About the Airtac SC50 Standard Cylinder SC50X925S
The AirTAC SC50X925S is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (up to 1767 N at 0.9 MPa). Its 50 mm bore and 925 mm stroke make it a strong candidate for medium-duty linear transfer and lifting tasks where a long reach is required.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly on the barrel for contactless position sensing. The 20 mm diameter piston rod and 21 mm adjustable air cushion provide smooth deceleration, while the PT1/4 port thread ensures straightforward pneumatic connections.

Where the Airtac SC50 Standard Cylinder SC50X925S Is Used
Long-Reach Part Transfer
Moves components across wide conveyor gaps or indexing stations, with the 925 mm stroke covering extended transfer distances.
Vertical Lift Gate Actuation
Operates tall lift gates or hopper doors, using the 1767 N maximum force to raise and lower panels reliably.
Automated Assembly Pusher
Pushes parts into fixtures or assembly nests, with magnetic sensors confirming full extension and retraction at each cycle.
Is the Airtac SC50 Standard Cylinder SC50X925S the Right Cylinder?
For applications needing slightly less force, stepping down to a 32 mm bore reduces push force to 402 N at 0.5 MPa; for heavier loads, the 63 mm bore provides 1559 N. With a 925 mm stroke, the unsupported rod length is significant—external guides or a guided cylinder should be considered to prevent rod bending under side load. When replacing, match bore, stroke, PT port thread, the basic mounting configuration, and the integrated magnet (-S) to ensure sensor compatibility.
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 SC50X925S FAQ
At 0.5 MPa, the push force is 982 N and the 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 indicates a built-in magnet, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors can be clamped directly onto the barrel for non-contact position detection.
