About the Airtac SC50 Standard Cylinder SC50X150SH
The SC50X150SH is a double-acting pneumatic cylinder with a 50 mm bore and 150 mm stroke, delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and Viton (FKM) seals (-H suffix) that shift the operating temperature range to 0 to +150 °C, making it suitable for hot environments.
With a 20 mm diameter piston rod and an M16x1.5 rod thread, the cylinder provides a 21 mm adjustable air cushion at each end to decelerate the piston smoothly. The body length A is 150 mm, giving a total extended length of approximately 300 mm. Ports are PT1/4, and the maximum standard stroke for this bore is 1200 mm.

Where the Airtac SC50 Standard Cylinder SC50X150SH Is Used
High-Temperature Actuation
With Viton seals rated for 0 to +150 °C, this cylinder is ideal for pressing, clamping, or ejecting parts near ovens, autoclaves, or heated platens where standard seals would degrade.
Sensor-Controlled Sorting Gates
The built-in magnet allows CMSG/DMSG sensors to clamp directly onto the barrel for precise end-of-stroke detection, perfect for diverting packages on a conveyor line.
Hot-Melt Glue Dispensing
Reliably advances a dispensing head in a hot-melt assembly station. The 982 N force at 0.5 MPa provides ample power for consistent adhesive application.
Is the Airtac SC50 Standard Cylinder SC50X150SH the Right Cylinder?
Choose the SC50 bore for applications needing around 982 N of force at standard plant pressure. If your load requires more force, step up to the SC63 bore, which provides 1559 N at 0.5 MPa. For a lighter, more compact solution, the SC40 bore delivers 628 N. The 150 mm stroke is a standard length, ensuring quick availability.
When replacing an existing cylinder, match these five points exactly: 50 mm bore, 150 mm stroke, PT1/4 port thread, the built-in magnet for sensors, and the Viton seal material for high-temperature compatibility. This is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profiles.
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 SC50X150SH 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 increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The SC50X150SH is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The piston can drift or drop. For load holding without pressure, you must add an external rod brake or a pilot-operated check valve.
