About the Airtac SC50 Standard Cylinder SC50X225SCB
The SC50X225SCB is a double-acting pneumatic cylinder with a 50 mm bore and 225 mm stroke, delivering a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range automation tasks.
This model is configured with a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors and a rear double clevis (CB) mount for pivoting applications. The standard PT ports and TPU seals suit general industrial environments with operating temperatures from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X225SCB Is Used
Conveyor Diverter Gates
The 982 N push force at 0.5 MPa and rear clevis mount allow the cylinder to pivot a diverter gate on a packaging or sorting conveyor, reliably redirecting products with a 225 mm stroke.
Clamping & Fixturing
With a built-in magnet for end-of-stroke sensing, this cylinder is ideal for automated clamping fixtures in CNC machining or welding cells, confirming part presence before a cycle starts.
Agricultural Equipment Actuation
The rear double clevis mount handles misalignment on mobile equipment like harvesters or spreaders, actuating chutes or gates with a robust 20 mm rod and 21 mm cushion.
Is the Airtac SC50 Standard Cylinder SC50X225SCB the Right Cylinder?
For applications requiring more force, stepping up to the 63 mm bore SC63 series provides a push force of 1559 N at 0.5 MPa. If a lower force profile is acceptable, the 40 mm bore SC40 series offers 628 N at the same pressure. The 225 mm stroke is within the 1200 mm standard maximum for this bore size.
When replacing an existing cylinder, ensure a 5-point match: 50 mm bore, 225 mm stroke, PT port thread, CB rear double clevis mounting, and the built-in magnet for sensor compatibility. For strokes of this length, avoid significant side loads on the rod; use an external guide or linear rail if the load is not purely axial to prevent rod bearing wear and bending.
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 SC50X225SCB FAQ
At 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 reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The SC50X225SCB is a double-acting cylinder that requires continuous air pressure to maintain its position. If pressure is lost or the directional valve is centered, the piston rod can drift or drop. For load holding, you must add a pilot-operated check valve or an external mechanical rod brake.
