About the Airtac SC50 Standard Cylinder SC50X16S
The SC50X16S is a short-stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering 982 N of push force at 0.5 MPa and up to 1767 N at the 0.9 MPa maximum operating pressure. Its 16 mm stroke is well within the standard range for the 50 mm bore, making it a stock-configuration actuator with a 20 mm diameter piston rod and M16x1.5 rod-end thread.
The built-in magnet (suffix -S) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for non-contact position sensing. With PT1/4 ports, a 21 mm adjustable air cushion at each end, and a compact 150 mm body length, this cylinder is ready for fast cycling in fixture and clamping applications.

Where the Airtac SC50 Standard Cylinder SC50X16S Is Used
Sensor-Monitored Clamping
The 16 mm stroke with built-in magnet enables precise end-of-stroke detection in automated workholding fixtures, confirming clamp/unclamp status at every cycle.
Short-Throw Part Stops
With 982 N at 0.5 MPa, the SC50X16S acts as a robust pneumatic stop on conveyor lines, halting totes or pallets with sensor feedback to the line controller.
Press-Fit & Assembly Tools
The compact 150 mm body and 1767 N peak force at 0.9 MPa suit benchtop assembly presses where stroke length is minimal but force repeatability is critical.
Is the Airtac SC50 Standard Cylinder SC50X16S the Right Cylinder?
For applications needing slightly more force at the same pressure, stepping up to the 63 mm bore provides 1559 N push at 0.5 MPa, while the 40 mm bore offers 628 N if a smaller envelope is preferred. The SC50X16S is a basic-mount cylinder; add an LB foot mount (F-SC50LB) for surface fixing or a TC centre trunnion (F-SC50TC) if the cylinder must pivot during operation.
When replacing an existing cylinder, match five points: 50 mm bore, 16 mm stroke, PT1/4 port thread, the built-in magnet (-S) for sensor compatibility, and the mounting style. The SC is a tie-rod design 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 SC50X16S FAQ
At 0.5 MPa supply pressure the cylinder produces 982 N extending (push) and 825 N retracting (pull). At the maximum operating pressure of 0.9 MPa, push force rises to 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The -S suffix indicates a built-in magnet on the piston, so CMSG, DMSG, or EMSG sensors clamp directly onto the tie-rod barrel without additional brackets or modifications.
