About the Airtac SC80 Standard Cylinder SC80X875S
The SC80X875S is an AirTAC SC series double-acting tie-rod cylinder with an 80 mm bore and a long 875 mm stroke, factory-equipped with a built-in magnet (-S suffix) so CMSG/DMSG/EMSG sensors can clamp directly onto the barrel for rod-position feedback. At 0.5 MPa air pressure it generates 2513 N pushing force and 2268 N pulling force; at the maximum operating pressure of 0.9 MPa the push thrust reaches 4523 N, placing it in a robust mid-range force class.
This model uses a 25 mm diameter piston rod with M20x1.5 male knuckle threads and PT1/8 port threads. The adjustable pneumatic cushion at each end (28 mm cushion length) decelerates the piston smoothly, and the body length A is 182 mm, giving a total extended length of approximately 1057 mm. The standard TPU/NBR seals suit ambient temperatures from -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X875S Is Used
Long-Reach Part Transfer
The 875 mm stroke moves components between distant conveyor stations, with the magnetic piston enabling end-of-stroke confirmation via barrel-mounted sensors.
Automated Material Pusher
Delivers 2513 N at 0.5 MPa to push heavy bins or pallets off a main line onto a spur, using the adjustable cushion to protect the load at the end of travel.
Vertical Panel Lifter
Raises and lowers large panels in a framing jig; the built-in magnet allows mid-stroke position sensing for multi-height stopping points.
Is the Airtac SC80 Standard Cylinder SC80X875S the Right Cylinder?
Choose the SC80 bore when the 50 mm bore’s 982 N push at 0.5 MPa is insufficient; if you need more force still, the SC100 bore provides 3927 N at the same pressure. For this 875 mm stroke, the long unsupported piston rod is vulnerable to bending under side load—fit an external linear guide or switch to a guided cylinder if the load is not purely axial. To replace an existing cylinder, match five points exactly: 80 mm bore, 875 mm stroke, PT1/8 port thread, the built-in magnet (-S), and the basic (no bracket) mounting configuration.
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 SC80X875S FAQ
At 0.7 MPa the theoretical push force is 3518 N and the pull force on the rod side is 2268 N (the pull force value remains the same as at 0.5 MPa in the datasheet thrust table; confirm the 0.7 MPa pull figure from the full datasheet if needed).
Yes. The -S suffix means a magnet is built into the piston, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clip directly onto the tie-rod barrel to detect piston position without any modification.
