About the Airtac SC50 Standard Cylinder SC50X130S
The SC50X130S is a 50 mm bore, 130 mm stroke double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range linear tasks.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for precise end-of-stroke or mid-stroke position sensing. The standard PT1/4 port and M16x1.5 rod thread make it straightforward to plumb and connect.

Where the Airtac SC50 Standard Cylinder SC50X130S Is Used
Package Diverter
Pushes cartons off a belt at 0.5-0.7 MPa. The built-in magnet confirms full extension and retraction for reliable sortation counts.
Clamping Fixture
Holds workpieces during machining or assembly. Sensor feedback from the -S magnet prevents cycle start until the part is securely clamped.
Lift-Gate Actuator
Raises and lowers a small gate or stop on a gravity conveyor. Position sensors integrated via the barrel magnet ensure the gate is fully open or closed.
Is the Airtac SC50 Standard Cylinder SC50X130S the Right Cylinder?
For higher force, step up to the 63 mm bore (1559 N at 0.5 MPa); for a lighter, more compact actuator, the 40 mm bore offers 628 N. At 130 mm stroke the rod is well-supported, but always avoid direct side loads—use an external guide or linear rail if lateral forces are present. When replacing an existing cylinder, match five points: 50 mm bore, 130 mm stroke, PT1/4 port thread, the built-in magnet for sensors, and the basic (no bracket) mounting configuration.
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 SC50X130S FAQ
At 0.5 MPa the push force is 982 N and pull force is 825 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The -S suffix means a magnet is built into the piston, so CMSG, DMSG, or EMSG sensors can be clamped onto the tie-rod barrel to detect piston position without external brackets.
