About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X225TC
The SC125X225TC is a double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at 0.9 MPa, making it suitable for heavy pressing and clamping tasks. Its 32 mm diameter piston rod and 28 mm adjustable air cushion provide robust guidance and smooth end-of-stroke deceleration for the 225 mm stroke.
This model is configured with a TC centre trunnion mount, supplied with the TCM1 bracket (F-SC125TC), allowing the cylinder to pivot during operation. As part of the ISO 6430 class tie-rod series, it features a PT1/2 port and operates reliably within a standard temperature range of -20 to +70 °C using TPU seals.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X225TC Is Used
Heavy Part Transfer
The 225 mm stroke and pivoting trunnion mount allow this cylinder to push heavy pallets or components between conveyor lines, accommodating the arcing motion of a lift-and-transfer mechanism.
Industrial Clamping
With over 11000 N of force at 0.9 MPa, it provides the high clamping pressure needed to secure large workpieces during machining, welding, or assembly processes.
Press-Fit Operations
The robust 32 mm rod resists buckling under the high thrust required for press-fit assembly of bearings, bushings, or pins into heavy castings and housings.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X225TC the Right Cylinder?
For applications requiring slightly less force, consider stepping down to the 100 mm bore which provides 3927 N at 0.5 MPa. If higher force is needed, the 160 mm bore offers 10053 N at the same pressure. The 225 mm stroke is within the standard range for this bore, but ensure any side loads are managed with external guides, as the rod bearing is not designed to support significant bending moments.
When replacing an existing cylinder, match five key points: 125 mm bore, 225 mm stroke, PT1/2 port thread, TC centre trunnion mounting with TCM1 bracket, and the absence of a built-in magnet. This ensures a direct dimensional and functional swap with another AirTAC SC125 series unit.

- ✓ 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 SC125X225TC FAQ
At the standard operating pressure of 0.5 MPa, the push force is 6136 N and the pull force is 5734 N. 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 TC suffix indicates it is equipped with a centre trunnion mount. This allows the cylinder body to pivot, making it ideal for applications where the load moves through an arc. It is supplied with the TCM1 trunnion bracket (order code F-SC125TC).
