About the Airtac SC50 Standard Cylinder SC50X290
The AirTAC SC50X290 is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). With a 50 mm bore, 20 mm piston rod, and M16x1.5 rod thread, it provides a balanced force-to-size ratio for medium-duty linear actuation at a 290 mm stroke.
This model features a 150 mm body length (A dimension) plus stroke, adjustable air cushioning for smooth end-of-stroke deceleration, and PT1/4 ports. The standard TPU seals suit operating temperatures from -20 to +70 °C, making it a reliable workhorse for general industrial automation.

Where the Airtac SC50 Standard Cylinder SC50X290 Is Used
Material Handling Gates
Actuates diverter gates and stops on conveyor lines. The 982 N push force at 0.5 MPa reliably moves medium-weight packages and totes.
Clamping & Fixturing
Provides consistent clamping pressure for woodworking or metal fab jigs. The 290 mm stroke accommodates deeper workpieces with adjustable cushioning for a soft close.
Packaging Presses
Drives a pressing platen in case sealers or compact balers. The tie-rod design allows easy maintenance in dusty packaging environments.
Is the Airtac SC50 Standard Cylinder SC50X290 the Right Cylinder?
For applications needing a bit more force, consider stepping up to the 63 mm bore (1559 N at 0.5 MPa). If space is tight and less force is acceptable, the 40 mm bore (628 N at 0.5 MPa) is a compact alternative. The 290 mm stroke is within the 1200 mm maximum standard stroke for this bore.
When replacing an existing cylinder, match five points: 50 mm bore, 290 mm stroke, PT1/4 port thread, basic mounting (no bracket), and ensure the magnet option (-S) matches your sensor setup. For strokes over 300 mm on a 20 mm rod, watch for side loading—this 290 mm unit is near that threshold; consider an external guide if any lateral force is present.
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 SC50X290 FAQ
At 0.5 MPa, the push force is 982 N and pull force is 825 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. Only replace another AirTAC SC tie-rod cylinder with matching bore, stroke, port thread, and mounting.
