About the Airtac SC80 Standard Cylinder SC80X675STC
The AirTAC SC80X675STC is a double-acting tie-rod cylinder delivering a substantial 2513 N push force at 0.5 MPa, scaling up to 4523 N at the maximum operating pressure of 0.9 MPa. With an 80 mm bore and a 25 mm diameter piston rod, this model is built for demanding mid-range industrial tasks. The 675 mm stroke is well within the 1500 mm maximum standard stroke for this bore, ensuring standard lead times.
This configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, and a centre trunnion mount (TC) supplied with the TCM1 bracket, allowing the cylinder to pivot for swinging loads. The body length A is 182 mm, giving a total extended length of approximately 857 mm. It operates on 40 µm filtered air with an adjustable pneumatic cushion at both ends to decelerate the piston smoothly.

Where the Airtac SC80 Standard Cylinder SC80X675STC Is Used
Part Transfer & Sorting
The 675 mm stroke and pivoting trunnion mount make this cylinder ideal for transferring parts between conveyor lines or sorting gates, where the body needs to swing through an arc.
Clamping & Riveting
With 4523 N of force at 0.9 MPa, this unit provides powerful, controlled clamping for assembly fixtures, riveting stations, or light press-fit operations.
Hopper Gate Actuation
The centre trunnion mount and long stroke suit material handling gates or diverter chutes, allowing the cylinder to pivot as it opens and closes a heavy hopper door.
Is the Airtac SC80 Standard Cylinder SC80X675STC the Right Cylinder?
Select the SC80 bore when your application requires a push force between the 1767 N of the SC63 and the 3927 N of the SC100 at 0.5 MPa. For this 675 mm stroke, the 25 mm rod provides good column strength, but any significant side loading requires an external guide or a guided cylinder to prevent rod bearing damage and bending. The centre trunnion mount is ideal for applications where the cylinder body needs to pivot during its stroke.
For a direct replacement, match these five points exactly: 80 mm bore, 675 mm stroke, PT port thread, centre trunnion (TC) mounting accessory, and the built-in magnet for sensors. This is a genuine AirTAC SC tie-rod cylinder, which is shorter than a comparable ISO 15552 profile cylinder and is not dimensionally interchangeable with them.
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 SC80X675STC FAQ
At 0.7 MPa (7 bar), the theoretical push force on the piston is 3518 N. The pull force on the rod side is 2268 N, accounting for the area reduction from the 25 mm rod.
No. The SC80X675STC is a double-acting cylinder and will not hold position if pressure is exhausted or lost. The adjustable air cushion only decelerates the piston at stroke end; it is not a locking or holding brake. For load holding, you must add a pilot-operated check valve or an external mechanical rod lock.
