About the Airtac SC50 Standard Cylinder SC50X300N
The AirTAC SC50X300N is a double-acting tie-rod cylinder with a 50 mm bore and 300 mm stroke, fitted with NBR (nitrile) seals for general-purpose pneumatic applications. At 0.5 MPa it produces 982 N of push force and 825 N on the pull stroke, rising to 1767 N at the maximum operating pressure of 0.9 MPa.
This model uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The adjustable air cushion at each end (21 mm length) decelerates the piston smoothly, and the total extended body length is approximately 450 mm (150 mm body length A plus 300 mm stroke).

Where the Airtac SC50 Standard Cylinder SC50X300N Is Used
Material Handling Gates
The 300 mm stroke and 982 N push force at 0.5 MPa operate diverter gates and stops on package conveyors, moving cartons reliably with NBR seals suited for indoor ambient temperatures.
Clamping & Assembly Fixtures
Delivers 1767 N of clamping force at 0.9 MPa for holding workpieces during welding or assembly. The adjustable cushion reduces impact noise and vibration at the end of the 300 mm travel.
Agricultural Equipment Actuation
NBR seals provide good resistance to oils and greases commonly found in farm machinery. The 50 mm bore cylinder pushes or pulls linkages on seed drills and sprayer booms with a 300 mm working stroke.
Is the Airtac SC50 Standard Cylinder SC50X300N the Right Cylinder?
Choose the SC50 bore when your application needs roughly 980 N of force at standard shop air. If you can accept a smaller footprint, stepping down to the SC40 delivers 628 N at 0.5 MPa; for more power, the SC63 provides 1559 N at the same pressure. All mounting accessories from the F-SC50 series (LB, FA, FB, CA, CB, TC) fit this cylinder.
For a 300 mm stroke, confirm that the rod is guided externally or the load is purely axial. A 20 mm rod extended 300 mm is vulnerable to bending under side load—add an external guide rail or switch to a guided cylinder if the load is not perfectly in-line. When replacing an existing unit, match bore, stroke, PT port thread, NBR seal material, and basic mount type to ensure drop-in compatibility.
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 SC50X300N FAQ
At 0.7 MPa (7 bar) the SC50 double-acting cylinder generates 1374 N of push force on the piston and 825 N of pull force on the rod side, as listed in the official AirTAC SC series thrust table.
The SC50X300N uses NBR seals, which are oil-resistant and rated for -20 to +70 °C. If your original cylinder used TPU or Viton seals, check the operating temperature and fluid compatibility. For high-temperature environments up to 150 °C, order the SC50X300SH variant with Viton seals instead.
