About the Airtac SC50 Standard Cylinder SC50X585S
The AirTAC SC50X585S is a double-acting tie-rod cylinder with a 50 mm bore and a 585 mm stroke, pre-configured with a built-in magnet for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors. Operating on filtered air at 0.15–1.0 MPa, it generates a push force of 982 N at 0.5 MPa and up to 1,767 N at 0.9 MPa, making it a robust mid-range actuator for automated lines.
This model uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The adjustable air cushion at each end is 21 mm long, and the body length A is 150 mm, giving a total extended length of approximately 735 mm. The standard TPU seals suit ambient temperatures from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X585S Is Used
Part Transfer & Sorting
The 585 mm stroke and sensor-ready design make it ideal for diverting or transferring parts between conveyor lanes, where end-of-stroke confirmation is required for cycle safety.
Clamping & Assembly Fixtures
Delivers 1,767 N of clamping force at 0.9 MPa, suitable for holding workpieces in welding or assembly jigs. The built-in magnet allows position sensing to confirm clamp engagement.
Packaging & Palletizing
Used in case erectors or pallet layer forming, the long 585 mm stroke pushes cartons or slip sheets into position with consistent force, while sensors verify full extension and retraction.
Is the Airtac SC50 Standard Cylinder SC50X585S the Right Cylinder?
For applications needing slightly less force, the 40 mm bore SC40 series provides 628 N of push at 0.5 MPa. If higher force is required, stepping up to the 63 mm bore delivers 1,559 N at the same pressure. At a 585 mm stroke, ensure the rod is not subjected to significant side loading; an external linear guide or rod support should be used to prevent bending and premature bearing wear.
When replacing an existing cylinder, match five key points: 50 mm bore, 585 mm stroke, PT port thread, the built-in magnet (-S suffix), and the basic mounting style. This tie-rod cylinder is dimensionally shorter than an ISO 15552 profile, so it is a direct fit only for another AirTAC SC series cylinder or a tie-rod design with identical mounting dimensions.
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 SC50X585S FAQ
At the standard operating pressure of 0.5 MPa, the cylinder provides 982 N pushing force and 825 N pulling force. At the maximum operating pressure of 0.9 MPa, the push force increases to 1,767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
Yes. The -S suffix in the model code SC50X585S indicates a built-in magnet in the piston. This allows AirTAC CMSG, DMSG, or EMSG series sensors to be clamped directly onto the barrel tie-rods for non-contact position sensing without any additional brackets.
