About the Airtac SC80 Standard Cylinder SC80X830S
The AirTAC SC80X830S is a double-acting single-rod pneumatic cylinder with an 80 mm bore and an 830 mm stroke, delivering a push force of 2513 N at 0.5 MPa (up to 4523 N at 0.9 MPa). The built-in magnet allows CMSG/DMSG/EMSG reed or solid-state sensors to clamp directly onto the tie-rod barrel for contactless position sensing.
This model uses a 25 mm diameter piston rod with an M20x1.5 male thread and PT3/8 ports. The adjustable air cushion (28 mm length) decelerates the piston at end-of-stroke, and the total body length A is 182 mm, giving an extended length of approximately 1012 mm. Operating temperature range is -20 to +70 °C with standard TPU seals.

Where the Airtac SC80 Standard Cylinder SC80X830S Is Used
Long-Reach Part Transfer
The 830 mm stroke and 2513 N push force at 0.5 MPa move heavy components between distant conveyor stations, with the built-in magnet enabling end-of-stroke sensor confirmation.
Palletising Pusher Arm
Pushes boxes or pallets across a wide accumulation table. The adjustable cushion absorbs impact energy at full extension, protecting the 25 mm rod and end cap.
Automated Welding Fixture Clamp
The 80 mm bore provides 4523 N of clamping force at 0.9 MPa for holding large weldments. The -S magnet allows sensor feedback to confirm the clamp is fully engaged before the welding cycle starts.
Is the Airtac SC80 Standard Cylinder SC80X830S the Right Cylinder?
Choose the SC80X830S when your application needs the 2513 N push force of an 80 mm bore at 0.5 MPa. If your load is lighter, stepping down to a 63 mm bore (1559 N at 0.5 MPa) saves space and air consumption; for heavier loads, the 100 mm bore provides 3927 N at the same pressure. Because the 830 mm stroke is long, ensure the rod is not subjected to side loads—use an external linear guide or a guided cylinder to prevent rod bending and premature bearing wear.
For a direct replacement, match five points: 80 mm bore, 830 mm stroke, PT3/8 port thread, the built-in magnet (-S suffix), and the basic (no bracket) mounting style. This is a genuine AirTAC SC tie-rod cylinder, not an ISO 15552 profile cylinder.
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 SC80X830S FAQ
At 0.7 MPa operating pressure, the theoretical push force is 3518 N and the pull force (retract) is 2268 N. At the maximum operating pressure of 0.9 MPa, push force reaches 4523 N.
Yes, an external guide or rod support is strongly recommended for an 830 mm stroke. The 25 mm rod can bend under side load at full extension. Mounting the cylinder body with LB foot brackets (F-SC80LB) and coupling the rod to a linear guide rail prevents bearing damage and ensures straight-line motion.
