About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1900STC
The AirTAC SC125X1900STC is a heavy-duty double-acting tie-rod cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa. This model features a substantial 32 mm piston rod and an extended 1900 mm stroke, making it suitable for large-scale material handling and positioning tasks where a long, powerful linear movement is required.
This specific configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (TC) supplied with the TCM1 bracket for pivoting applications. With a 28 mm adjustable air cushion and PT1/2 ports, it provides reliable end-of-stroke deceleration. As a non-standard stroke exceeding the 1500 mm maximum, this is a made-to-order genuine AirTAC cylinder.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1900STC Is Used
Pallet and Container Handling
Provides the long 1900 mm reach and high force needed to push heavy pallets or containers across wide roller conveyors and transfer stations in distribution centres.
Agricultural Equipment Actuation
Controls large chutes, gates, or hopper doors on harvesters and processing equipment, where a powerful, long-stroke cylinder with a pivoting trunnion mount is essential for remote operation.
Large-Format Press Feed Systems
Delivers the extended linear motion required to feed large sheet materials into stamping presses or CNC routers, with magnetic sensors confirming full extension and retraction for automated cycle control.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1900STC the Right Cylinder?
Select the SC125 for applications demanding over 6000 N of force at standard plant pressure. If your load requires less force, stepping down to the SC100 bore reduces push force to 3927 N at 0.5 MPa, offering a more compact and cost-effective solution. For strokes of this length, external side loads on the 32 mm rod are a critical design factor; an external guide or linear rail system is mandatory to prevent rod bending and premature bearing wear.
For a direct replacement, match five key specifications: the 125 mm bore, the exact 1900 mm non-standard stroke, the PT1/2 port thread, the centre trunnion (TC) mounting with the F-SC125TC accessory, and the built-in magnet (-S) for sensor compatibility. Always verify the total extended body length against your machine envelope.
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 SC125X1900STC FAQ
At the maximum operating pressure of 1.0 MPa, the theoretical push force is 1251 kgf (12270 N). At the standard 0.5 MPa, the push force is 6136 N and the pull force is 5734 N.
For a 1900 mm stroke, the 32 mm rod is highly susceptible to bending under side loads. You must use an external guide system, such as a hardened guide rod assembly or a linear rail, to absorb all transverse forces. The cylinder's rod bearing is designed only to support the axial thrust load, not side loading.
