About the Airtac SC50 Standard Cylinder SC50X10H
The SC50X10H is a compact-stroke double-acting pneumatic cylinder built for high-temperature environments. Its Viton (FKM) seals shift the operating range to 0–150 °C, making it suitable for autoclaves, drying lines, and foundry equipment where standard seals would degrade. At 0.5 MPa, this 50 mm bore unit generates 982 N of push force and 825 N on the pull stroke.
With a 10 mm stroke, the cylinder provides a short, precise linear motion ideal for clamping, ejecting, or positioning in hot zones. The tie-rod construction keeps the overall length compact—the body length A is just 150 mm, yielding a total extended length of approximately 160 mm. The 20 mm diameter piston rod and M16x1.5 male rod thread handle direct axial loads reliably. Adjustable air cushioning at both ends decelerates the piston over a 21 mm cushion length, reducing end-of-stroke impact even in rapid cycling.

Where the Airtac SC50 Standard Cylinder SC50X10H Is Used
Hot-Zone Clamping
Viton seals withstand 0–150 °C ambient, making the SC50X10H ideal for short-stroke clamping fixtures inside ovens, autoclaves, or heated press tools where standard seals would fail.
High-Temp Part Ejection
The 10 mm stroke provides a quick, repeatable push to eject small hot parts from molds or forming dies. The 20 mm rod resists buckling under the 982 N push force at 0.5 MPa.
Sterilizer Actuation
With FKM seals rated for repeated steam or dry-heat sterilization cycles, this cylinder suits short-throw valve or gate actuation inside medical and food-processing sterilizers.
Is the Airtac SC50 Standard Cylinder SC50X10H the Right Cylinder?
For applications needing more force at the same 10 mm stroke, stepping up to the 63 mm bore SC63 series provides 1559 N of push force at 0.5 MPa. If a lower force and smaller footprint are preferred, the 40 mm bore SC40 series delivers 628 N at 0.5 MPa. This model uses PT (tapered) ports; ensure your fittings match. The -H suffix specifies Viton seals for high-temperature operation—do not substitute with a standard TPU seal cylinder if the ambient temperature exceeds 70 °C. When replacing an existing cylinder, match five points: 50 mm bore, 10 mm stroke, PT port thread, basic (no bracket) mounting, and the high-temperature seal material.
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 SC50X10H FAQ
At 0.7 MPa operating pressure, the 50 mm bore SC cylinder produces 1374 N of push force on the piston and 825 N of pull force on the rod side. The maximum operating force at 0.9 MPa is 1767 N push.
Yes. The SC50X10H is the direct high-temperature replacement. The -H suffix indicates Viton (FKM) seals rated for 0 to +150 °C, whereas the standard TPU seal is limited to -20 to +70 °C. All other dimensions—50 mm bore, 10 mm stroke, PT ports, and tie-rod body—remain identical.
