About the Airtac SC50 Standard Cylinder SC50X250SN
The AirTAC SC50X250SN is a 50 mm bore double-acting pneumatic cylinder with a 250 mm stroke, delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. The 20 mm diameter piston rod with M16x1.5 male threads provides robust linear actuation for medium-duty tasks. This model includes a built-in magnet, enabling direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors for precise end-of-stroke detection without external brackets.
Equipped with NBR (nitrile) seals, this cylinder is well-suited for applications where standard temperature ranges and resistance to oils and greases are required. The body length A is 150 mm, resulting in a total extended length of approximately 400 mm. The adjustable pneumatic cushion, with a 21 mm cushion length, effectively decelerates the piston at both ends of the stroke, reducing impact and noise for smoother operation.

Where the Airtac SC50 Standard Cylinder SC50X250SN Is Used
Material Handling
Pushing or diverting medium-weight packages and products on conveyor lines, where the 982 N force at 0.5 MPa provides ample power for gates and stops.
Clamping & Pressing
Operating jigs, fixtures, and light-duty presses in manufacturing cells, using the sensor-ready magnet for cycle confirmation and automation integration.
Machine Automation
Actuating guards, interlocks, and tool changers on automated machinery, where NBR seals offer good compatibility with common industrial lubricants.
Is the Airtac SC50 Standard Cylinder SC50X250SN the Right Cylinder?
For applications requiring slightly less force, stepping down to the 40 mm bore SC40 series provides 628 N of push force at 0.5 MPa. If higher force is needed, the 63 mm bore SC63 series offers a significant jump to 1559 N at the same pressure. This SC50X250SN cylinder is a direct replacement only for another AirTAC SC50 tie-rod cylinder of the same 250 mm stroke, PT port thread, and built-in magnet configuration. When replacing, always match bore, stroke, port thread, magnet option, and mounting accessory to ensure correct fit and function. For strokes of 250 mm, the standard rod support is generally adequate for axial loads, but any significant side loading requires an external guide or a guided cylinder to prevent rod bending and premature seal wear.
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 SC50X250SN FAQ
At the standard operating pressure of 0.5 MPa, 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 that is physically shorter than an ISO 15552 profile cylinder of the same bore and stroke. It is not dimensionally interchangeable with ISO 15552 cylinders. It is a direct replacement for another AirTAC SC50 cylinder with matching stroke, PT ports, and a built-in magnet.
