About the Airtac SC50 Standard Cylinder SC50X350SH
The SC50X350SH is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. Its 350 mm stroke is well within the 1200 mm maximum standard stroke for the 50 mm bore, making it a standard-catalogue size. The 20 mm diameter piston rod and 21 mm adjustable air cushion at each end ensure smooth deceleration of the moving mass.
This variant includes a built-in magnet (-S suffix) for direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the tie-rod barrel, eliminating the need for external switch brackets. The -H suffix specifies Viton (FKM) seals, shifting the operating temperature range from the standard -20 to +70 °C up to 0 to +150 °C, suitable for hot or chemically aggressive environments. Ports are standard PT1/4.

Where the Airtac SC50 Standard Cylinder SC50X350SH Is Used
High-Temperature Actuation
Viton seals enable reliable operation in autoclaves, drying ovens, or foundry equipment where ambient temperatures reach up to 150°C, with 1767 N of force for pressing or clamping.
Sensor-Monitored Part Transfer
The built-in magnet allows CMSG/DMSG sensors to confirm end-of-stroke position, providing closed-loop feedback for a 350 mm pick-and-place or diverting station on a packaging line.
Hot-Melt Glue or Welding Fixture
Delivers consistent 982 N clamping force at standard plant pressure in elevated-temperature zones, with the adjustable cushion protecting the tooling from impact damage at cycle end.
Is the Airtac SC50 Standard Cylinder SC50X350SH the Right Cylinder?
Choose the SC50 bore when your application requires between 982 N (push at 0.5 MPa) and 1767 N (push at 0.9 MPa). If you need more force, stepping up to the SC63 bore provides 1559 N at 0.5 MPa. For a lower force requirement, the SC40 bore delivers 628 N at 0.5 MPa. With a 350 mm stroke, ensure the load is guided and side forces are minimal; long unsupported strokes on the 20 mm rod can create a bending moment. For side-load applications, use an external guide or switch to a guided cylinder.
For direct replacement, match these five points: 50 mm bore, 350 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the Viton seal material. This SC model is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC50X350SH FAQ
At the standard 0.5 MPa operating pressure, the cylinder provides 982 N extending (push) and 825 N retracting (pull). At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It is a direct replacement only for another AirTAC SC tie-rod cylinder matching the 50 mm bore, 350 mm stroke, PT1/4 ports, built-in magnet, and Viton seals.
