About the Airtac SC80 Standard Cylinder SC80X550TC
The AirTAC SC80X550TC is an 80 mm bore double-acting pneumatic cylinder delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa. With a 550 mm stroke and a 25 mm diameter piston rod, this model is well-suited for medium-duty linear applications requiring a substantial working envelope.
This configuration includes a centre trunnion mount (TC), supplied with the TCM1 bracket (F-SC80TC), allowing the cylinder body to pivot during operation to accommodate swinging or arcing loads. The standard TPU seals provide a reliable operating temperature range of -20 to +70 °C, and the PT1/4 port threads ensure straightforward pneumatic connections.

Where the Airtac SC80 Standard Cylinder SC80X550TC Is Used
Conveyor Diverters
The 4523 N push force at 0.9 MPa and centre trunnion mount make this cylinder ideal for pivoting diverter gates on material handling lines, smoothly redirecting packages or products.
Clamping Fixtures
Delivers consistent, controlled clamping force for medium-to-large workpieces in CNC machining or welding jigs, where the trunnion mount allows the cylinder to swing clear for part loading.
Agricultural Equipment
Suitable for actuating pivoting chutes or hopper doors on farming machinery, providing robust force and reliable operation in dusty environments with standard TPU seals.
Is the Airtac SC80 Standard Cylinder SC80X550TC the Right Cylinder?
For applications needing more force, stepping up to the SC100 bore increases push force to 3927 N at 0.5 MPa. If a shorter, more compact footprint is required, the SC63 bore provides 1559 N. At a 550 mm stroke, the extended rod length requires careful alignment; any side loading can cause rod bending or premature bearing wear. For such applications, consider pairing this cylinder with an external linear guide or evaluating a guided cylinder assembly.
To ensure a direct replacement, match five key specifications: the 80 mm bore, the 550 mm stroke, the PT port thread, the TC centre trunnion mounting configuration, and the absence of a built-in magnet. This model is a tie-rod design 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 SC80 Standard Cylinder SC80X550TC FAQ
At the standard operating pressure of 0.5 MPa, it generates 2513 N pushing and 2268 N pulling. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It is only a direct dimensional replacement for another AirTAC SC80 tie-rod cylinder with matching stroke, PT ports, and TC centre trunnion mount.
