About the Airtac SC50 Standard Cylinder SC50X310
The SC50X310 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-stroke positioning tasks, making it a solid choice for general automation requiring a 310 mm linear movement.
Built on a proven tie-rod design with a 150 mm body length, this cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard. The standard PT1/4 ports and M16x1.5 rod thread ensure straightforward pneumatic connections for factory automation equipment.

Where the Airtac SC50 Standard Cylinder SC50X310 Is Used
Material Transfer
Pushes or diverts boxes and totes on a conveyor line. The 310 mm stroke reaches across standard roller beds, and the 21 mm cushion absorbs impact at the end of travel.
Clamping & Fixturing
Applies consistent 982 N clamping force at 0.5 MPa for holding parts during welding or assembly. The adjustable cushion prevents vibration that could disturb part alignment.
Packaging Ejector
Ejects finished packages from a filling station. The double-acting function ensures positive retraction for the next cycle, maintaining a steady 30-800 mm/s speed range.
Is the Airtac SC50 Standard Cylinder SC50X310 the Right Cylinder?
For applications needing more force, stepping up to the 63 mm bore SC63 series provides 1559 N of push force at the same 0.5 MPa pressure. This 310 mm stroke is within the standard range for the 50 mm bore, which supports up to 1200 mm. When a stroke exceeds 300 mm, ensure the rod is not subjected to side loads; use an external guide or a guided cylinder if the load is not perfectly axial to prevent rod bending and premature bearing wear.
To match this cylinder for a replacement, confirm five points: 50 mm bore, 310 mm stroke, PT1/4 port thread, basic mounting (no bracket), and no built-in magnet. The SC50X310 is a direct swap only for another AirTAC SC50 tie-rod cylinder with these identical specifications.
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 SC50X310 FAQ
At 0.7 MPa operating pressure, the SC50X310 produces 1374 N of push force and a proportional pull force based on the 20 mm rod area. The maximum push force at 0.9 MPa is 1767 N. These values assume a clean, filtered air supply at the rated pressure.
No. The SC50X310 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 can drift. For load holding without live pressure, you must add an external rod brake or a pilot-operated check valve.
