About the Airtac SC50 Standard Cylinder SC50X450H
The AirTAC SC50X450H is a double-acting tie-rod cylinder engineered for high-temperature environments, featuring Viton (FKM) seals that shift the operating range from the standard -20 to +70 °C up to 0 to +150 °C. With a 50 mm bore and 450 mm stroke, it generates a push force of 1374 N at 0.7 MPa and reaches a maximum theoretical thrust of 1767 N at 0.9 MPa, making it a strong mid-range actuator for hot-duty automation.
This model uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The adjustable pneumatic cushion at each end is 21 mm long, and the body length A is 150 mm. The total extended length is approximately 600 mm. It is a basic configuration without a magnet or mounting accessories, ready for direct integration or custom bracketing.

Where the Airtac SC50 Standard Cylinder SC50X450H Is Used
Foundry & Heat-Treat Actuation
Viton seals allow this cylinder to operate reliably in foundry shakeouts, oven door actuators, and autoclave loading systems where ambient temperatures reach 150 °C.
Hot-Melt Glue & Welding Fixtures
Provides consistent 1374 N clamping force at 0.7 MPa for hot-melt assembly stations and robotic welding jigs, resisting seal degradation from radiant heat.
Plastics Thermoforming Ejection
Delivers 450 mm of stroke for ejector plates and core pulls in thermoforming and injection molds, maintaining seal integrity during high-temperature cycling.
Is the Airtac SC50 Standard Cylinder SC50X450H the Right Cylinder?
Select the SC50X450H when your application requires a 50 mm bore cylinder that can withstand continuous ambient temperatures up to 150 °C. If your force requirement is lower, stepping down to a 40 mm bore reduces push force to 879 N at 0.7 MPa. For higher force needs, the 63 mm bore provides 2182 N at the same pressure.
For this 450 mm stroke, ensure the load is guided and side forces are eliminated. A long, unsupported 20 mm rod is susceptible to bending under lateral loads; use an external guide rail or rod-alignment coupler to protect the rod bearing and seals. When replacing an existing cylinder, match five points: 50 mm bore, 450 mm stroke, PT1/4 ports, the Viton seal material, and any external mounting accessories.
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 SC50X450H FAQ
At 0.7 MPa (7 bar) operating pressure, the 50 mm bore generates a theoretical push force of 1374 N. The pull force on the retract stroke is 825 N at the same pressure, accounting for the 20 mm rod area.
No. The SC50X450H is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is lost or the directional valve is centered, the piston will drift. For load holding, you must add an external pilot-operated check valve or a mechanical rod lock.
