About the Airtac SC50 Standard Cylinder SC50X130H
The SC50X130H is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, factory-equipped with high-temperature Viton (FKM) seals. With a 50 mm bore and 130 mm stroke, it delivers a push force of 982 N at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa, making it a robust mid-range actuator for hot environments.
This model uses a 20 mm diameter piston rod with an M16x1.5 rod thread and PT1/4 ports. The adjustable air cushion at each end is 21 mm long, and the body length A is 150 mm. The Viton seal package shifts the operating temperature range to 0 to +150 °C, suitable for applications near ovens, autoclaves, or other heat sources where standard seals would degrade.

Where the Airtac SC50 Standard Cylinder SC50X130H Is Used
High-Temperature Material Handling
Viton seals allow the SC50X130H to operate reliably at up to 150 °C, making it ideal for actuating gates, clamps, or pushers inside industrial ovens, kilns, and autoclave loading systems.
Hot Press & Molding Clamping
With 1767 N of force at 0.9 MPa, this cylinder provides consistent clamping pressure for heated platen presses in rubber molding, composite curing, and plastic welding machinery.
Sterilization Equipment Actuation
The 0–150 °C temperature range suits steam sterilization and clean-in-place (CIP) environments, where the cylinder can actuate doors, valves, or lifts without seal failure from process heat.
Is the Airtac SC50 Standard Cylinder SC50X130H the Right Cylinder?
Choose the SC50 bore when your application needs between 825 N (pull at 0.5 MPa) and 1767 N (push at 0.9 MPa). If you require more force, step up to the SC63 which provides 1559 N of push at 0.5 MPa; for a lighter, more compact solution, the SC40 delivers 628 N at 0.5 MPa. The 130 mm stroke is a standard length for this bore.
For a direct replacement, match five points: 50 mm bore, 130 mm stroke, PT port thread, basic mounting (no bracket), and no magnet. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders. The Viton seal option is critical if the operating temperature exceeds 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 SC50X130H FAQ
At 0.5 MPa supply pressure, 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 increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The SC50X130H is a double-acting cylinder and does not lock or hold position when air pressure is exhausted or the directional valve is centered. The piston will drift or drop under load. If load holding is required, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
