About the Airtac SC50 Standard Cylinder SC50X325N
The AirTAC SC50X325N is a double-acting tie-rod cylinder with a 50 mm bore and 325 mm stroke, fitted with NBR (nitrile) seals. It provides a push force of 982 N at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa, driven by a 20 mm diameter piston rod.
This cylinder uses a PT1/4 port and an M16x1.5 rod thread, with a 21 mm adjustable air cushion at each end to decelerate the piston smoothly. The body length A is 150 mm, giving a total extended length of approximately 475 mm. It operates on filtered air within a pressure range of 0.15–1.0 MPa and a standard speed range of 30–800 mm/s.

Where the Airtac SC50 Standard Cylinder SC50X325N Is Used
Material Sorting Gate
Actuates a diverter gate on a conveyor line. The 982 N force at 0.5 MPa is sufficient to reliably push packages onto a secondary lane, while the NBR seals offer good wear resistance in continuous cycling.
Clamping Fixture
Provides the holding force for a machining or welding jig. The 325 mm stroke allows the clamp arm to retract fully for easy part loading, and the adjustable cushion prevents impact vibration that could disturb the workpiece.
Agricultural Equipment Actuator
Operates a chute or flow-control mechanism on farming machinery. The NBR seals are compatible with many agricultural lubricants, and the tie-rod design is easy to service in the field.
Is the Airtac SC50 Standard Cylinder SC50X325N the Right Cylinder?
For applications needing slightly more force, stepping up to the 63 mm bore SC63 series provides 1559 N of push force at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the 40 mm bore delivers 628 N at the same pressure. At 325 mm stroke, the rod is well-supported within standard limits, but any significant side load should be managed with an external linear guide to protect the rod bearing and piston seals.
To ensure a correct replacement, match five key points: 50 mm bore, 325 mm stroke, PT port thread, NBR seal material, and the basic (no bracket) mounting configuration. This model does not include a built-in magnet, so it is not directly compatible with clamp-on magnetic sensors unless an external switch mounting solution is devised.
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 SC50X325N FAQ
The theoretical push force is 982 N at 0.5 MPa, 1374 N at 0.7 MPa, and 1767 N at the maximum operating pressure of 0.9 MPa. The pull force on the return stroke is 825 N at 0.5 MPa due to the area reduction from the 20 mm piston rod.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than a comparable ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552 mounts. It is a direct replacement only for another AirTAC SC 50 mm bore cylinder with matching stroke, port thread, and mounting.
