About the Airtac SC50 Standard Cylinder SC50X305S
The SC50X305S is a double-acting pneumatic cylinder with a 50 mm bore and a non-standard 305 mm stroke, built on the compact AirTAC SC tie-rod platform. At 0.5 MPa it generates 982 N of push force and 825 N of pull force, rising to 1767 N push at 0.9 MPa. The 20 mm diameter piston rod and PT1/4 ports suit general automation tasks requiring a mid-range force output.
This model includes the -S suffix, equipping the cylinder with a built-in magnet. This allows CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly onto the barrel for precise, non-contact end-of-stroke or mid-stroke position sensing. The standard TPU seals provide a reliable operating temperature range of -20 to +70 °C, and the adjustable air cushion at each end decelerates the piston smoothly within its 21 mm cushion length.

Where the Airtac SC50 Standard Cylinder SC50X305S Is Used
Part Sorting Gate
Actuates a diverter gate on a conveyor line. The 982 N push force at 0.5 MPa reliably shifts packages, while the integrated magnet signals gate position to the PLC via a DMSG sensor.
Clamping & Staking Fixture
Provides a controlled 1767 N clamping force at 0.9 MPa for a welding staking fixture. The 305 mm stroke offers ample retraction clearance for loading large parts.
Pallet Stop & Lift
Powers a lift-and-stop mechanism at the end of a gravity roller lane. The built-in magnet confirms the raised position, preventing the next pallet from advancing until the lane is clear.
Is the Airtac SC50 Standard Cylinder SC50X305S the Right Cylinder?
Select the SC50 when your application needs a force step up from the 32 mm bore (402 N push at 0.5 MPa) without moving to the larger 63 mm frame. For this 305 mm stroke, which exceeds the standard maximum of 1200 mm for a 50 mm bore, it is a made-to-order item. Ensure the 20 mm rod is adequately supported against side loads; at this extended length, an external guide or a guided cylinder should be used to prevent rod bending and premature bearing wear.
For a direct replacement, match five key points: 50 mm bore, 305 mm stroke, PT1/4 port thread, the built-in magnet for sensor compatibility, and the basic (no bracket) mounting configuration. This cylinder is not dimensionally interchangeable with ISO 15552 profiles; it is a tie-rod design that is shorter in overall length.
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 SC50X305S FAQ
At the standard operating pressure of 0.5 MPa, the cylinder provides 982 N of push force and 825 N of pull force. 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.
Yes. The -S suffix in the model code SC50X305S indicates a built-in magnet on the piston. This allows you to clamp compatible AirTAC CMSG, DMSG, or EMSG sensors directly onto the barrel's tie-rod slots to detect end-of-stroke or intermediate positions without physical contact.
