About the Airtac SC50 Standard Cylinder SC50X320
The SC50X320 is a double-acting pneumatic cylinder delivering 982 N of push force and 825 N of pull force when operated at 0.5 MPa. Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range automation tasks, with a body length A of 150 mm making it compact for its class.
At the maximum operating pressure of 0.9 MPa, this 50 mm bore unit generates 1767 N of thrust, suitable for pressing, clamping, and material transfer. The 320 mm stroke is well within the 1200 mm maximum standard stroke for this bore, ensuring standard lead times and full parts availability.

Where the Airtac SC50 Standard Cylinder SC50X320 Is Used
Package Sorting Gates
The 320 mm stroke and 982 N push force at 0.5 MPa reliably divert cartons and totes on conveyor lines, with the adjustable cushion softening end-of-stroke impact for quiet, low-wear operation.
Automated Fixture Clamping
Delivers 1767 N of clamping force at 0.9 MPa for CNC workholding and assembly jigs. The 20 mm rod diameter provides rigidity for precise, repeatable part positioning over the 320 mm stroke.
Pallet Layer Forming
Used in palletising cells to push or align layers of boxes. The double-acting SC50X320 provides controlled, bidirectional motion with 825 N of pull force for retracting tooling.
Is the Airtac SC50 Standard Cylinder SC50X320 the Right Cylinder?
For applications needing more force, stepping up to the 63 mm bore (SC63 series) provides 1559 N of push force at 0.5 MPa. If space is tight and less force is acceptable, the 40 mm bore (SC40) offers 628 N. This 320 mm stroke cylinder should be protected from side loads; use an external guide rail or rod-alignment coupler to prevent rod bending and premature bearing wear.
To ensure a correct replacement, match five key points: 50 mm bore, 320 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and the absence of a built-in magnet. This model uses the standard TPU seal and PT thread configuration.
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 SC50X320 FAQ
At the standard 0.5 MPa operating pressure, the push force is 982 N and the pull force is 825 N. At 0.7 MPa, push force increases to 1374 N, and at the maximum operating pressure of 0.9 MPa, it reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No, the SC50X320 is a double-acting cylinder and will not hold its position if air pressure is exhausted or the directional valve is centred. The piston will drift or drop under load. For load-holding, you must add a pilot-operated check valve, a mechanical rod lock, or an external brake.
