About the Airtac SC50 Standard Cylinder SC50X45H
The SC50X45H is a double-acting single-rod pneumatic cylinder with a 50 mm bore and 45 mm stroke, built for high-temperature duty. Its Viton (FKM) seals shift the operating range to 0–150 °C, making it suitable for autoclaves, drying lines, and hot-process automation where standard TPU seals would degrade.
At 0.5 MPa air pressure this cylinder pushes with 982 N and pulls with 825 N; at the maximum operating pressure of 0.9 MPa, thrust reaches 1767 N. The 20 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration in a compact tie-rod body just 150 mm long (A dimension).

Where the Airtac SC50 Standard Cylinder SC50X45H Is Used
Hot-Process Actuation
Viton seals allow the SC50X45H to cycle reliably in autoclave door locks, steam-valve operators, and foundry jigs where ambient temperatures reach 150 °C.
Medical Sterilisation Equipment
Withstands repeated steam-purge cycles in steriliser tray transfer and sealing stations. The 982 N push force at 0.5 MPa handles heavy lid clamps without elastomer swelling.
Hot-Melt Dispensing
Short 45 mm stroke and high-temperature resilience suit adhesive applicator heads and hot-glue press rams, delivering consistent 1767 N peak thrust at 0.9 MPa.
Is the Airtac SC50 Standard Cylinder SC50X45H the Right Cylinder?
Choose the SC50X45H when your stroke is short and the environment exceeds 70 °C—the Viton seal is mandatory for continuous hot operation. If you need more force at 0.5 MPa, step up to the SC63 bore (1559 N push); for a lighter, faster actuator, the SC40 delivers 628 N.
For replacement, match five points: 50 mm bore, 45 mm stroke, PT port thread (PT1/4), basic mount, and the -H high-temperature seal. This cylinder does not include a magnet; if sensor feedback is required, order the SC50X45SH variant with a built-in magnet for CMSG/DMSG sensors.
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 SC50X45H FAQ
At 0.7 MPa the 50 mm bore generates 1374 N pushing force and 1155 N pulling force (calculated from the 0.5 MPa pull ratio). The maximum operating thrust at 0.9 MPa is 1767 N push.
No—the SC50X45H does not have a built-in magnet (no -S suffix). To use CMSG/DMSG/EMSG sensors, order the SC50X45SH variant. If you only need end-of-stroke detection, external limit switches can be used with any SC cylinder.
