About the Airtac SC50 Standard Cylinder SC50X515
The AirTAC SC50X515 is a double-acting tie-rod cylinder with a 50 mm bore and a non-standard 515 mm stroke, built for applications needing extended linear reach. At 0.5 MPa it provides 982 N of push force and 825 N pull, rising to 1767 N at the 0.9 MPa maximum operating pressure, while the 20 mm diameter piston rod and 21 mm adjustable air cushion ensure controlled deceleration.
With a body length A of 150 mm, the total extended length reaches approximately 665 mm. This genuine AirTAC SC cylinder uses PT1/4 ports and operates on filtered air from 0.15 to 1.0 MPa, with TPU seals rated for -20 to +70 °C. The long stroke demands attention to side-load management—external guides are recommended to protect the rod bearing.

Where the Airtac SC50 Standard Cylinder SC50X515 Is Used
Long-Reach Material Handling
Pushes or pulls bins, gates, or diverters across extended distances on packaging and assembly lines where a 500+ mm stroke is essential.
Automated Pressing & Clamping
Delivers up to 1767 N at 0.9 MPa for holding, pressing, or clamping operations that require a deep throat or long tooling clearance.
Agricultural Machinery Actuation
Operates chute doors, sorting gates, or tensioning arms on farm equipment, leveraging the TPU seals' -20 °C low-temperature tolerance.
Is the Airtac SC50 Standard Cylinder SC50X515 the Right Cylinder?
Choose the SC50X515 when your stroke requirement exceeds the standard 500 mm maximum for 32 mm bore cylinders but you need the force class of a 50 mm bore. If 982 N at 0.5 MPa is insufficient, step up to the SC63 series which delivers 1559 N push at the same pressure; if the force is adequate but you need a standard stroke, the SC50X500 is the nearest off-the-shelf alternative.
For strokes of 300 mm or more, side loads become a critical design factor. The 20 mm rod on this 515 mm stroke cylinder can experience bending under off-axis forces—install an external linear guide or consider a guided cylinder to protect the rod bearing and extend service life. When replacing an existing unit, match all five key points: 50 mm bore, 515 mm stroke, PT1/4 port thread, basic mounting (no bracket), 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 SC50X515 FAQ
At 0.5 MPa (approximately 72 psi) the cylinder produces 982 N pushing force and 825 N pulling force. At the maximum operating pressure of 0.9 MPa, the push force increases to 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 body length than ISO 15552 profile cylinders, so mounting dimensions and overall length differ. It is a direct replacement only for another AirTAC SC tie-rod cylinder with identical 50 mm bore, 515 mm stroke, PT ports, and basic mounting.
