About the Airtac SC50 Standard Cylinder SC50X350N
The AirTAC SC50X350N is a double-acting tie-rod cylinder delivering a push force of 1374 N at 0.7 MPa and 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and 350 mm stroke, this model uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The body length (A) is 150 mm, giving a total extended length of approximately 500 mm.
This variant is fitted with NBR (nitrile) seals, suitable for standard operating temperatures from -20 to +70 °C. The adjustable pneumatic cushion at each end, with a 21 mm cushion length, decelerates the piston to reduce end-of-stroke impact. As a genuine AirTAC SC cylinder, it provides a reliable, cost-effective solution for general industrial automation tasks requiring a mid-range force output.

Where the Airtac SC50 Standard Cylinder SC50X350N Is Used
Material Transfer
Pushes or lifts products between conveyor lines, where the 350 mm stroke bridges a gap and the 1374 N force at 0.7 MPa handles medium-weight totes.
Clamping & Fixturing
Applies consistent clamping pressure in a welding or assembly jig, using the adjustable cushion to gently contact the part without impact damage.
Farm Implement Actuation
Operates a gate or diverter chute on agricultural equipment, with NBR seals providing reliable performance in dusty, ambient-temperature environments.
Is the Airtac SC50 Standard Cylinder SC50X350N the Right Cylinder?
The SC50X350N suits applications needing a 350 mm stroke with 982 N of force at 0.5 MPa. If the load requires more force, stepping up to the 63 mm bore provides 1559 N at the same pressure. For lighter, faster cycles, the 40 mm bore offers 628 N. At this 350 mm stroke, ensure the rod is supported against side loads; an external guide or linear rail is recommended to prevent bending and premature seal wear on the 20 mm rod. When replacing this cylinder, match the 50 mm bore, 350 mm stroke, PT1/4 port thread, and NBR seal material exactly.
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 SC50X350N FAQ
At 0.5 MPa (5 bar), 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 increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than a standard ISO 15552 profile cylinder. It is not dimensionally interchangeable. Replace it only with another AirTAC SC50 cylinder matching the 350 mm stroke, PT1/4 ports, and NBR seals.
