About the Airtac SC50 Standard Cylinder SC50X40SH
The SC50X40SH is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa, ideal for short-stroke clamping and ejecting tasks. Its 20 mm rod and 21 mm adjustable air cushion provide smooth deceleration in a compact 190 mm extended length.
This model features a built-in magnet (-S) for direct mounting of CMSG/DMSG sensors, and Viton (FKM) seals (-H) rated for 0 to +150°C, making it suitable for high-temperature environments. It uses standard PT ports and a tie-rod construction that is shorter than an ISO 15552 profile.

Where the Airtac SC50 Standard Cylinder SC50X40SH Is Used
Hot Press Actuation
Viton seals allow reliable operation in 0-150°C environments like heated platen presses, laminators, or drying ovens where standard seals would degrade.
Sensor-Controlled Clamping
The integrated magnet enables CMSG/DMSG sensors to confirm clamp position, providing closed-loop feedback for automated CNC fixtures and assembly jigs.
High-Temp Part Ejection
With 982 N of push force at 0.5 MPa, this cylinder ejects hot molded parts or stamped metal from dies, withstanding the radiant heat from the tooling.
Is the Airtac SC50 Standard Cylinder SC50X40SH the Right Cylinder?
For applications needing more force, the SC63 series offers 1559 N at 0.5 MPa. This SC50X40SH is a short-stroke unit; ensure side loads are minimal as the rod bearing is not designed for high radial forces. Always match replacement cylinders on bore, stroke, port thread (PT), magnet option (-S), and seal material (Viton).
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 SC50X40SH FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N. These values are based on the 50 mm bore and 20 mm rod diameter.
No. The SC50X40SH is a double-acting cylinder and will not hold position if air pressure is lost or the valve is centered. The adjustable air cushion only decelerates the piston at end-of-stroke. For load holding without live pressure, you must add a pilot-operated check valve or external rod brake.
