About the Airtac SC50 Standard Cylinder SC50X1200
The SC50X1200 is a double-acting tie-rod cylinder delivering a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and a 1200 mm stroke, this model reaches the maximum standard stroke length for this bore size, making it suitable for long-transfer linear applications.
This cylinder features a 20 mm diameter piston rod with an M16x1.5 knuckle thread and PT1/4 ports. The adjustable pneumatic cushion at each end is 21 mm long, designed to decelerate the piston smoothly. The body length A is 150 mm, resulting in a total extended length of approximately 1350 mm.

Where the Airtac SC50 Standard Cylinder SC50X1200 Is Used
Long-Reach Material Transfer
Pushes or pulls components across a 1200 mm span on packaging or assembly lines, ideal for diverters and long-stroke part shuttles.
Automated Gluing & Dispensing
Provides the extended linear travel needed for applying a continuous bead of adhesive or sealant along large panels or profiles.
Palletising & Stacking
Drives a pusher plate across a wide conveyor to align or offload boxes and totes in end-of-line logistics equipment.
Is the Airtac SC50 Standard Cylinder SC50X1200 the Right Cylinder?
For applications requiring less force at this stroke, consider stepping down to the 40 mm bore (628 N at 0.5 MPa). If higher force is needed, the 63 mm bore provides 1559 N at the same pressure. At a 1200 mm stroke, the unsupported rod is susceptible to bending under side loads; an external linear guide or a guided cylinder configuration is strongly recommended to protect the rod bearing and seal.
To ensure a correct replacement, match five points: 50 mm bore, 1200 mm stroke, PT1/4 port thread, the specific mounting accessory (this basic model has none), and the magnet option (this model has no built-in magnet).
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 SC50X1200 FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N.
A 1200 mm stroke creates a long moment arm that can damage the rod bearing under side load. Always use an external linear guide rail to absorb lateral forces, or switch to a guided cylinder assembly.
