About the Airtac SC50 Standard Cylinder SC50X42
The SC50X42 is a compact double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a push force of 982 N at 0.5 MPa. With a 42 mm stroke and a 20 mm diameter piston rod, it suits short-throw clamping, ejecting, and pressing tasks where space is limited.
The cylinder body length A is 150 mm, giving a total extended length of approximately 192 mm. It features an adjustable air cushion (21 mm length) at both ends to decelerate the piston smoothly, reducing end-of-stroke impact. PT1/4 ports and an M16x1.5 rod thread are standard.

Where the Airtac SC50 Standard Cylinder SC50X42 Is Used
Short-Stroke Clamping
The 42 mm stroke and 982 N force at 0.5 MPa make it ideal for part clamping in CNC fixtures and welding jigs, where a rapid, firm hold is needed in a compact envelope.
Automated Ejection
Delivers a crisp, repeatable push to eject small components from injection molds or stamping dies, with the adjustable cushion protecting tooling from shock.
Diverter Gate Actuation
Provides the short, decisive motion required to flip a diverter gate on a packaging or sorting conveyor line, operating reliably on standard filtered plant air.
Is the Airtac SC50 Standard Cylinder SC50X42 the Right Cylinder?
For applications needing slightly more force, the 63 mm bore SC63 series provides 1559 N push at 0.5 MPa. If a smaller footprint is required, the 40 mm bore SC40 delivers 628 N. The 42 mm stroke is well within the standard range for this bore.
When replacing an existing cylinder, match five key points: 50 mm bore, 42 mm stroke, PT1/4 port thread, the specific mounting accessory (this model is basic, without brackets), and the magnet option (this model has no built-in magnet). The SC 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 SC50X42 FAQ
At 0.7 MPa operating pressure, the SC50X42 cylinder produces a theoretical push force of 1374 N. The maximum push force at the 0.9 MPa operating limit is 1767 N.
This specific model code (SC50X42) does not include the -S suffix for a built-in magnet. To use CMSG or DMSG sensors, order the SC50X42-S variant, which has a magnetized piston band that allows sensors to clamp directly onto the barrel.
