About the Airtac SC50 Standard Cylinder SC50X300S
The AirTAC SC50X300S is a double-acting tie-rod cylinder with a 50 mm bore and 300 mm stroke, pre-fitted with a built-in magnet for direct mounting of CMSG, DMSG, or EMSG sensors. This model delivers 982 N of push force and 825 N of pull force when operated at 0.5 MPa, making it a dependable workhorse for mid-range pneumatic tasks.
With a 20 mm diameter piston rod and M16x1.5 rod thread, the cylinder provides solid mechanical connection for tooling. The adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly, reducing end-of-stroke impact. The body length A is 150 mm, giving a total extended length of approximately 450 mm for this 300 mm stroke unit.

Where the Airtac SC50 Standard Cylinder SC50X300S Is Used
Part Diverting Gate
Actuates a diverter flap on a conveyor line. The 982 N push force at 0.5 MPa reliably shifts packages or components between lanes, while the magnetic piston enables end-of-stroke sensing for PLC integration.
Clamping & Fixturing
Powers a pneumatic clamp in a machining or welding fixture. The 300 mm stroke provides ample retraction for part loading, and the built-in magnet allows sensors to confirm clamp engagement before the cycle starts.
Box Flap Folding
Drives a folding arm on a case erector or pack station. The adjustable cushion ensures a quiet, low-impact stroke end, and the sensor-ready barrel confirms the arm is home, preventing misfeeds.
Is the Airtac SC50 Standard Cylinder SC50X300S the Right Cylinder?
This 50 mm bore cylinder suits applications needing up to 982 N at standard plant pressure. If your force requirement is lower, stepping down to a 40 mm bore (628 N push at 0.5 MPa) saves space and air consumption. For higher force, the 63 mm bore delivers 1559 N at the same pressure.
At 300 mm of stroke, the 20 mm rod is well-supported within its standard range, but any significant side load still demands an external guide or a guided cylinder to protect the rod bearing from bending and premature seal wear. When replacing an existing unit, match five points: 50 mm bore, 300 mm stroke, PT port thread, the built-in magnet (-S suffix), and the basic mounting style (no bracket).
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 SC50X300S FAQ
At 0.5 MPa, the cylinder provides 982 N push force and 825 N pull force. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
Yes. The -S suffix indicates a built-in magnet in the piston. This allows AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors to be clamped directly onto the barrel's tie-rod slots without any additional brackets or modifications.
