About the Airtac SC50 Standard Cylinder SC50X1400
The AirTAC SC50X1400 is a double-acting tie-rod cylinder engineered for long linear movements requiring a 1400 mm stroke. With a 50 mm bore, it generates a push force of 982 N at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa, making it suitable for medium-duty automation tasks.
This non-standard stroke model extends beyond the standard 1200 mm maximum for the 50 mm bore, built on a 150 mm body length (A) with a 20 mm diameter piston rod. The cylinder features an adjustable pneumatic cushion (21 mm length) to decelerate the piston at end-of-stroke, reducing impact noise and vibration in long-cycle applications.

Where the Airtac SC50 Standard Cylinder SC50X1400 Is Used
Long-Reach Material Transfer
Pushes or pulls components across wide conveyor gaps or between distant workstations, leveraging the extended 1400 mm stroke for single-cylinder transfer operations.
Automated Door & Gate Actuation
Operates large sliding guards, machine doors, or hopper gates in industrial machinery, using the adjustable cushion to ensure quiet, controlled end-of-stroke stopping.
Vertical Lift Assistance
Assists in raising or lowering platforms in compact lifting frames where a long stroke is needed but space constraints limit the use of larger bore cylinders.
Is the Airtac SC50 Standard Cylinder SC50X1400 the Right Cylinder?
Select the SC50X1400 when your application demands a stroke length exceeding the standard 1200 mm limit for 50 mm bore cylinders. If the 982 N push force at 0.5 MPa is insufficient, consider stepping up to the SC63 bore, which provides 1559 N at the same pressure. For applications requiring lower force, the SC40 bore delivers 628 N.
At 1400 mm stroke, the piston rod is highly extended. Side loads or misalignment can cause rod bending or bearing wear. Always use an external guide rail or rod-alignment coupler to absorb transverse forces, preventing premature seal failure and ensuring consistent linear motion.
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 SC50X1400 FAQ
At the standard operating pressure of 0.7 MPa, the push force is 1374 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
For strokes exceeding 300 mm, especially with a 20 mm rod, side loading must be avoided. Install an external linear guide or rod support to carry the transverse load. The cylinder should only provide axial push/pull force; any bending moment on the rod will damage the bearing and seals.
