About the Airtac SC100 Standard Cylinder SC100X840S
The SC100X840S is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa and up to 7068 N at the maximum operating pressure of 0.9 MPa. With an 840 mm stroke and a 25 mm diameter piston rod, it is well-suited for medium-to-long linear movements in material handling and automation. The built-in magnet allows direct mounting of CMSG, DMSG, or EMSG sensors for reliable end-of-stroke detection.
This model features a 100 mm bore, PT1/2 port threads, and a 29 mm adjustable air cushion to decelerate the piston smoothly at the end of travel. The body length A is 188 mm, resulting in a total extended length of approximately 1028 mm. As a genuine AirTAC SC tie-rod cylinder, it offers a compact, serviceable design that is shorter than an equivalent ISO 15552 cylinder.

Where the Airtac SC100 Standard Cylinder SC100X840S Is Used
Long-Stroke Part Transfer
Moves components or pallets across an 840 mm span between conveyor lines or workstations, with magnetic sensors confirming full extension and retraction for interlocking logic.
Automated Press Feed
Pushes sheet material or blanks into a stamping press or CNC machine with 3927 N of force at standard line pressure, using the adjustable cushion to manage the impact at the end of the feed stroke.
Bin Diverter Gate
Actuates a large diverter chute in a gravity-fed sortation system, holding position under live pressure to route items, with the magnet sensor verifying the gate is fully open or closed.
Is the Airtac SC100 Standard Cylinder SC100X840S the Right Cylinder?
Choose the SC100 bore when your application requires a push force between 3927 N and 7068 N, a range that sits between the smaller SC80 (2513 N at 0.5 MPa) and the larger SC125 (6136 N at 0.5 MPa). For this 840 mm stroke, carefully evaluate side-loading conditions; a long, unsupported 25 mm rod is susceptible to bending under lateral forces. An external linear guide or a guided cylinder configuration is strongly recommended to protect the rod bearing and ensure consistent, long-life operation.
For a direct replacement, match five key specifications: 100 mm bore, 840 mm stroke, PT1/2 port thread, the built-in magnet (-S suffix), and the basic mounting configuration. This ensures the new unit will fit existing sensor brackets, port fittings, and mounting points without modification.
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 SC100X840S FAQ
At the standard 0.5 MPa operating pressure, the cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf.
No. The SC100X840S is a double-acting cylinder that requires continuous air pressure to maintain its position. If pressure is lost, exhausted, or the directional valve is centered, the piston will drift or the load will drop. For load-holding without live pressure, you must add an external mechanical lock, a rod brake, or a pilot-operated check valve.
