About the Airtac SC80 Standard Cylinder SC80X850SH
The AirTAC SC80X850SH is a double-acting single-rod pneumatic cylinder delivering 2513 N push force at 0.5 MPa and 4523 N at the 0.9 MPa maximum operating pressure. With an 850 mm stroke and a 25 mm diameter rod, it handles mid-range automation tasks requiring extended reach.
This model includes a built-in magnet (S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and Viton seals (H suffix) that shift the operating range to 0–150 °C for hot environments. The body length A is 182 mm, and the 28 mm adjustable air cushion at each end decelerates the piston smoothly at end-of-stroke.

Where the Airtac SC80 Standard Cylinder SC80X850SH Is Used
Foundry & Heat Treatment
Viton seals permit reliable actuation of dampers, pushers, or door mechanisms inside furnaces and ovens where ambient temperatures reach up to 150 °C.
Long-Reach Sorting Gate
The 850 mm stroke paired with 2513 N at 0.5 MPa provides ample reach and force to divert medium-weight packages or components on wide conveyor lines.
Hot Press Unloading
Withstands residual heat in composite or laminate press unloading stations. The magnetic piston allows end-of-stroke confirmation via barrel-mounted sensors in automated cells.
Is the Airtac SC80 Standard Cylinder SC80X850SH the Right Cylinder?
Choose the SC80 bore when your application needs around 2513 N at 0.5 MPa; stepping down to SC63 delivers 1559 N, while stepping up to SC100 provides 3927 N. This 850 mm stroke is within the 1500 mm maximum standard stroke for bore 80. For strokes of 300 mm or more, be mindful of side loading—the 25 mm rod may bend under off-axis forces; use an external guide rail or switch to a guided cylinder if side load is present. For a direct replacement, match bore (80 mm), stroke (850 mm), PT port thread, the S magnet option for sensors, and the H Viton seal specification.
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 SC80X850SH FAQ
At 0.5 MPa, the push force is 2513 N and pull force is 2268 N. At 0.7 MPa, push force reaches 3518 N. The maximum theoretical force at 1.0 MPa is 513 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length (A=182 mm) than an ISO 15552 cylinder of the same bore. It is not dimensionally interchangeable. Replace only with another AirTAC SC80 tie-rod cylinder matching the stroke, PT ports, magnet option, and Viton seals.
