About the Airtac SC50 Standard Cylinder SC50X1440S
The AirTAC SC50X1440S is a double-acting single-rod pneumatic cylinder with a 50 mm bore and an extended 1440 mm stroke, built for long linear movements in custom machinery. This model includes a built-in magnet, allowing direct mounting of CMSG/DMSG/EMSG sensors along the tie-rod barrel for precise position feedback without external brackets.
With a 20 mm diameter piston rod and PT1/4 ports, it generates 982 N of push force at 0.5 MPa and reaches 1767 N at the maximum operating pressure of 0.9 MPa. The 21 mm adjustable air cushion at each end decelerates the piston smoothly, protecting end caps during high-speed operation. Because the 1440 mm stroke exceeds the standard 1200 mm maximum for bore 50, this is a non-standard, made-to-order configuration.

Where the Airtac SC50 Standard Cylinder SC50X1440S Is Used
Long-Reach Material Transfer
The 1440 mm stroke pushes or pulls parts across wide conveyor gaps or between distant stations, with the magnet confirming full extension and retraction.
Automated Welding Fixtures
Positions clamping arms over a large work area. The 1767 N force at 0.9 MPa secures heavy weldments, while sensor feedback ensures the clamp is fully engaged.
Custom Packaging Pushers
Ejects large boxes or pallets from a packing line. The adjustable cushioning prevents impact damage to the load at the end of the long stroke.
Is the Airtac SC50 Standard Cylinder SC50X1440S the Right Cylinder?
For applications needing more force, stepping up to a 63 mm bore provides 1559 N at 0.5 MPa, a significant increase. If a shorter standard stroke is acceptable, the SC50X1000 is available from stock. At 1440 mm, the rod is highly extended; side loads must be avoided to prevent rod bending and premature bearing wear. Use an external linear guide or a guided cylinder for any off-axis force.
When replacing this cylinder, match five key points: 50 mm bore, 1440 mm stroke, PT port thread, the built-in magnet (-S suffix), and the basic mounting style. This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with those types.
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 SC50X1440S FAQ
At 0.5 MPa, the theoretical push force is 982 N. At 0.7 MPa, it rises to 1374 N, and at the maximum operating pressure of 0.9 MPa, it delivers 1767 N. For precise sizing under your specific friction and load conditions, confirm from the datasheet.
Only if the load is purely axial and perfectly aligned with the rod. A 1440 mm stroke with a 20 mm rod is highly susceptible to bending under side load. For any off-axis force, an external linear guide rail or rod support is essential to prevent premature seal and bearing failure.
