About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X175TC
The AirTAC SC125X175TC is a double-acting tie-rod cylinder delivering 6136 N of push force at 0.5 MPa (11045 N at the maximum operating pressure of 0.9 MPa). With a 125 mm bore and 175 mm stroke, this model is built for heavy-duty linear actuation where a pivoting mount is required.
The cylinder features a 32 mm piston rod with an M27x2 knuckle thread and a 28 mm adjustable air cushion to decelerate end-of-stroke impact. The TC suffix indicates a centre trunnion mount, supplied with the TCM1 bracket (F-SC125TC), allowing the cylinder body to pivot during operation.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X175TC Is Used
Heavy Press Tool Actuation
Provides the high clamping and pressing forces needed for metal forming and stamping tools, with the trunnion mount allowing the cylinder to align with the tooling's arc of motion.
Large Part Diverter Gates
Powers diverter gates on heavy-duty conveyor systems for pallets or large packages. The pivoting action from the TC mount perfectly suits the gate's swinging movement.
Industrial Mixer Tilt Mechanism
Controls the tilt angle of large industrial mixing drums or vessels. The high force output handles the heavy, off-centre loads, while the trunnion mount supports the pivoting structure.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X175TC the Right Cylinder?
Choose the SC125 when the 100 mm bore's 3927 N force at 0.5 MPa is insufficient; step up to the SC160 for 10053 N if the load exceeds this model's capacity. The centre trunnion mount is ideal for applications requiring the cylinder to swing through an arc, but ensure the pivot axis is aligned to avoid binding.
For this 175 mm stroke, side-load forces are generally manageable, but always avoid direct radial loads on the rod. For a drop-in replacement, match the 125 mm bore, 175 mm stroke, PT port thread, centre trunnion (TC) mounting, and the absence of a magnet.
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 SC125X175TC FAQ
At the standard operating pressure of 0.7 MPa, the push force is 8590 N and the pull force is 5734 N. The maximum theoretical push force at 1.0 MPa is 1251 kgf.
No. As a standard double-acting cylinder, the SC125X175TC will drift if air pressure is lost or the directional valve is centered. The adjustable air cushion only decelerates the piston at the stroke ends and does not act as a lock. A pilot-operated check valve or external mechanical brake is required for position holding.
