About the Airtac SC100 Standard Cylinder SC100X840SN
The SC100X840SN is a double-acting pneumatic cylinder delivering 3927 N of push force and 3681 N of pull force at 0.5 MPa. With an 840 mm stroke, this model is well-suited for long-reach material transfer or clamping operations. The 25 mm diameter piston rod and 29 mm adjustable air cushion provide smooth end-of-stroke deceleration, while the PT1/2 port ensures ample flow for the 100 mm bore.
This unit features a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG sensors along the tie-rod barrel for precise position feedback. The -N suffix specifies NBR (nitrile) seals, offering reliable sealing performance within the standard operating temperature range of -20 to +70 °C. As a genuine AirTAC SC series cylinder, it is a durable, non-ISO tie-rod design that is shorter than ISO 15552 alternatives.

Where the Airtac SC100 Standard Cylinder SC100X840SN Is Used
Long-Stroke Material Transfer
The 840 mm stroke and 3927 N push force efficiently move heavy bins or panels between conveyor lines, with the magnetic piston enabling end-of-travel sensor confirmation.
Automated Clamping Fixtures
Provides consistent, high-force clamping for large weldments or assemblies. The adjustable cushion minimizes vibration at the end of the 840 mm stroke, protecting the fixture.
Palletizing & Sorting Gates
Operates heavy diverter gates in logistics systems. The NBR seals and PT ports are compatible with standard industrial air prep, and the magnet supports mid-stroke sensing.
Is the Airtac SC100 Standard Cylinder SC100X840SN the Right Cylinder?
For applications requiring less force, consider stepping down to the 80 mm bore (2513 N at 0.5 MPa). If higher thrust is needed, the 125 mm bore provides 6136 N at the same pressure. Given the 840 mm stroke, ensure the load is guided externally to prevent excessive side-load bending moments on the 25 mm rod; for unsupported loads, a guided cylinder or external linear rail is recommended.
When replacing an existing cylinder, match five key points: 100 mm bore, 840 mm stroke, PT1/2 port thread, the built-in magnet for sensor compatibility, and the NBR seal material. This SC tie-rod cylinder is dimensionally interchangeable only with another AirTAC SC100 series unit of the same configuration.

- ✓ 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 SC100X840SN FAQ
At 0.5 MPa, 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. The theoretical maximum force at 1.0 MPa is 801 kgf.
Yes, for an 840 mm stroke on a 25 mm rod, external guides or a guided cylinder configuration are strongly recommended. Side loads or unsupported weight can cause rod deflection and premature bearing wear; the SC series does not include internal guidance to resist these bending moments.
