About the Airtac SC50 Standard Cylinder SC50X260S
The AirTAC SC50X260S is a double-acting single-rod pneumatic cylinder with a 50 mm bore and 260 mm stroke, factory-equipped with a built-in magnet (-S suffix) so CMSG, DMSG, or EMSG reed and solid-state sensors clamp directly onto the tie-rod barrel for contactless position sensing. At 0.5 MPa it delivers 982 N push force and 825 N pull force, rising to a maximum theoretical output of 200 kgf at 1.0 MPa.
This model uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 port connections. The adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly, while the compact tie-rod body (body length A = 150 mm) keeps the overall extended length to approximately 410 mm. Standard TPU seals give an operating range of -20 to +70 °C with filtered air at 0.15–1.0 MPa.

Where the Airtac SC50 Standard Cylinder SC50X260S Is Used
Package Diverter Gate
The 260 mm stroke pushes a diverter flap across a conveyor line. The built-in magnet allows two CMSG sensors to confirm gate-open and gate-closed positions for the PLC.
Clamp & Fixture Actuation
Delivers 982 N of clamping force at 0.5 MPa to hold workpieces during light machining or assembly. The sensor magnet confirms the clamp is fully engaged before the cycle starts.
Bin Tipping Station
Extends to tilt a small parts bin for operator access. The adjustable cushion prevents a hard stop at full tilt, and the magnetic piston lets the control system verify full extension.
Is the Airtac SC50 Standard Cylinder SC50X260S the Right Cylinder?
Choose the SC50 bore when your application needs roughly 1000 N of push force at standard plant pressure; if you need more force, stepping up to the SC63 delivers 1559 N at the same 0.5 MPa, while the SC40 provides 628 N for lighter, faster-cycling loads. The built-in magnet on this -S model lets you add CMSG/DMSG sensors without external brackets, simplifying stroke-end confirmation or mid-stroke sensing.
For a 260 mm stroke, ensure the load is guided and side forces are minimal—an unsupported 20 mm rod at this extension can bend under off-axis loads. If side load is unavoidable, use an external guide rail or a guided cylinder. When replacing an existing unit, match all five points: 50 mm bore, 260 mm stroke, PT1/4 ports, the built-in magnet (-S), and the basic mounting configuration.
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 SC50X260S 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 means a magnet is built into the piston, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clip directly onto the tie-rod barrel. No external mounting brackets or target flags are required.
