About the Airtac SC50 Standard Cylinder SC50X800
The AirTAC SC50X800 is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 20 mm diameter piston rod and 800 mm stroke make it a strong candidate for medium-duty linear transfer tasks where extended reach is needed without stepping up to a larger bore.
With a body length of 150 mm, the total extended length reaches 950 mm. The cylinder features an adjustable pneumatic cushion (21 mm) at both ends to decelerate the piston smoothly, reducing end-of-stroke impact. This model uses the default PT1/4 port and TPU seals for standard operation from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X800 Is Used
Long-Reach Part Transfer
Moves components between distant conveyor stations or indexing tables. The 800 mm stroke bridges wide gaps, and 982 N of push force handles moderate payloads reliably.
Automated Gluing & Dispensing
Extends a dispensing head across a large panel or workpiece. Smooth cushioning prevents vibration at stroke end, ensuring a clean, precise bead of adhesive or sealant.
Vertical Lift Gate Actuation
Operates a tall lift gate or hopper door in material handling. The double-acting control provides powered opening and closing, with the adjustable cushion softening the stop at each end of travel.
Is the Airtac SC50 Standard Cylinder SC50X800 the Right Cylinder?
For applications needing more force, the SC63 bore provides 1559 N at 0.5 MPa, while the SC40 bore offers 628 N if a smaller footprint is acceptable. At an 800 mm stroke, ensure the rod is protected from side loads; external guides or a self-guided cylinder are recommended to prevent rod bending and premature bearing wear.
When replacing an existing cylinder, match five key points: 50 mm bore, 800 mm stroke, PT1/4 port thread, basic mounting (no brackets), and the absence of a built-in magnet. This ensures a direct dimensional and performance drop-in for another AirTAC SC50 tie-rod unit.
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 SC50X800 FAQ
At the standard operating pressure of 0.5 MPa, the push force is 982 N. At 0.7 MPa, it increases to 1374 N. The maximum theoretical force at 1.0 MPa is 200 kgf, though the recommended operating range is 0.15–1.0 MPa.
For a stroke of 800 mm with a 20 mm rod, side loads must be avoided. The rod is designed for axial push/pull forces. If any lateral force is present, an external guide rail or rod-alignment coupler is required to prevent rod bending, seal damage, and premature bearing failure.
