About the Airtac SC80 Standard Cylinder SC80X620STC
The SC80X620STC is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa and 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 mid-to-heavy industrial linear motion tasks requiring a long 620 mm stroke. The adjustable air cushion at each end, with a 28 mm cushion length, decelerates the piston smoothly to protect end caps and reduce noise.
This configuration includes a built-in magnet (-S suffix) that allows barrel-mounted CMSG, DMSG, or EMSG sensors to detect piston position without external brackets. The TC suffix specifies a centre trunnion mount, supplied with the TCM1 bracket (part code F-SC80TC), enabling the cylinder to pivot during operation. The body length A is 182 mm, making the total extended length approximately 802 mm. As a genuine AirTAC SC series tie-rod cylinder, it provides a compact, non-ISO 15552 form factor ideal for space-constrained machinery.

Where the Airtac SC80 Standard Cylinder SC80X620STC Is Used
Part Transfer & Indexing
The 620 mm stroke and centre trunnion mount allow this cylinder to pivot and push heavy pallets or components between conveyor lines, with sensor confirmation of full extension and retraction.
Clamping & Welding Fixtures
Delivers a strong, consistent 4523 N clamping force at 0.9 MPa for holding large weldments or machined parts. The trunnion mount lets the cylinder swing clear for easy part loading and unloading.
Bin Diverter Gates
Pivots a heavy diverter chute in a gravity-fed sorting system. The built-in magnet with CMSG sensors provides positive end-of-stroke feedback to the PLC, ensuring the gate is fully open or closed.
Is the Airtac SC80 Standard Cylinder SC80X620STC the Right Cylinder?
Choose the SC80 bore when your application needs between 2513 N (push at 0.5 MPa) and 4523 N (push at 0.9 MPa). If you require more force, step up to the SC100 bore, which provides 3927 N at 0.5 MPa. For a lighter, more compact solution, the SC63 bore offers 1559 N at 0.5 MPa. For this 620 mm stroke, carefully manage side loads: the 25 mm rod is long when extended, making it susceptible to bending under off-axis forces. Use an external guide rail or rod-alignment coupler to protect the rod bearing and seal. To replace this cylinder, match five points: 80 mm bore, 620 mm stroke, PT port thread, centre trunnion (TC) mounting, 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 SC80X620STC FAQ
At the standard 0.5 MPa operating pressure, the push force is 2513 N and the pull force is 2268 N (due to the 25 mm rod area). At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder of the same bore and stroke. It is not dimensionally interchangeable. Only replace with another AirTAC SC80 tie-rod cylinder matching the 620 mm stroke, PT ports, TC mount, and magnet option.
