About the Airtac SC50 Standard Cylinder SC50X1000
The AirTAC SC50X1000 is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa, scaling up to 1767 N at the maximum operating pressure of 0.9 MPa. Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable end-of-stroke deceleration for medium-duty linear tasks.
With a 1000 mm stroke, this model reaches the maximum standard stroke for the 50 mm bore series. The compact tie-rod design, with a body length A of 150 mm, makes it a shorter alternative to ISO 15552 cylinders, suitable for space-constrained installations requiring a long working reach.

Where the Airtac SC50 Standard Cylinder SC50X1000 Is Used
Long-Reach Part Transfer
The 1000 mm stroke moves components between distant conveyor stations or work cells, using the 20 mm rod to handle medium payloads across wide gaps.
Vertical Lift Gate Actuation
Provides the linear motion for raising and lowering tall warehouse doors or vertical lift gates, with the adjustable cushion softening the stop at each end of the long travel.
Material Pusher on Long Roller Beds
Pushes boxes or pallets across extended roller beds in packaging lines, where the 982 N push force at standard pressure handles sliding friction over a meter-long path.
Is the Airtac SC50 Standard Cylinder SC50X1000 the Right Cylinder?
For applications needing more force, stepping up to the 63 mm bore provides 1559 N at 0.5 MPa, while the 40 mm bore offers 628 N for lighter, more compact designs. At a 1000 mm stroke, ensure the rod is protected from side loads; consider an external linear guide or a guided cylinder variant to prevent rod bearing damage and bending.
When replacing an existing cylinder, match five key points: 50 mm bore, 1000 mm stroke, PT1/4 port thread, the specific mounting accessory (this is a basic body mount), 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 SC50X1000 FAQ
At 0.7 MPa (7 bar) supply pressure, the SC50X1000 cylinder generates a theoretical push force of 1374 N. The retract (pull) force at the same pressure is 825 N due to the rod area reduction.
For a 1000 mm stroke, an external guide is strongly recommended if the load applies any side force or is not perfectly aligned. The 20 mm rod is susceptible to bending under side load at full extension; an external guide rail or rod support prevents premature seal and bearing wear.
