About the Airtac SC100 Standard Cylinder SC100X420S
The SC100X420S 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 a 100 mm bore and 420 mm stroke, it features a 25 mm diameter piston rod, M20x1.5 rod thread, and PT1/2 ports. The built-in magnet (denoted by the -S suffix) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for reliable end-of-stroke detection.
This tie-rod cylinder is part of the AirTAC SC series, designed with a compact body length (A=188 mm) that is shorter than a typical ISO 15552 profile. The adjustable pneumatic cushion (29 mm length) decelerates the piston smoothly at each end, reducing impact and noise. The total extended length is approximately 608 mm, making it suitable for medium-stroke clamping, pressing, and material-handling tasks where position feedback is required.

Where the Airtac SC100 Standard Cylinder SC100X420S Is Used
Conveyor Sorting Gates
The 420 mm stroke and 3927 N push force at 0.5 MPa actuate heavy diverter gates in parcel and pallet conveyor systems. The built-in magnet provides sensor feedback to confirm gate position, ensuring reliable sortation.
Automated Pressing & Clamping
Delivers up to 7068 N of clamping force at 0.9 MPa for holding large workpieces during welding or assembly. The adjustable cushion protects tooling at the end of the 420 mm stroke, while the -S magnet signals clamp engagement.
Pallet Lift & Transfer
Pushes or lifts heavy pallets in transfer stations with a 3927 N force at standard line pressure. The tie-rod construction handles demanding industrial environments, and the magnetic piston enables easy integration of position sensors for automated storage systems.
Is the Airtac SC100 Standard Cylinder SC100X420S the Right Cylinder?
For applications requiring less force, consider stepping down to an 80 mm bore (2513 N at 0.5 MPa), while a 125 mm bore (6136 N at 0.5 MPa) offers a significant power increase if the 3927 N output is insufficient. This 420 mm stroke model exceeds 300 mm, so side-load management is critical—always guide the load externally with rails or rods to prevent bending stress on the 25 mm piston rod and premature bearing wear. When replacing an existing cylinder, match five key points: 100 mm bore, 420 mm stroke, PT1/2 port thread, the built-in magnet (-S) for sensor compatibility, and the basic (no bracket) mounting style.
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 SC100X420S 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. The -S suffix in the model code SC100X420S indicates a built-in magnet in the piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel to detect piston position without additional brackets.
