About the Airtac SC50 Standard Cylinder SC50X110SH
The AirTAC SC50X110SH is a double-acting tie-rod 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 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range automation tasks.
This specific model includes a built-in magnet (-S) for mounting CMSG/DMSG/EMSG sensors directly on the barrel, enabling precise end-of-stroke detection. The 'H' suffix designates Viton (FKM) seals, shifting the operating temperature range from the standard -20–+70 °C to 0–+150 °C, making it suitable for hot or chemically aggressive environments.

Where the Airtac SC50 Standard Cylinder SC50X110SH Is Used
High-Temperature Actuation
Viton seals allow this cylinder to operate reliably in ovens, autoclaves, and foundry equipment where ambient temperatures reach up to 150 °C, a condition standard seals cannot withstand.
Sensor-Controlled Sorting Gates
The built-in magnetic piston enables direct mounting of reed or solid-state sensors on the tie-rods, providing clean, contactless position feedback for diverting packages or parts on a conveyor line.
Chemical Process Valve Actuation
With FKM seals resistant to aggressive media and a robust 20 mm rod, this cylinder is ideal for automating ball or butterfly valves in chemical dosing and mixing systems.
Is the Airtac SC50 Standard Cylinder SC50X110SH the Right Cylinder?
For applications requiring more force, consider stepping up to the 63 mm bore SC63 series, which provides 1559 N at 0.5 MPa. If a shorter overall length is needed, the 40 mm bore SC40 offers 628 N at the same pressure. Always match the bore, 110 mm stroke, PT port thread, and ensure the replacement also has the -S magnet and high-temperature Viton seals.
With a 110 mm stroke, the rod is well-supported within the standard design envelope, but any side loading should be managed with an external guide to prevent premature rod bearing wear and ensure consistent cycle life.
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 SC50X110SH FAQ
At 0.7 MPa (7 bar), the theoretical push force is 1374 N. The pull force on the retract stroke is 825 N at the same pressure due to the area reduction from the 20 mm piston rod.
No. A standard SC50 uses TPU seals rated only for -20 to +70 °C. For applications running above 70 °C, you must use the -H Viton seal variant to prevent seal degradation and premature failure.
