About the Airtac SC50 Standard Cylinder SC50X425SH
The SC50X425SH is a double-acting pneumatic cylinder delivering 1374 N of push force at 0.7 MPa, making it a robust mid-range actuator for industrial automation. Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for the 425 mm stroke, while the built-in magnet enables direct mounting of CMSG/DMSG/EMSG sensors for precise end-of-stroke detection.
Equipped with Viton (FKM) seals, this model operates reliably in high-temperature environments from 0 to +150°C, extending service life in demanding applications like foundries or drying ovens. The tie-rod construction keeps the body length compact at 150 mm (A dimension), with a total extended length of approximately 575 mm.

Where the Airtac SC50 Standard Cylinder SC50X425SH Is Used
High-Temperature Process Automation
Viton seals allow the SC50X425SH to operate continuously at up to 150°C, making it ideal for actuating dampers, gates, or clamps in autoclaves, drying lines, and heat-treatment equipment.
Material Handling & Sorting
With 1374 N of push force at 0.7 MPa, this cylinder efficiently diverts or stops packages on conveyor lines. The built-in magnet provides sensor feedback for precise sortation timing.
Press & Clamping Fixtures
The 425 mm stroke and 1767 N maximum thrust at 0.9 MPa suit medium-duty pressing, holding, or riveting operations where sensor confirmation of rod position is required for safety interlocks.
Is the Airtac SC50 Standard Cylinder SC50X425SH the Right Cylinder?
For applications requiring more force, stepping up to the 63 mm bore SC63 series provides 2182 N at 0.7 MPa, while the 40 mm bore offers a lighter 879 N. At a 425 mm stroke, ensure the rod is not subjected to significant side loads; if lateral forces are present, pair the cylinder with an external linear guide or consider a guided cylinder to prevent rod bending and premature seal wear.
To guarantee a correct replacement, match five key specifications: 50 mm bore, 425 mm stroke, PT port thread, the built-in magnet (-S suffix), and the Viton seal material (H suffix). This model uses the standard basic mounting configuration with no additional brackets.
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 SC50X425SH FAQ
At 0.5 MPa, the cylinder produces 982 N pushing and 825 N pulling. At the maximum operating pressure of 0.9 MPa, the pushing force increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
Yes, provided the existing unit is a 50 mm bore, 425 mm stroke tie-rod cylinder with PT ports, a built-in magnet, and Viton seals. The SC series is not dimensionally interchangeable with ISO 15552 profile cylinders, so verify the body length (A=150 mm) and mounting hole pattern match your current setup.
