About the Airtac SC50 Standard Cylinder SC50X140SH
The SC50X140SH is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and 140 mm stroke, this model features a 20 mm diameter piston rod and PT1/4 ports, making it a robust mid-range actuator for industrial automation tasks.
This variant includes a built-in magnet (-S) for direct mounting of CMSG, DMSG, or EMSG sensors, and is equipped with high-temperature Viton (FKM) seals (-H). The Viton material shifts the operating temperature range to 0 to +150 °C, making it suitable for hot environments where standard seals would degrade. The body length A is 150 mm, giving a total extended length of 290 mm.

Where the Airtac SC50 Standard Cylinder SC50X140SH Is Used
High-Temperature Clamping
With Viton seals rated to 150 °C, this cylinder is ideal for clamping fixtures in autoclaves, heated presses, or near foundry equipment where ambient heat would damage standard NBR or TPU seals.
Sensor-Equipped Actuation
The built-in magnet allows CMSG/DMSG sensors to clamp directly onto the tie-rod barrel. Perfect for pick-and-place units or diverters where end-of-stroke confirmation is required by the machine controller.
Product Stopper Gate
Generating 982 N at 0.5 MPa, the SC50X140SH provides ample force to stop and hold medium-weight packages on a conveyor line, with the sensor confirming the gate is fully retracted.
Is the Airtac SC50 Standard Cylinder SC50X140SH the Right Cylinder?
Select the SC50 when your application requires a force between the 628 N of the SC40 and the 1559 N of the SC63 at 0.5 MPa. The 140 mm stroke is well within the 1200 mm maximum standard stroke for this bore, ensuring standard availability. For a drop-in replacement, match the 50 mm bore, 140 mm stroke, PT1/4 port thread, and ensure the replacement also has the -S magnet and -H Viton seal options.
For strokes of 300 mm or more on a 20 mm rod, consider an external guide or a guided cylinder to prevent rod bearing damage from side loads. This 140 mm stroke is generally short enough for direct mounting, but always align the load with the rod axis to maximize seal life.
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 SC50X140SH FAQ
At 0.7 MPa, the theoretical push force is 1374 N. The pull force on the retract stroke is 825 N at 0.5 MPa, due to the reduced piston area on the rod side.
No. The SC series is a tie-rod cylinder and is dimensionally shorter than an ISO 15552 profile cylinder. It is not interchangeable with ISO 15552 mounts. Use AirTAC SC-specific mounting accessories like the FA, FB, CA, CB, or LB brackets.
