About the Airtac SC50 Standard Cylinder SC50X150H
The SC50X150H is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, equipped with high-temperature Viton (FKM) seals that shift the operating range to 0–150 °C. With a 50 mm bore and 150 mm stroke, it produces a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa, making it suitable for hot-environment automation tasks.
This model features a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 port connections. The cylinder body length A is 150 mm, giving a total extended length of approximately 300 mm. Its adjustable air cushion (21 mm length) decelerates the piston near stroke end to reduce impact, but it does not lock the load—external holding is required if position must be maintained without pressure.

Where the Airtac SC50 Standard Cylinder SC50X150H Is Used
High-Temperature Process Automation
With Viton seals rated to 150°C, this cylinder reliably actuates gates, dampers, or clamps in ovens, autoclaves, and foundry equipment where standard seals would degrade.
Hot Press & Molding
Delivers 1767 N of force at 0.9 MPa for pressing, forming, or holding operations in heated platen presses and rubber molding machines, maintaining seal integrity under sustained heat.
Material Handling Near Heat Sources
Operates conveyors, diverters, or lift mechanisms positioned close to industrial dryers, kilns, or steam lines, where ambient temperatures exceed the standard 70°C limit of TPU seals.
Is the Airtac SC50 Standard Cylinder SC50X150H the Right Cylinder?
Choose the SC50X150H when your application demands a mid-range force actuator that withstands elevated temperatures. If you need more force, stepping up to the 63 mm bore provides 1559 N push at 0.5 MPa; for a lighter, more compact solution, the 40 mm bore delivers 628 N. The 150 mm stroke is well within the 1200 mm maximum standard stroke for this bore, ensuring standard availability.
For replacement, match five key points: 50 mm bore, 150 mm stroke, PT1/4 port thread, the basic (no-bracket) mounting configuration, and the absence of a built-in magnet. The Viton seal variant is critical for high-temperature compatibility—do not substitute a standard TPU-seal cylinder in hot environments.
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 SC50X150H FAQ
At 0.5 MPa (approximately 72 psi), the cylinder generates 982 N pushing force and 825 N pulling force. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The SC50X150H is a double-acting cylinder and does not lock or hold position when pressure is exhausted or the directional valve is centered. The piston will drift or drop under load. For load-holding applications, add an external rod brake, a pilot-operated check valve, or a mechanical lock.
