), PT1/2 port thread, the built-in magnet (-S), and the basic (no bracket) mounting configuration.
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 SC125X460S FAQ
At 0.7 MPa supply pressure, the SC125 bore generates 8590 N of push force. The maximum operating push force at 0.9 MPa is 11045 N. These values are for a standard double-acting cylinder in extension.
Yes, this is a direct replacement for an AirTAC SC125 tie-rod cylinder with a 460 mm stroke, PT1/2 ports, and a built-in magnet for sensors. Ensure your existing mounting (if any) matches the basic body style, or order the required F-SC125 mounting accessory separately.
