About the Airtac SC50 Standard Cylinder SC50X270
The SC50X270 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering 982 N of push force and 825 N of pull force at 0.5 MPa. With a 50 mm bore and 270 mm stroke, it suits medium-force linear actuation tasks where a compact body length is needed.
This model features a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion at each end is 21 mm long, helping to decelerate the piston smoothly. The total extended body length is approximately 420 mm (150 mm body length A plus the 270 mm stroke).

Where the Airtac SC50 Standard Cylinder SC50X270 Is Used
Part Rejection Gates
Provides the 982 N push force needed to divert medium-weight packages off a conveyor line, with the 270 mm stroke clearing the full belt width.
Clamping & Fixturing
Used in woodworking or light metalworking jigs where a 270 mm stroke clamps workpieces of varying thicknesses with consistent force.
Hopper Door Actuation
Opens and closes discharge doors on seed or grain hoppers, handling the 825 N pull force needed to slide a gate against material weight.
Is the Airtac SC50 Standard Cylinder SC50X270 the Right Cylinder?
For applications needing slightly less force, the 40 mm bore SC40 series provides 628 N push at 0.5 MPa. If higher force is required, stepping up to the 63 mm bore SC63 delivers 1559 N at the same pressure. Always match bore, stroke, PT port thread, and mounting style when replacing an existing cylinder.
At a 270 mm stroke, the 20 mm rod is well-supported for axial loads, but any significant side loading requires an external linear guide or a guided cylinder variant to prevent rod bending and premature bearing 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 SC50X270 FAQ
At the standard 0.5 MPa operating pressure, 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.
No. The SC50X270 is a double-acting cylinder and will drift or drop if pressure is lost or the directional valve is centered. For position holding without live pressure, you must add an external rod brake or a pilot-operated check valve.
