About the Airtac SC50 Standard Cylinder SC50X500
The SC50X500 is a 50 mm bore double-acting tie-rod cylinder delivering a push force of 982 N at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa. Its 500 mm stroke is well within the 1200 mm maximum standard stroke for this bore, making it a balanced choice for medium-reach linear tasks.
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 provides a 21 mm deceleration zone to absorb kinetic energy quietly. The body length A is 150 mm, giving a total extended length of approximately 650 mm.

Where the Airtac SC50 Standard Cylinder SC50X500 Is Used
Package Sorting Gates
Actuates diverter gates on medium-speed conveyor lines. The 500 mm stroke provides ample reach to push cartons onto branch lanes, while the 982 N force at 0.5 MPa handles typical parcel weights reliably.
Clamping & Fixturing
Powers mechanical clamps on woodworking or light metalworking jigs. The adjustable cushion prevents impact vibration that could shift a workpiece, maintaining fixture accuracy during high-cycle clamping.
Hopper Door Actuation
Opens and closes discharge doors on bulk material hoppers. The double-acting control ensures positive opening and closing, preventing material bridging by delivering consistent 1767 N of force at full 0.9 MPa line pressure.
Is the Airtac SC50 Standard Cylinder SC50X500 the Right Cylinder?
Select the SC50X500 when your application needs roughly 100 kgf of push force. If your load requires more thrust, step up to the SC63 bore which provides 1559 N at 0.5 MPa; for a lighter, more compact solution, the SC40 bore offers 628 N at the same pressure.
At a 500 mm stroke, ensure side loads are minimal or use an external guide rod. Long unsupported strokes on a 20 mm rod can experience bending moments under eccentric loads. For direct replacement, match these five attributes: 50 mm bore, 500 mm stroke, PT port thread, basic mounting (no bracket), and the absence of a magnet sensor option.
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 SC50X500 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 AirTAC SC series is a tie-rod cylinder that is physically shorter than a comparable ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC or equivalent tie-rod cylinder matching the 50 mm bore, 500 mm stroke, PT1/4 ports, and basic mounting.
