About the Airtac SC50 Standard Cylinder SC50X42H
The SC50X42H is a double-acting pneumatic cylinder with a 50 mm bore and 42 mm stroke, fitted with high-temperature Viton (FKM) seals that shift the operating range to 0–150 °C. 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 compact workhorse for hot-environment actuation.
This tie-rod cylinder uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The adjustable air cushion (21 mm length) decelerates the piston quietly, and the body length A is 150 mm. The -H suffix specifies genuine Viton seals for reliable performance in aggressive or elevated-temperature applications.

Where the Airtac SC50 Standard Cylinder SC50X42H Is Used
Hot Press & Molding
Viton seals allow the SC50X42H to operate reliably in hydraulic press clamping and thermoforming tools where ambient temperatures reach up to 150 °C, providing consistent 1767 N clamping force.
Autoclave & Sterilization
Suited for autoclave door actuation or medical device assembly in high-temperature sterilization zones, thanks to the FKM seal material that resists steam and aggressive cleaning agents.
Soldering & Welding Fixtures
Withstands the radiated heat from nearby soldering or welding processes, using its 20 mm rod and 42 mm stroke to position small components or actuate clamps without seal degradation.
Is the Airtac SC50 Standard Cylinder SC50X42H the Right Cylinder?
Choose the SC50 bore when your application needs roughly 1000 N of push force at standard plant pressure. If you require more force, step up to the SC63 (1559 N at 0.5 MPa); for a lighter, more compact solution, the SC40 delivers 628 N. The 42 mm stroke is a standard length within the 50 mm bore’s maximum of 1200 mm.
For a direct replacement, match these five points: 50 mm bore, 42 mm stroke, PT1/4 port thread, basic (no mounting accessory), and no magnet. This model uses Viton seals—ensure the replacement also specifies high-temperature seals if the ambient 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 SC50X42H FAQ
At 0.7 MPa supply pressure, the SC50X42H generates a theoretical push force of 1374 N and a pull force of 825 N. The maximum operating push force at 0.9 MPa is 1767 N.
Yes, the dimensions, port thread (PT1/4), and rod thread (M16x1.5) are identical. The only difference is the Viton seal material, which extends the operating temperature range from -20–70 °C (standard TPU) to 0–150 °C, making it suitable for high-temperature environments.
