About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1160STC
The SC125X1160STC is a double-acting pneumatic cylinder delivering a substantial 6136 N push force at 0.5 MPa (11045 N at the 0.9 MPa maximum operating pressure), making it suitable for heavy linear actuation tasks. With a 125 mm bore and a long 1160 mm stroke, this model features a 32 mm piston rod, PT1/2 ports, and an adjustable air cushion length of 28 mm to decelerate the high-inertia load smoothly at end-of-travel.
This configuration includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, enabling precise end-of-stroke or mid-stroke position feedback. The TC centre trunnion mount (supplied with the TCM1 bracket, part code F-SC125TC) allows the cylinder body to pivot, accommodating swinging or articulating loads. Operating on 40 µm filtered air from 0.15–1.0 MPa, it uses standard TPU seals for a -20 to +70 °C range and PT threads.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1160STC Is Used
Heavy Part Transfer
Moves large castings or weldments between stations on a pivoting transfer arm, using the trunnion mount for smooth arcing motion and sensors to confirm extend/retract.
Press-Fit Assembly
Generates up to 11045 N of push force at 0.9 MPa for pressing bearings or bushings into housings, with adjustable cushioning to prevent impact damage at the end of the stroke.
Pallet Lift & Tilt
Pivots a heavy pallet dispenser or tilt table via the centre trunnion, using the 1160 mm stroke to achieve a large angular range while sensors monitor the home and tilted positions.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1160STC the Right Cylinder?
For applications requiring slightly less force, stepping down to the SC100 bore provides 3927 N push at 0.5 MPa, while stepping up to the SC160 bore offers 10053 N. Given the 1160 mm stroke, side-load management is critical: the long, unsupported 32 mm rod is susceptible to bending under radial forces. Always use an external guide system or a self-guided actuator if side loads are present, and ensure the load is aligned axially with the rod.
To replace an existing cylinder, match five key points: 125 mm bore, 1160 mm stroke, PT port thread, centre trunnion (TC) mounting with the TCM1 bracket, and the integrated magnet for sensor compatibility. This SC series is a tie-rod cylinder, not an ISO 15552 profile, but as a large bore it aligns with the ISO 6430 class for robust, heavy-duty applications.
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 SC125X1160STC FAQ
At 0.5 MPa, the cylinder provides 6136 N pushing and 5734 N pulling. 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.
No. With a 1160 mm stroke and a 32 mm rod, the cylinder is highly vulnerable to rod bending and bearing wear from side loads. An external guide rail, rod support, or a guided cylinder must be used to absorb any radial forces and ensure reliable operation.
