About the Airtac SC50 Standard Cylinder SC50X160H
The SC50X160H is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, configured with a 50 mm bore and a 160 mm standard stroke. It generates a theoretical push force of 1767 N at the maximum operating pressure of 0.9 MPa, making it well-suited for medium-duty clamping and pressing tasks.
This model features the 'H' suffix, indicating high-temperature Viton (FKM) seals that shift the operating temperature range to 0 to +150 °C, ideal for autoclaves or foundry equipment. The 20 mm diameter piston rod provides robust resistance to bending, while the adjustable air cushion, with a 21 mm cushion length, decelerates the piston smoothly to reduce end-of-stroke impact.

Where the Airtac SC50 Standard Cylinder SC50X160H Is Used
High-Temperature Automation
With Viton seals rated for 0 to 150 °C, this cylinder is a direct fit for autoclave door actuation, hot stamping presses, and foundry mould handling where standard seals would degrade.
Hot Material Sorting
Deploy the SC50X160H on conveyor diverter gates or pushers handling hot products. The 50 mm bore provides 1374 N of push at 0.7 MPa to reliably redirect items on the line.
Thermoforming Clamping
Ideal for clamping fixtures in thermoforming machines, the 160 mm stroke provides ample travel for mould closure, while the 20 mm rod withstands the repetitive force cycles in a heated environment.
Is the Airtac SC50 Standard Cylinder SC50X160H the Right Cylinder?
Select the SC50X160H for applications requiring reliable actuation in elevated temperature environments up to 150 °C. If your force requirement is lower, consider stepping down to the 40 mm bore (879 N push at 0.7 MPa); for higher force, the 63 mm bore offers 2182 N at the same pressure. For a direct replacement, match the 50 mm bore, 160 mm stroke, PT port thread, and ensure the replacement cylinder also uses high-temperature seals. Note that for this 160 mm stroke, side loads should be avoided; use an external guide rail if the rod will experience lateral forces.
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 SC50X160H FAQ
At 0.7 MPa operating pressure, the SC50X160H double-acting cylinder produces a theoretical push force of 1374 N on the extension stroke and a pull force of 825 N on the retraction stroke.
Yes, the SC50X160H is dimensionally identical to the standard SC50X160 but is specifically designed for high-temperature operation. It is a direct fit if your application requires seals that withstand 0 to 150 °C instead of the standard -20 to +70 °C range.
