About the Airtac SC50 Standard Cylinder SC50X450SN
The SC50X450SN is a double-acting tie-rod cylinder delivering 1374 N of push force at 0.7 MPa, built for mid-range pneumatic applications requiring position sensing. With a 50 mm bore, 20 mm piston rod, and a 450 mm stroke, this model includes a built-in magnet (-S suffix) that allows CMSG/DMSG/EMSG reed or solid-state sensors to clamp directly onto the barrel for reliable end-of-stroke detection.
The cylinder body length A is 150 mm, giving a total extended length of approximately 600 mm. NBR seals (-N suffix) provide reliable sealing with standard compressed air, and the adjustable air cushion at each end decelerates the piston smoothly over a 21 mm cushion length. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa.

Where the Airtac SC50 Standard Cylinder SC50X450SN Is Used
Part Sorting & Diverting
The 450 mm stroke and sensor-ready design make this cylinder ideal for conveyor diverters and sorting gates, where mid-stroke or end-of-stroke position confirmation is required for sequencing.
Clamping & Fixturing
With 1374 N of clamping force at 0.7 MPa, this actuator suits CNC fixture clamping and assembly jigs. The built-in magnet enables sensor verification that the clamp is fully engaged before a cycle starts.
Pallet Stop & Lift
Used in material handling for pallet stops or short vertical lifts, the SC50X450SN provides consistent force and the NBR seals handle typical workshop air quality, while the sensor confirms the stop position.
Is the Airtac SC50 Standard Cylinder SC50X450SN the Right Cylinder?
The SC50 bore sits between the SC40 (879 N push at 0.7 MPa) and the SC63 (2182 N at 0.7 MPa). If your load requires more force, stepping up to a 63 mm bore nearly doubles the output; for lighter, faster-cycling loads, the 40 mm bore reduces air consumption. At a 450 mm stroke, the 20 mm rod is well-supported within standard limits, but any significant side load demands an external guide or a guided cylinder to prevent rod bearing wear and bending.
For a direct replacement, match these five points: 50 mm bore, 450 mm stroke, PT port thread, the built-in magnet for sensor compatibility, and the NBR seal material. This cylinder is not dimensionally interchangeable with ISO 15552 profile cylinders; it is a tie-rod design specific to the AirTAC SC family.
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 SC50X450SN FAQ
At the standard operating pressure of 0.7 MPa, this 50 mm bore cylinder produces 1374 N pushing force and 825 N pulling force. 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. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC50 cylinder with matching stroke, PT ports, NBR seals, and a built-in magnet.
