About the Airtac SC50 Standard Cylinder SC50X1370S
The SC50X1370S is a double-acting AirTAC SC tie-rod cylinder with a 50 mm bore and an extended 1370 mm stroke, built with a factory-installed magnet for direct mounting of CMSG/DMSG/EMSG sensors. This non-standard stroke exceeds the standard 1200 mm maximum for the 50 bore, making it a made-to-order unit for applications needing extra-long linear travel. At 0.7 MPa, it generates a push force of 1374 N, driven by a 20 mm diameter piston rod with M16x1.5 male threads.
With a body length A of 150 mm and a 21 mm adjustable air cushion at each end, the cylinder decelerates the piston smoothly to reduce end-of-stroke impact. The operating pressure range is 0.15-1.0 MPa on filtered air, and the standard TPU seals suit a temperature range of -20 to +70 °C. The PT1/4 port supplies both extend and retract strokes, and the built-in magnet allows easy position feedback without external brackets.

Where the Airtac SC50 Standard Cylinder SC50X1370S Is Used
Long-Reach Material Transfer
The 1370 mm stroke pushes or pulls parts across wide conveyor gaps or between distant process stations, with the magnetic piston confirming end-of-travel via barrel-mounted sensors.
Automated Gluing & Dispensing
Provides a steady, straight 1.37 m linear motion for adhesive or sealant dispensing heads, where mid-range force and sensor feedback ensure consistent bead placement.
Vertical Lift Assist
Used in a vertical orientation to raise or lower light payloads over a long distance, with the adjustable cushion softening the stop at both ends of the 1370 mm travel.
Is the Airtac SC50 Standard Cylinder SC50X1370S the Right Cylinder?
For a 50 mm bore, the SC50X1370S offers a mid-range force of 982 N push at 0.5 MPa. If your load requires more force, stepping up to the 63 mm bore provides 1559 N at the same pressure; for a lighter, more compact solution, the 40 mm bore delivers 628 N. At this 1370 mm stroke length, the unsupported rod is susceptible to bending under side loads—always use an external linear guide or a guided cylinder assembly to protect the rod bearing and seal from premature wear.
To replace an existing cylinder, match five points exactly: 50 mm bore, 1370 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic mounting configuration. This tie-rod design is shorter than an ISO 15552 cylinder and is not dimensionally interchangeable with that standard.

- ✓ 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 SC50X1370S FAQ
At the standard 0.7 MPa operating pressure, the cylinder produces 1374 N extending and 825 N retracting. The maximum theoretical force at 1.0 MPa is 200 kgf (1960 N) push.
No. At this stroke length, the 20 mm rod is vulnerable to bending and buckling under side loads or high acceleration. You must install an external guide rail or use a guided cylinder configuration to prevent rod damage and seal failure.
