About the Airtac SC50 Standard Cylinder SC50X50S
The AirTAC SC50X50S is a double-acting tie-rod cylinder with a 50 mm bore and a 50 mm standard stroke, factory-equipped with a built-in magnet (-S suffix). At 0.5 MPa air pressure it generates 982 N pushing force and 825 N pulling force, making it a capable mid-range actuator for short linear moves.
This model uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion (21 mm length) decelerates the piston quietly at end-of-stroke. The integrated magnet allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for non-contact position sensing.

Where the Airtac SC50 Standard Cylinder SC50X50S Is Used
Sensor-Ready Clamping
The built-in magnet enables end-of-stroke confirmation via CMSG/DMSG sensors, ideal for automated workholding fixtures where clamp/unclamp status must be verified by the PLC.
Short-Stroke Part Stops
With 50 mm of travel and 982 N of push force, this cylinder works well as a pneumatic part stop on conveyor lines, halting totes or small pallets for pick-and-place operations.
Compact Press-Fit Assembly
The 50 mm bore provides sufficient force for light press-fit or staking tasks in benchtop assembly cells, especially where magnetic piston sensing is needed for cycle counting.
Is the Airtac SC50 Standard Cylinder SC50X50S the Right Cylinder?
Choose the SC50 bore when your load requires roughly 980 N of push force at standard plant pressure. If you need more force, stepping up to the SC63 delivers 1559 N push at 0.5 MPa; for a lighter, more compact solution the SC40 provides 628 N. All SC cylinders share the same tie-rod architecture, so replacement is straightforward when you match bore, stroke, PT1/4 ports, and the -S magnet option.
For this 50 mm stroke, side loading is rarely a concern, but always align the rod with the load axis. If your application involves off-axis forces, consider an external guide rail or a guided cylinder to protect the rod bearing from premature wear.
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 SC50X50S FAQ
At 0.5 MPa (5 bar) the cylinder produces 982 N extending (push) and 825 N retracting (pull). At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical force at 1.0 MPa is 200 kgf.
Yes, provided the bore is 50 mm, the port thread is PT1/4, and the mounting style matches. The -S magnet option must also be present on the replacement if you use barrel-mounted sensors. Always verify the stroke, as a different stroke changes the overall extended length (body length 150 mm + stroke).
