About the Airtac SC50 Standard Cylinder SC50X210S
The AirTAC SC50X210S is a double-acting single-rod tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). Its 210 mm stroke is well within the 1200 mm maximum standard stroke for the 50 mm bore, making it a readily available configuration for medium-reach linear tasks.
The built-in magnet (-S suffix) allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for reliable end-of-stroke or mid-stroke position sensing. The 20 mm diameter piston rod and PT1/4 ports provide a robust connection for general automation, while the 21 mm adjustable air cushion decelerates the piston smoothly at both ends.

Where the Airtac SC50 Standard Cylinder SC50X210S Is Used
Package Diverting
The 210 mm stroke and 982 N push force at 0.5 MPa reliably divert cartons or totes on conveyor lines. The built-in magnet enables sensor feedback to confirm each divert cycle.
Clamping & Fixturing
Applies controlled clamping force up to 1767 N at 0.9 MPa for CNC fixtures or welding jigs. Magnetic sensors verify the clamp is fully engaged before the machine cycle starts.
Gate or Hopper Actuation
Operates slide gates on hoppers or chutes handling granular material. The adjustable cushion reduces end-of-stroke shock, and the magnet allows remote gate position monitoring.
Is the Airtac SC50 Standard Cylinder SC50X210S the Right Cylinder?
Choose the SC50 bore when your application needs roughly 982 N of force at standard plant pressure. If you need more force, stepping up to the 63 mm bore provides 1559 N at the same 0.5 MPa. For lighter, faster loads, the 40 mm bore offers 628 N. This 210 mm stroke model includes a magnet for sensor mounting; if your control system does not require position feedback, the non-magnet SC50X210 is a simpler alternative.
For a direct replacement, match five points: 50 mm bore, 210 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the basic (no bracket) mounting style. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC50 tie-rod units.
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 SC50X210S 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, the push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The SC series is a tie-rod cylinder that is shorter in overall length than a comparable ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552 mounts. Use it to replace another AirTAC SC50 tie-rod cylinder with the same stroke, port thread, and magnet option.
