About the Airtac SC50 Standard Cylinder SC50X180SH
The SC50X180SH is a double-acting pneumatic cylinder with a 50 mm bore and 180 mm stroke, delivering 982 N of push force at 0.5 MPa (up to 1767 N at 0.9 MPa). The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for reliable end-of-stroke detection.
This model is equipped with high-temperature Viton (FKM) seals, shifting the operating temperature range to 0–150 °C, making it suitable for autoclaves, foundries, and hot-process automation. The 20 mm diameter piston rod and 21 mm adjustable air cushion ensure smooth deceleration in a compact tie-rod body with a length A of 150 mm.

Where the Airtac SC50 Standard Cylinder SC50X180SH Is Used
High-Temperature Process Automation
With Viton seals rated for 0–150 °C, this cylinder is ideal for actuating dampers, gates, or clamps in autoclaves, drying ovens, and heat-treatment lines where standard seals would degrade.
Sensor-Monitored Assembly Fixtures
The built-in magnet enables CMSG/DMSG sensors to confirm clamp/unclamp status in automated assembly cells, preventing cycle-start errors and ensuring part presence verification.
Hot-Material Sorting & Diverting
Deploy the SC50X180SH on conveyor diverters handling hot glass, ceramics, or baked goods. The 180 mm stroke provides sufficient reach for pusher arms, while the Viton seals withstand radiated heat.
Is the Airtac SC50 Standard Cylinder SC50X180SH the Right Cylinder?
For applications requiring more force, consider stepping up to the 63 mm bore (1559 N at 0.5 MPa). If a lower force profile is acceptable, the 40 mm bore (628 N at 0.5 MPa) offers a smaller footprint. This 50 mm bore cylinder uses a 20 mm rod; for strokes over 300 mm or any side-load condition, use an external guide or switch to a guided cylinder to prevent rod bearing damage.
To guarantee a drop-in replacement, match five key points: 50 mm bore, 180 mm stroke, PT port thread, the built-in magnet (-S suffix), and the basic mounting configuration. The Viton seal (-H suffix) must also be matched if the application runs above 70 °C.
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 SC50X180SH FAQ
At 0.5 MPa the cylinder pushes with 982 N and pulls with 825 N. 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 SC50X180SH is a double-acting cylinder and will drift or drop if pressure is lost or the valve is centered. To hold a position or load without live pressure, you must add a pilot-operated check valve, a rod lock, or an external mechanical brake.
