About the Airtac SC50 Standard Cylinder SC50X105H
The SC50X105H is a double-acting tie-rod cylinder with a 50 mm bore and 105 mm stroke, fitted with high-temperature Viton (FKM) seals that shift the operating range to 0–150 °C. At 0.5 MPa it delivers 982 N pushing force and 825 N pulling force, making it suitable for medium-duty automation in hot environments.
The 20 mm diameter piston rod runs through a 21 mm adjustable air cushion at each end, helping to decelerate the load smoothly. Its PT1/4 port threads and M16x1.5 rod thread are standard for the 50 mm bore, and the body length A is 150 mm.

Where the Airtac SC50 Standard Cylinder SC50X105H Is Used
Hot-Zone Material Handling
Viton seals allow the SC50X105H to operate continuously at 150°C, making it ideal for actuators near ovens, autoclaves, or engine test cells where standard seals would degrade.
Clamping & Holding in Foundries
With 982 N of push force at 0.5 MPa and a 105 mm stroke, this cylinder provides consistent clamping pressure for moulds and fixtures in high-ambient-temperature foundry environments.
Sterilisation & Autoclave Actuation
The FKM seals withstand repeated steam sterilisation cycles. Use this 50 mm bore cylinder for door locks, valve actuation, or tray handling inside autoclave chambers.
Is the Airtac SC50 Standard Cylinder SC50X105H the Right Cylinder?
Choose the SC50X105H when your application needs a 105 mm stroke in a 50 mm bore with reliable high-temperature sealing. If you need more force, step up to the 63 mm bore (1559 N push at 0.5 MPa); for a lighter, more compact solution the 40 mm bore delivers 628 N. The 105 mm stroke is well within the 1200 mm maximum standard stroke for this bore.
When replacing an existing cylinder, match five points: 50 mm bore, 105 mm stroke, PT port thread, Viton seal material, and basic (no accessory) mounting. This cylinder does not include a magnet; if you need sensor feedback, order the -S magnet variant.
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 SC50X105H FAQ
At 0.5 MPa (approximately 5 bar), the SC50X105H produces 982 N pushing force and 825 N pulling force. At the maximum operating pressure of 0.9 MPa, pushing force increases to 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The SC series is a tie-rod cylinder and is shorter than an ISO 15552 cylinder, so dimensions and mounting interfaces are not interchangeable. Only replace another AirTAC SC tie-rod cylinder with matching bore, stroke, port thread, seal material, and mounting type.
