About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X330TC
The AirTAC SC125X330TC 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, clamping, and forming tasks. Its 32 mm diameter piston rod and 28 mm adjustable air cushion provide robust guidance and smooth deceleration across the 330 mm stroke.
This model includes the TC centre trunnion mount (F-SC125TC bracket supplied), allowing the cylinder to pivot during operation for swinging or articulating loads. As a genuine AirTAC tie-rod cylinder, it is built for reliable service in demanding industrial environments.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X330TC Is Used
Heavy Part Transfer
Pivoting transfer station for large castings or weldments, using the trunnion mount to swing between conveyor lines with 6 kN of push force.
Industrial Compaction
Waste or recycling baler ram applying up to 11045 N at full pressure, with the trunnion absorbing reaction forces as the platen angle changes.
Clamping & Fixturing
Heavy-duty welding fixture clamp that pivots clear for part loading, using the SC125X330TC's 32 mm rod and trunnion mount for stable, repeatable clamping.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X330TC the Right Cylinder?
For applications needing more force, stepping up to the 160 mm bore provides 10053 N at 0.5 MPa. If a smaller footprint is required, the 100 mm bore offers 3927 N. The 330 mm stroke is within the 1500 mm maximum standard range for this bore, ensuring standard lead times.
At this stroke length, side loads must be managed carefully. An external guide or guided cylinder is recommended to protect the rod bearing from bending moments. For direct replacement, match the 125 mm bore, 330 mm stroke, PT port thread, TC centre trunnion mount, and ensure the replacement cylinder has the same tie-rod construction.
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 SC125X330TC FAQ
At 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 reaches 11045 N.
Yes, the TC suffix indicates a centre trunnion mount, which is specifically designed for applications where the cylinder body needs to pivot. The mounting bracket (F-SC125TC) is included.
