About the Airtac SC50 Standard Cylinder SC50X30H
The AirTAC SC50X30H is a double-acting single-rod pneumatic cylinder with a 50 mm bore and a short 30 mm stroke. It delivers 982 N of push force at 0.5 MPa and up to 1767 N at 0.9 MPa, driven by a 20 mm diameter piston rod with M16x1.5 male threads.
This model is fitted with Viton (FKM) seals, shifting the operating temperature range to 0 to +150 °C for hot or chemically aggressive environments. The compact tie-rod body has a length A of 150 mm, and the adjustable air cushion (21 mm) decelerates the piston at end-of-stroke to reduce impact noise.

Where the Airtac SC50 Standard Cylinder SC50X30H Is Used
Hot Press & Autoclave Actuation
The Viton seals handle ambient temperatures up to 150°C, making the SC50X30H suitable for short-stroke clamping or ejection in heated platen presses, autoclaves, and drying ovens.
High-Temperature Valve Control
With 982 N of force at 0.5 MPa, this 30 mm stroke cylinder reliably actuates small steam or hot-fluid valves in process industries where NBR or TPU seals would degrade.
Hot-Stamping & Marking
The compact 150 mm body length and short 30 mm stroke fit tight spaces on hot-foil stamping or branding machines, delivering consistent force at elevated temperatures.
Is the Airtac SC50 Standard Cylinder SC50X30H the Right Cylinder?
The SC50 bore provides 982 N at 0.5 MPa, sitting between the SC40 (628 N) and SC63 (1559 N). Step up to the 63 mm bore if your load exceeds 80% of this force at your working pressure. For this 30 mm stroke, side loading is minimal, but always align the rod with the load axis to prevent premature bearing wear.
When replacing an existing cylinder, match five points: 50 mm bore, 30 mm stroke, PT1/4 port thread, basic mounting (no bracket), and the -H Viton seal option. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC50X30H FAQ
At 0.5 MPa operating pressure, the SC50 bore produces 982 N pushing force and 825 N pulling force. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The SC50X30H 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 under external load. For load holding without live pressure, add a pilot-operated check valve or an external rod brake.
