About the Airtac SC50 Standard Cylinder SC50X335SH
The SC50X335SH 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 335 mm stroke, this model features a 20 mm diameter piston rod and M16x1.5 rod thread for robust connection, while the 21 mm adjustable air cushion at each end decelerates the piston to reduce end-of-stroke impact.
This variant is equipped with a built-in magnet (S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, enabling precise position feedback without external brackets. The H suffix specifies Viton (FKM) seals, extending the operating temperature range to 0–150 °C, making it suitable for hot environments where standard TPU seals would degrade. Ports are PT1/4.

Where the Airtac SC50 Standard Cylinder SC50X335SH Is Used
High-Temperature Actuation
Viton seals allow this cylinder to operate continuously in ambient temperatures up to 150°C, making it ideal for autoclave doors, drying ovens, and foundry equipment where standard seals would fail.
Sensor-Controlled Clamping
The built-in magnetic piston enables CMSG/DMSG sensors to detect end-of-stroke and mid-stroke positions, providing reliable confirmation for automated clamping, pressing, or ejection sequences.
Hot-Material Diverter Gates
With 1767 N of push force at 0.9 MPa and high-temperature resilience, this cylinder reliably actuates diverter gates and chutes handling hot aggregates, powders, or asphalt in processing plants.
Is the Airtac SC50 Standard Cylinder SC50X335SH the Right Cylinder?
For applications requiring slightly less force, the 40 mm bore SC40 series provides 628 N at 0.5 MPa, while stepping up to the 63 mm bore SC63 delivers 1559 N. At 335 mm stroke, the 20 mm rod is well-supported within the standard stroke range, but any side loading should be managed with an external guide or linear bearing to protect the rod bearing and seals from premature wear.
To guarantee a correct replacement, match five key attributes: 50 mm bore, 335 mm stroke, PT1/4 port thread, the built-in magnet for sensor compatibility, and the Viton seal material for high-temperature operation. This tie-rod cylinder is dimensionally shorter than an ISO 15552 profile cylinder and is not a direct interchange for that standard.
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 SC50X335SH FAQ
At the standard operating pressure of 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 at 1.0 MPa is 200 kgf.
No. As a standard double-acting cylinder, the SC50X335SH will drift or drop if air pressure is exhausted or the directional valve is centered. The adjustable air cushion only decelerates the piston at stroke end to soften impact; it is not a locking or holding device. For load holding without live pressure, add a pilot-operated check valve or an external rod brake.
