About the Airtac SC50 Standard Cylinder SC50X1020S
The AirTAC SC50X1020 is a double-acting tie-rod cylinder with a 50 mm bore and a long 1020 mm stroke, delivering a push force of 982 N at 0.5 MPa (1374 N at 0.7 MPa). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for extended linear movements.
With a body length A of 150 mm, the total extended length reaches approximately 1170 mm. This model uses PT1/4 ports and an M16x1.5 rod thread, making it a direct replacement for other SC50 tie-rod cylinders with matching specifications.

Where the Airtac SC50 Standard Cylinder SC50X1020S Is Used
Long-Reach Part Transfer
The 1020 mm stroke moves components across wide conveyor gaps or between distant workstations in automated assembly lines.
Material Pusher in Sawmills
Pushes lumber or sheet goods onto processing tables, using the 982 N force at 0.5 MPa for consistent feed without stalling.
Ventilation Damper Actuation
Opens and closes large air-handling dampers in agricultural buildings, where the long stroke provides full range of motion for airflow control.
Is the Airtac SC50 Standard Cylinder SC50X1020S the Right Cylinder?
Choose the SC50X1020 when your application needs the 50 mm bore's 982 N push at 0.5 MPa. If you require more force, step up to the SC63 bore which provides 1559 N at the same pressure. For lower force requirements, the SC40 bore offers 628 N.
This 1020 mm stroke is within the 1200 mm maximum standard stroke for the 50 mm bore. For strokes of this length, always check for potential side loading on the 20 mm rod. An external guide or guided cylinder is recommended to prevent rod bending and ensure long seal life. When replacing, match bore, stroke, PT port thread, basic mounting, and the absence of a 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 SC50X1020S 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. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The SC series is a tie-rod cylinder that is shorter than an ISO 15552 cylinder, so it is not dimensionally interchangeable. It directly replaces other AirTAC SC50 tie-rod cylinders with the same bore, stroke, PT port, and basic mounting.
