About the Airtac SC50 Standard Cylinder SC50X160SH
The SC50X160SH is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, configured with a 50 mm bore and 160 mm stroke. It delivers a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa, driven by a 20 mm diameter piston rod with an M16x1.5 male thread. The adjustable air cushion at each end (21 mm length) decelerates the piston smoothly, and the PT1/4 port supplies filtered air.
This model carries the 'H' suffix, indicating the seals are made from Viton (FKM) instead of the standard TPU. This shifts the operating temperature range to 0 to +150 °C, making the SC50X160SH suitable for high-temperature or chemically aggressive environments where standard seals would degrade. The body length is 150 mm, giving a total extended length of 310 mm, and the cylinder is supplied without a magnet or mounting accessories, ready for basic pin-eye or bracket mounting.

Where the Airtac SC50 Standard Cylinder SC50X160SH Is Used
High-Temperature Actuation
The Viton seals enable reliable operation in ovens, autoclaves, or near heat sources where ambient temperatures reach up to 150 °C, pushing or pulling components through thermal cycles.
Chemical Process Valves
With FKM's superior chemical resistance, this cylinder is ideal for actuating small ball or butterfly valves on lines carrying aggressive fluids, solvents, or hot cleaning agents.
Hot Mould Clamping
Delivers a consistent 982 N clamping force at 0.5 MPa for holding mould halves together in plastic injection or rubber vulcanization tools, resisting heat transfer from the tooling.
Is the Airtac SC50 Standard Cylinder SC50X160SH the Right Cylinder?
The SC50X160SH suits applications needing moderate force in a hot environment. For a step up in force at the same pressure, the 63 mm bore SC63 series provides 1559 N of push force at 0.5 MPa. If a lower force is sufficient and space is a constraint, the 40 mm bore SC40 series delivers 628 N. This 160 mm stroke is within the 1200 mm maximum standard stroke for the 50 mm bore.
To ensure a direct replacement, match five key points: the 50 mm bore, the 160 mm stroke, the PT1/4 port thread, the basic (no-bracket) mounting, and the absence of a built-in magnet. The Viton seals are critical for high-temperature compatibility; a standard TPU-sealed cylinder would fail prematurely in this application.
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 SC50X160SH 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 force at 1.0 MPa is 200 kgf.
Yes, the SC50X160SH is a direct dimensional and functional replacement for a standard SC50X160, but with Viton seals. It is essential for applications where the ambient or media temperature exceeds 70 °C, up to a maximum of 150 °C. The port, rod, and mounting dimensions are identical.
