About the Airtac SC50 Standard Cylinder SC50X1400S
The SC50X1400S is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa, scaling to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and a 20 mm diameter piston rod, this model is specified for a 1400 mm stroke, which exceeds the standard maximum of 1200 mm, making it a non-standard, made-to-order configuration.
This tie-rod cylinder features an adjustable pneumatic cushion (21 mm length) to decelerate the piston smoothly at end-of-stroke. The integrated magnet (suffix -S) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for reliable, non-contact position sensing. It uses a PT1/4 port and operates on filtered air from 0.15 to 1.0 MPa.

Where the Airtac SC50 Standard Cylinder SC50X1400S Is Used
Long-Stroke Material Transfer
The 1400 mm stroke moves parts between distant conveyor lines or workstations. The built-in magnet enables end-of-stroke confirmation via barrel-mounted sensors.
Automated Gluing or Dispensing
Provides a steady, linear 982 N push at 0.5 MPa for applying adhesives or sealants along a long bead. Sensor feedback ensures the carriage returns fully before the next cycle.
Vertical Pallet Lifting
With 825 N of pull force at 0.5 MPa, it can raise and lower light pallet layers in a compact lifting frame. An external guide is essential to prevent rod buckling under vertical side loads.
Is the Airtac SC50 Standard Cylinder SC50X1400S the Right Cylinder?
Select the SC50 when your application requires a force class between the smaller SC40 (628 N push at 0.5 MPa) and the larger SC63 (1559 N push at 0.5 MPa). For this 1400 mm stroke, side-load management is critical; an unsupported 20 mm rod at full extension is vulnerable to bending under lateral forces. Always use an external guide or a guided cylinder assembly for off-axis loads.
For a direct replacement, match five key specifications: 50 mm bore, 1400 mm stroke, PT1/4 port thread, the built-in magnet for sensor compatibility, and the basic (no bracket) mounting configuration. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC50X1400S FAQ
At 0.5 MPa, it generates 982 N extending and 825 N retracting. At the maximum operating pressure of 0.9 MPa, the extending force increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. For any stroke of 300 mm or more, and especially at 1400 mm, the 20 mm diameter rod is susceptible to bending and bearing damage if subjected to even minor side loads. An external guide rail or a guided cylinder configuration is required to absorb lateral forces and protect the rod.
