About the Airtac SC50 Standard Cylinder SC50X280S
The AirTAC SC50X280S is a double-acting single-rod pneumatic cylinder with a 50 mm bore and 280 mm stroke, delivering a push force of 982 N at 0.5 MPa (1767 N at 0.9 MPa). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range linear tasks.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for contactless position sensing. The body length A is 150 mm, giving a total extended length of approximately 430 mm, and it operates on filtered air from 0.15–1.0 MPa at -20 to +70 °C with standard TPU seals.

Where the Airtac SC50 Standard Cylinder SC50X280S Is Used
Package Sorting Gate
The 280 mm stroke and 982 N push force at 0.5 MPa reliably divert medium-weight cartons on conveyor lines. The built-in magnet enables sensor-based end-of-stroke confirmation for high-cycle sortation.
Clamping & Fixturing
Delivers consistent clamping force for woodworking or light metalworking jigs. The adjustable cushion protects the fixture from impact shock, while CMSG sensors verify clamp engagement before a cycle starts.
Automated Lift-Assist
Used in material handling for pushing bins or totes onto gravity rollers. The 20 mm rod resists buckling at this stroke length when the load is guided, and the tie-rod construction simplifies maintenance access.
Is the Airtac SC50 Standard Cylinder SC50X280S the Right Cylinder?
For applications needing slightly more force, stepping up to the 63 mm bore (SC63) provides 1559 N at 0.5 MPa, while the 40 mm bore (SC40) offers 628 N if a lighter, more compact unit is preferred. At 280 mm stroke, side-load forces are manageable, but always align the rod with the load axis and consider an external guide if off-axis forces are present.
To ensure a drop-in replacement, match five points exactly: 50 mm bore, 280 mm stroke, PT port thread, basic mounting (no bracket), and the built-in magnet (-S). This SC series is a tie-rod design, shorter than ISO 15552 cylinders, so dimensional interchangeability is limited to other AirTAC SC tie-rod units of the same 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 SC50X280S FAQ
At the standard operating pressure of 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, the push force reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
Yes. The -S suffix indicates a built-in magnet in the piston, which is specifically designed for mounting AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder's tie-rod barrel for non-contact position detection.
