About the Airtac SC100 Standard Cylinder SC100X85
The SC100X85 is a double-acting pneumatic cylinder delivering a substantial 3927 N of push force at 0.5 MPa, making it a workhorse for medium-to-heavy industrial tasks. With an 85 mm stroke and a 25 mm diameter piston rod, this model provides a compact yet powerful linear motion solution where space is constrained but force demands are high.
Built on a robust tie-rod design, the SC100X85 features PT1/2 ports and an adjustable air cushion to decelerate the piston smoothly at the end of its travel. Its body length A is 188 mm, and the total extended length is approximately 273 mm. The standard TPU seals ensure reliable operation within a temperature range of -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X85 Is Used
Material Stops and Gates
The 3927 N push force at 0.5 MPa is ideal for actuating heavy-duty stops or diverting gates on conveyor lines, reliably halting or redirecting pallets and large packages.
Press and Clamping Fixtures
Delivers a powerful 7068 N of clamping force at 0.9 MPa, making it suitable for holding workpieces securely during welding, assembly, or machining operations.
Bin and Hopper Actuation
Provides the high breakaway force needed to open sticky slide gates on bulk material bins or hoppers, ensuring consistent flow control in processing plants.
Is the Airtac SC100 Standard Cylinder SC100X85 the Right Cylinder?
For applications needing more force, stepping up to the SC125 bore provides 6136 N of push force at 0.5 MPa. If a lighter, more compact solution is acceptable, the SC80 bore delivers 2513 N. When replacing this cylinder, ensure a 5-point match: 100 mm bore, 85 mm stroke, PT1/2 port thread, basic mounting (no accessories), and no built-in magnet.
At an 85 mm stroke, the rod is well-supported within the bearing, but for any future application with a stroke of 300 mm or more, external guides are strongly recommended to protect the rod bearing from side-load bending moments.
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 SC100 Standard Cylinder SC100X85 FAQ
At the standard 0.5 MPa operating pressure, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 7068 N.
No. The SC series is a tie-rod cylinder that is shorter than a comparable ISO 15552 profile cylinder. It is a direct dimensional match only for another AirTAC SC100 tie-rod cylinder with the same stroke, port thread, and mounting configuration.
