About the Airtac SC50 Standard Cylinder SC50X1345S
The AirTAC SC50X1345S is a double-acting single-rod pneumatic cylinder with a 50 mm bore and an extended 1345 mm non-standard stroke, built for applications demanding a long linear reach. This model includes a built-in magnet (-S suffix), allowing CMSG/DMSG/EMSG reed or solid-state sensors to be clamped directly onto the tie-rod barrel for precise, contactless end-of-stroke detection.
At the standard 0.9 MPa operating pressure, it generates a theoretical push force of 1767 N, driven by a 20 mm diameter piston rod with an M16x1.5 male thread. The cylinder body length is 150 mm, making the total extended length approximately 1495 mm. It features an adjustable pneumatic cushion (21 mm length) at both ends to decelerate the piston smoothly, and uses PT1/4 port threads with TPU seals for a standard operating temperature range of -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X1345S Is Used
Long-Reach Material Transfer
Pushes or pulls parts across wide conveyor gaps or between distant stations, using the 1345 mm stroke to bridge large spans without a complex multi-stage actuator.
Automated Tool Actuation
Extends a clamping or stamping tool deep into a fixture on custom machinery, with the built-in magnet providing sensor feedback to the PLC for cycle confirmation.
Diverting Gates on Long Chutes
Operates a high-reach diverter gate in packaging or logistics lines, where the long stroke is needed to fully open or close a tall material flow path.
Is the Airtac SC50 Standard Cylinder SC50X1345S the Right Cylinder?
This 50 mm bore cylinder provides 982 N of push force at 0.5 MPa. If your application requires more force, stepping up to a 63 mm bore offers 1559 N at the same pressure; for a lighter, more compact solution, the 40 mm bore delivers 628 N. This model is a genuine AirTAC SC tie-rod cylinder, dimensionally shorter than an ISO 15552 profile, and is a direct replacement only for another SC50 cylinder matching this bore, stroke, PT port, basic mount, and built-in magnet.
With a stroke of 1345 mm, the 20 mm rod is highly susceptible to bending under side loads. Never use this cylinder to guide or support a lateral load directly. For long-stroke applications, always couple the rod to an external linear guide rail or switch to a guided cylinder unit to protect the rod bearings and ensure reliable operation.
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 SC50X1345S FAQ
The theoretical force depends on your air pressure. At 0.5 MPa it produces 982 N, at 0.7 MPa it produces 1374 N, and at the maximum operating pressure of 0.9 MPa it reaches 1767 N. The pull force on the retract stroke is lower due to the rod area; at 0.5 MPa it is 825 N.
Yes. The 'S' in the model code SC50X1345S means it has a built-in magnet on the piston. You can directly clamp compatible AirTAC CMSG, DMSG, or EMSG sensors onto the cylinder's tie-rod barrel to detect piston position, with no need for external brackets or flags.
