About the Airtac SC80 Standard Cylinder SC80X630STC
The AirTAC SC80X630STC is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa, scaling up to 4523 N at 0.9 MPa. Its 630 mm stroke suits medium-reach clamping, pressing, and material transfer tasks. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for reliable end-of-stroke detection.
This model features a 25 mm diameter piston rod with M20x1.5 threads and a 28 mm adjustable air cushion at each end to decelerate the load smoothly. The centre trunnion mount (TC) ships with the TCM1 bracket, allowing the cylinder to pivot and handle swinging loads without side-loading the rod. Ports are PT1/8.

Where the Airtac SC80 Standard Cylinder SC80X630STC Is Used
Conveyor Diverters
Pivoting gate or pusher arms on packaging lines, where the trunnion mount absorbs the swinging motion and sensors confirm the gate position.
Clamping Fixtures
Heavy-duty part clamping in machining centres, using the 4523 N force at 0.9 MPa to secure workpieces during milling or drilling operations.
Press Mechanisms
Light assembly presses for bearing insertion or riveting, where the adjustable cushion reduces impact at the end of the 630 mm stroke.
Is the Airtac SC80 Standard Cylinder SC80X630STC the Right Cylinder?
For higher force, step up to the SC100 bore providing 3927 N at 0.5 MPa; for a lighter, more compact option, the SC63 offers 1559 N. At 630 mm stroke, ensure the rod is supported against side loads—use external guides or linear rails to prevent bending of the 25 mm rod. To match this cylinder for replacement, verify five points: 80 mm bore, 630 mm stroke, PT port thread, centre trunnion (TC) mount with F-SC80TC bracket, and the built-in magnet (-S) for sensor compatibility.
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 SC80X630STC FAQ
At 0.5 MPa, the cylinder pushes with 2513 N; at 0.7 MPa, force is 3518 N; and at the maximum operating pressure of 0.9 MPa, it reaches 4523 N. Pull force is slightly lower due to the rod area, providing 2268 N at 0.5 MPa.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder. It is dimensionally interchangeable only with another AirTAC SC tie-rod cylinder of the same bore, stroke, and mounting configuration.
