About the Airtac SC100 Standard Cylinder SC100X70S
The SC100X70S is a 100 mm bore, 70 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It delivers a push force of 3927 N at 0.5 MPa and can reach 7068 N at the maximum operating pressure of 0.9 MPa, making it a strong actuator for medium-stroke clamping and pressing tasks.
This model includes the -S suffix, indicating a built-in magnet that allows CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly onto the barrel for contactless position sensing. The rod diameter is 25 mm with an M20x1.5 thread, and the adjustable air cushion at each end is 29 mm long, providing smooth deceleration for the 70 mm stroke.

Where the Airtac SC100 Standard Cylinder SC100X70S Is Used
Automated Clamping with Position Feedback
The built-in magnet allows CMSG/DMSG sensors to confirm clamp closure, making this cylinder ideal for automated welding or assembly fixtures that require a position-verified signal before the next cycle starts.
Product Stop and Gate Actuation
With 3927 N of force at 0.5 MPa, the SC100X70S can reliably raise and lower heavy-duty product stops or diverting gates on conveyor lines, with sensor feedback confirming the gate's open or closed state.
Press-Fit and Staking Operations
The 70 mm stroke and high force output are well-suited for short-travel press-fit, staking, or riveting heads in automated production cells, where end-of-stroke sensing ensures the operation is complete.
Is the Airtac SC100 Standard Cylinder SC100X70S the Right Cylinder?
Choose the SC100 when your application needs around 3927 N of force at standard plant pressure. If you can work with less force, stepping down to an 80 mm bore reduces the push force to 2513 N at 0.5 MPa and saves space. For a higher force requirement, the 125 mm bore offers 6136 N.
To ensure a straightforward replacement, match five key points: 100 mm bore, 70 mm stroke, PT port thread, the built-in magnet (-S) for sensor compatibility, and the basic mounting style. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.

- ✓ 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 SC100X70S FAQ
At 0.7 MPa operating pressure, the push force on the extend stroke is 5497 N. The pull force on the retract stroke at the same pressure is 3681 N.
Yes. The -S suffix in the model code means a magnet is built into the piston. This allows you to clamp AirTAC CMSG, DMSG, or EMSG sensors directly onto the cylinder barrel for non-contact position detection without any modification.
