About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X200STC
The SC125X200STC is a large-bore double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa (11045 N at 0.9 MPa). The 125 mm bore and 200 mm stroke combination suits heavy linear push/pull tasks where a compact tie-rod body is preferred over a profile cylinder.
This ISO 6430 class cylinder features a 32 mm piston rod with M27x2 knuckle thread, a 28 mm adjustable air cushion, and a 203 mm body length A. The -S suffix adds a built-in magnet for CMSG/DMSG/EMSG sensors, while the TC suffix supplies a centre trunnion mount (F-SC125TC with TCM1 bracket) for pivoting applications.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X200STC Is Used
Heavy Part Transfer
Pushes or lifts large components on assembly lines. The 200 mm stroke moves pallets or engine blocks between stations with 6136 N of force at standard line pressure.
Clamping & Pressing
Delivers up to 11045 N at 0.9 MPa for pneumatic clamping fixtures, holding large weldments or composite layups securely during processing.
Agricultural Machinery Actuation
Operates chutes, gates, or diverters on harvesters and spreaders. The centre trunnion mount allows the cylinder to pivot, following the arc of a heavy gate.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X200STC the Right Cylinder?
Select the SC125 when the SC100's 3927 N at 0.5 MPa is insufficient for the load. For lower force requirements, stepping down to the 100 mm bore saves energy and space. The 200 mm stroke is well within the 1500 mm maximum standard stroke for this bore.
When replacing an existing cylinder, match five points: 125 mm bore, 200 mm stroke, PT port thread, centre trunnion (TC) mounting, and the built-in magnet (-S). This tie-rod cylinder is shorter than an ISO 15552 design and is not dimensionally interchangeable with that standard.
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 SC125X200STC FAQ
At 0.5 MPa, push force is 6136 N and pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, push force reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
No. The SC series is a tie-rod cylinder conforming to ISO 6430 class for large bores. Its body length A (203 mm for the 125 bore) is shorter than a typical ISO 15552 cylinder, so mounting dimensions and overall length will differ. It directly replaces another AirTAC SC125 with matching stroke, port, and mount.
