About the Airtac SC50 Standard Cylinder SC50X50SH
The AirTAC SC50X50SH is a double-acting tie-rod cylinder with a 50 mm bore and 50 mm stroke, factory-equipped with a built-in magnet (-S) and high-temperature Viton seals (-H). With a push force of 982 N at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa, it handles short-stroke clamping and ejector tasks in hot environments.
Its 20 mm diameter piston rod and M16x1.5 rod thread provide robust linear guidance for the 50 mm travel. The adjustable air cushion (21 mm length) decelerates the end-of-stroke mass smoothly, and the PT1/4 port supplies ample flow. Because the Viton seals shift the operating temperature range to 0–150 °C, this cylinder is suited for autoclaves, drying ovens, and foundry equipment where standard seals would degrade.

Where the Airtac SC50 Standard Cylinder SC50X50SH Is Used
Hot Press & Autoclave Actuation
Viton seals withstand 0–150 °C, making the SC50X50SH ideal for short-stroke clamping in heated platen presses, autoclave door locks, and steam-assisted moulding tools.
High-Temp Part Ejection
The 50 mm stroke and 982 N push force reliably eject hot formed parts from dies or ovens. The built-in magnet enables end-of-stroke confirmation with a CMSG sensor even through thermal shielding.
Sterilisation & Lab Equipment
Operates reliably in clean-in-place and sterilisation cycles up to 150 °C. Use the SC50X50SH for actuator arms in laboratory autoclaves or pharmaceutical drying chambers.
Is the Airtac SC50 Standard Cylinder SC50X50SH the Right Cylinder?
Choose the SC50X50SH for hot-zone applications requiring position sensing via the built-in magnet—mount CMSG/DMSG/EMSG sensors directly on the barrel. If your force requirement is lower at 0.5 MPa, the 40 mm bore (628 N push) may be sufficient; for higher force, step up to the 63 mm bore (1559 N push).
When replacing an existing cylinder, match all five points: 50 mm bore, 50 mm stroke, PT1/4 port thread, the -S magnet for sensor compatibility, and the -H Viton seal material for high-temperature operation. The SC is a tie-rod design, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC50 cylinder.
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 SC50X50SH FAQ
At 0.7 MPa supply pressure, the 50 mm bore double-acting cylinder produces a theoretical push force of 1374 N and a pull force of 825 N. The maximum operating force at 0.9 MPa is 1767 N push.
Yes, provided the original is an AirTAC SC50 tie-rod cylinder. The -H suffix upgrades the seals to Viton (FKM), shifting the operating temperature from -20–70 °C to 0–150 °C. The -S magnet adds sensor capability. Ensure the PT1/4 port and M16x1.5 rod thread match your existing setup.
