About the Airtac SC50 Standard Cylinder SC50X5S
The SC50X5S is a compact-stroke variant of the AirTAC SC tie-rod cylinder, delivering 982 N of push force at 0.5 MPa from its 50 mm bore. With a 20 mm diameter piston rod and a body length A of just 150 mm, this model is built for short, precise positioning moves where space is tight.
This unit includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for reliable end-of-stroke detection. The standard TPU seals provide a -20 to +70 °C operating range, and the 21 mm adjustable air cushion at each end helps manage end-of-stroke impact even on rapid short cycles.

Where the Airtac SC50 Standard Cylinder SC50X5S Is Used
Short-Stroke Clamping
The 5 mm stroke and 982 N push force make this ideal for compact pneumatic clamping fixtures in CNC machining or assembly cells, where a quick, repeatable grip is needed.
Knife-Edge Actuation
Provides a clean, short linear push for actuating cutting blades or shearing mechanisms in packaging and converting machinery, with sensor feedback confirming each cycle.
Part Stops & Diverters
Used as a pneumatic stop gate on light-duty conveyors. The 5 mm stroke is enough to pop up a stop pin, and the magnetic piston lets a sensor verify the retracted or extended position.
Is the Airtac SC50 Standard Cylinder SC50X5S the Right Cylinder?
For applications needing slightly more force, the 63 mm bore SC63 series offers 1559 N push at 0.5 MPa. If a lower force is acceptable, the 40 mm bore provides 628 N. This 5 mm stroke is well within the 1200 mm maximum standard stroke for the 50 mm bore.
When replacing an existing cylinder, match five points: 50 mm bore, 5 mm stroke, PT1/4 port thread, the built-in magnet for sensor mounting, and the basic (no bracket) mounting style. The SC series is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC50 Standard Cylinder SC50X5S FAQ
At 0.5 MPa (approx. 73 psi), the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The -S suffix in the model code means this cylinder has a built-in magnet on the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rods to detect piston position without any additional brackets.
