About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X230STC
Delivering 6136 N of push force at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa, the AirTAC SC125X230STC is a heavy-duty double-acting cylinder built for demanding linear applications. This model features a 32 mm diameter piston rod with an M27x2 knuckle thread and a 28 mm adjustable air cushion at each end, ensuring smooth deceleration of large inertial loads.
This configuration includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors and a centre trunnion mount (TC suffix, bracket F-SC125TC with TCM1 included), allowing the cylinder to pivot during operation. With a 230 mm stroke and a compact body length of 203 mm, it is an ISO 6430 class tie-rod cylinder, shorter than a comparable ISO 15552 profile.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X230STC Is Used
Heavy Conveyor Diverters
Pivots a high-speed diverter gate on a mining or aggregate conveyor, using the centre trunnion mount to swing the cylinder body as the gate moves through its arc.
Press Clamping Systems
Applies up to 11045 N of clamping force in a hydraulic press safety interlock, with magnetic sensors confirming the guard is closed before the cycle starts.
Material Handling Tilters
Drives a bin or hopper tilter in a foundry, where the trunnion mount absorbs the angular misalignment and the built-in cushion handles the heavy, shifting load.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X230STC the Right Cylinder?
For applications requiring less force, stepping down to an SC100 bore reduces push force to 3927 N at 0.5 MPa, while an SC160 bore steps up to 10053 N. The 230 mm stroke is well within the 1500 mm maximum standard stroke for this bore. When using a centre trunnion mount on longer strokes, ensure the pivot point is positioned to minimize rod bending moments from the load.
To replace this cylinder, match five key specifications: 125 mm bore, 230 mm stroke, PT port thread, the TC centre trunnion mounting accessory, and the built-in magnet for sensor compatibility. This ensures a drop-in fit without modifying the machine frame or sensor setup.
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 SC125X230STC FAQ
At 0.5 MPa air pressure, the cylinder pushes with 6136 N and pulls with 5734 N. At the maximum operating pressure of 0.9 MPa, the extending force increases to 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
Yes. The -S suffix in the model code indicates a built-in magnetic piston, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors can be clamped directly onto the tie-rod barrel to detect piston position without external brackets.
