About the Airtac SC80 Standard Cylinder SC80X630TC
The AirTAC SC80X630TC is a double-acting tie-rod cylinder delivering 2513 N push force at 0.5 MPa (4523 N at 0.9 MPa), built around an 80 mm bore and a 25 mm piston rod. Its 630 mm stroke is well within the 1500 mm maximum standard stroke for this bore, and the body length A of 182 mm keeps the overall package compact for a mid-range industrial actuator.
This model ships with the TC centre trunnion mounting bracket (F-SC80TC including TCM1), allowing the cylinder to pivot freely under swinging or articulating loads. The adjustable air cushion (28 mm length) decelerates the piston at end-of-stroke, reducing impact and extending seal life. PT1/8 ports and M20x1.5 rod threads are standard, and the TPU seals suit operating temperatures from -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X630TC Is Used
Conveyor Diverter Gates
The 630 mm stroke and trunnion mount let this cylinder pivot a diverter gate or flipper on a packaging line, handling repetitive actuation with the 2513 N force needed to move product reliably.
Clamping & Fixturing
Ideal for welding or assembly fixtures where the cylinder body must swing to clear the part. The centre trunnion allows angular movement while the adjustable cushion protects tooling from hard stops.
Agricultural Machinery Linkage
Provides the push-pull motion for a planter row-unit lift or a chute control on a harvester. The TPU seals and tie-rod construction handle dusty, outdoor conditions with filtered air.
Is the Airtac SC80 Standard Cylinder SC80X630TC the Right Cylinder?
For applications needing more force, stepping up to the SC100 bore raises push force to 3927 N at 0.5 MPa, while the SC63 bore offers a lighter 1559 N alternative. At 630 mm stroke, the 25 mm rod is robust, but any side load or off-axis mounting should be managed with an external guide rail or rod-alignment coupler to prevent rod-bearing bending and premature seal wear.
When replacing an existing cylinder, match five points: 80 mm bore, 630 mm stroke, PT1/8 port thread, TC centre-trunnion mounting (F-SC80TC), and the absence of a magnet. The SC 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 SC80X630TC FAQ
At 0.5 MPa the cylinder provides 2513 N pushing and 2268 N pulling. At the maximum operating pressure of 0.9 MPa, the push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf (5027 N).
No. The SC80X630TC is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is exhausted or the directional valve centres, the piston will drift. For load holding, add a pilot-operated check valve or an external rod brake.
