About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X430S
The SC125X430S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 125 mm bore with a 430 mm stroke. It generates a substantial push force of 6136 N at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa, making it suitable for heavy linear actuation tasks. The built-in magnet (-S suffix) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for precise end-of-stroke or mid-stroke position feedback.
This model features a robust 32 mm diameter piston rod with an M27x2 knuckle thread and PT1/2 port connections. With a body length A of 203 mm and an adjustable air cushion stroke of 28 mm, it provides smooth deceleration at stroke ends. As an ISO 6430 class cylinder, it operates within a speed range of 30-500 mm/s and a standard temperature range of -20 to +70 °C using its TPU/NBR seals.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X430S Is Used
Heavy Pallet Lifting
Provides the high force needed for lifting and positioning heavy pallets or containers in automated storage and retrieval systems, with sensor feedback for precise lift height control.
Logistics Sortation Gates
Actuates heavy-duty diverter gates on high-speed conveyor lines. The built-in magnet allows sensors to confirm gate position, ensuring reliable package routing.
Industrial Press Feed
Delivers powerful, controlled linear motion for feeding heavy stock into stamping presses or forming machines, with adjustable cushioning to manage high inertial loads.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X430S the Right Cylinder?
Selecting the SC125X430S means choosing a high-force actuator for demanding applications. If your load requires less force, consider stepping down to the 100 mm bore model, which provides 3927 N of push force at 0.5 MPa. For even higher force requirements, the 160 mm bore version delivers 10053 N at the same pressure. This cylinder's 430 mm stroke is well within the 1500 mm maximum standard stroke for the 125 mm bore.
For strokes of this length, always evaluate side-loading conditions. An unsupported 430 mm stroke with a 32 mm rod can be susceptible to bending under significant lateral forces. To ensure long service life, use an external guide system or a guided cylinder configuration to isolate the rod and bearings from side loads. When replacing this unit, match five key attributes: 125 mm bore, 430 mm stroke, PT1/2 port thread, the built-in magnet (-S), and the basic (no bracket) mounting style.
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 SC125X430S FAQ
At 0.5 MPa, the cylinder delivers 6136 N of push force and 5734 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
Yes. The -S suffix in the model code SC125X430S indicates a built-in magnet is integrated into the piston. This allows you to clamp compatible AirTAC CMSG, DMSG, or EMSG sensors directly onto the cylinder barrel to detect piston position without additional brackets.
