About the Airtac SC50 Standard Cylinder SC50X1350S
This AirTAC SC50X1350S is a double-acting single-rod tie-rod cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at 0.9 MPa. With a 50 mm bore and an extended 1350 mm stroke, it is built for long linear movements where standard 1200 mm strokes fall short. The 20 mm diameter rod and 21 mm adjustable air cushion ensure smooth end-of-stroke deceleration.
A built-in magnet is integrated into the piston, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly on the barrel for reliable, non-contact position sensing. The body length A is 150 mm, and the total extended length reaches approximately 1500 mm. Operating on filtered air from 0.15 to 1.0 MPa, this cylinder uses PT ports and standard TPU seals for a temperature range of -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X1350S Is Used
Long-Stroke Material Pusher
The 1350 mm stroke and 982 N force at 0.5 MPa efficiently push heavy bins or pallets across wide roller conveyors, with the built-in magnet confirming full extension and retraction.
High-Bay Diverter Gate
Controls a tall diverter chute in a warehouse sortation system. The long stroke moves a large gate panel, and the magnetic piston provides end-of-travel feedback to the PLC.
Automated Glue Bead Applicator
Traverses a glue head along a 1350 mm path on large panels. The smooth, adjustable air cushion prevents vibration at stroke ends, ensuring a consistent, high-quality adhesive bead.
Is the Airtac SC50 Standard Cylinder SC50X1350S the Right Cylinder?
For applications needing a 50 mm bore, the SC50X1350S provides a mid-range force class; stepping down to a 40 mm bore reduces push force to 628 N at 0.5 MPa, while stepping up to a 63 mm bore increases it to 1559 N. Because this cylinder has a long 1350 mm stroke, the unsupported rod is susceptible to bending under side loads—always use an external guide rail or a guided cylinder to protect the rod bearing and seals. When replacing, match exactly: 50 mm bore, 1350 mm stroke, PT port thread, built-in magnet (-S), and basic mounting. This stroke exceeds the standard maximum of 1200 mm for a 50 mm bore, making it a non-standard, made-to-order item.
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 SC50X1350S FAQ
The theoretical push force is 982 N at 0.5 MPa, 1374 N at 0.7 MPa, and 1767 N at the maximum operating pressure of 0.9 MPa. The pull force on the retract stroke is 825 N at 0.5 MPa due to the rod area.
No, the 1350 mm stroke is a non-standard, made-to-order length that exceeds the 1200 mm maximum standard stroke for a 50 mm bore. For such a long stroke, an external guide rail or a self-guided cylinder is strongly recommended to prevent the 20 mm rod from bending under side load, which can damage the rod bearing and seals.
