About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X500TC
The SC125X500TC is a heavy-duty double-acting tie-rod cylinder delivering 6136 N of push force at 0.5 MPa, rising to 11045 N at the maximum operating pressure of 0.9 MPa. With a 500 mm stroke and a 32 mm diameter piston rod, this model is built for demanding linear applications requiring substantial force over a moderate travel distance. The adjustable air cushion at each end (28 mm length) effectively decelerates the piston, protecting the end caps from impact.
This configuration includes a centre trunnion (TC) mount, supplied complete with the TCM1 bracket (part code F-SC125TC), allowing the cylinder to pivot during operation—ideal for swinging or articulating loads. The standard PT1/2 ports and M27x2 rod thread ensure robust connection, while the TPU seals provide reliable performance within a -20 to +70 °C temperature range.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X500TC Is Used
Pallet Transfer Systems
The 500 mm stroke and pivoting TC mount make this cylinder ideal for lifting and transferring heavy pallets between conveyor lines, where the load path may arc.
Heavy-Duty Clamping
Generates up to 11045 N of force for securely clamping large weldments or castings during machining, with the trunnion mount allowing the fixture to swing clear for part loading.
Material Handling Tippers
Used to pivot heavy bins or hoppers for dumping. The centre trunnion supports the cylinder's weight and allows it to follow the rotating assembly's arc smoothly.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X500TC the Right Cylinder?
For applications needing more force, stepping up to the SC160 bore provides 10053 N at 0.5 MPa. If a shorter, more compact solution is acceptable, the SC100 bore offers 3927 N at the same pressure. For this 500 mm stroke, ensure the rod is adequately supported against side loads; an external guide or a guided cylinder is recommended to prevent rod bending and premature bearing wear.
To guarantee a correct replacement, match five key specifications: 125 mm bore, 500 mm stroke, PT port thread, centre trunnion (TC) mounting, and the absence of a built-in magnet. This SC model is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC125X500TC 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 increases to 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than a comparable ISO 15552 cylinder. It is only a direct dimensional match for another AirTAC SC tie-rod cylinder with the same bore, stroke, mounting, and port thread.
