About the Airtac SC100 Standard Cylinder SC100X400SCB
The SC100X400SCB is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa). Its 100 mm bore and 400 mm stroke make it a workhorse for medium-to-heavy linear actuation tasks. The built-in magnet (-S suffix) allows CMSG/DMSG/EMSG sensors to clamp directly onto the tie-rod barrel for reliable end-of-stroke detection.
This model features a rear double clevis mount (CB suffix), supplied as the F-SC100CB accessory, which allows the cylinder to pivot freely at the cap end—ideal for articulating linkages. The 25 mm diameter piston rod and 29 mm adjustable air cushion at each end provide smooth deceleration. With a body length A of 188 mm, the total extended length is approximately 588 mm.

Where the Airtac SC100 Standard Cylinder SC100X400SCB Is Used
Clamping & Pressing
With 7068 N of force at 0.9 MPa, this cylinder provides ample power for pneumatic clamping fixtures, light assembly presses, and holding workpieces during machining or welding operations.
Pivoting Linkages
The rear double clevis mount (CB) allows the cylinder body to swing, making it suitable for actuating dump hoppers, chute gates, or any mechanism where the load path follows an arc.
Material Handling Gates
Use the SC100X400SCB to divert product on conveyor lines. The magnetic piston enables sensor feedback to confirm the gate is fully open or closed, integrating seamlessly with PLC control systems.
Is the Airtac SC100 Standard Cylinder SC100X400SCB the Right Cylinder?
Choose the SC100 bore when your application needs between 3927 N (push at 0.5 MPa) and 7068 N (push at 0.9 MPa). If you can accept a lower force of 2513 N at 0.5 MPa, stepping down to the SC80 bore saves space and air consumption. For a 400 mm stroke, ensure the rod is not subjected to significant side load; if lateral forces are present, add an external linear guide or switch to a guided cylinder to prevent rod bending and premature seal wear.
To replace an existing cylinder, match five points exactly: 100 mm bore, 400 mm stroke, PT port thread, the F-SC100CB rear double clevis mounting, and the -S magnetic piston for sensor compatibility. The SC is a tie-rod cylinder and is dimensionally shorter than ISO 15552 types, so it is not a direct drop-in for those profiles.
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 SC100X400SCB FAQ
At the standard operating pressure of 0.7 MPa, the theoretical push force is 5497 N and the pull force is 3681 N. The maximum push force at 0.9 MPa is 7068 N. Always apply a safety factor to these theoretical values for real-world dynamic loads.
No, the AirTAC SC series is a tie-rod cylinder and its overall body length (188 mm A-dimension) is shorter than a comparable ISO 15552 profile cylinder. The mounting interfaces and tie-rod dimensions also differ. It is a direct replacement only for another AirTAC SC100 tie-rod cylinder with matching stroke, PT ports, CB mount, and magnet.
