About the Airtac SC50 Standard Cylinder SC50X520
The SC50X520 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 50 mm bore with a 520 mm stroke. At 0.5 MPa it provides 982 N of push force and 825 N of pull force, making it a capable mid-range actuator for linear transfer and pressing tasks.
This model uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The total extended body length is approximately 670 mm (150 mm body length A + 520 mm stroke). Its adjustable air cushion, with a 21 mm cushion length, decelerates the piston smoothly at both ends of the stroke.

Where the Airtac SC50 Standard Cylinder SC50X520 Is Used
Part Transfer & Indexing
Moves components between conveyor lanes or workstations with a 520 mm linear stroke, using the 982 N push force to shift totes or fixtures reliably.
Light Press & Clamping
Applies controlled clamping pressure in assembly jigs. The adjustable cushion prevents impact damage when the tooling contacts the part at speed.
Material Feed Systems
Pushes bar stock or sheet material into a CNC machine. The 20 mm rod and tie-rod construction handle repetitive feed cycles in dusty shop environments.
Is the Airtac SC50 Standard Cylinder SC50X520 the Right Cylinder?
Select the SC50X520 when your application needs roughly 980 N of force at standard shop air. If you need more force, stepping up to a 63 mm bore (SC63) provides 1559 N push at the same 0.5 MPa. For lighter, faster cycling, the 40 mm bore (SC40) delivers 628 N.
For a 520 mm stroke, ensure the rod is protected from side loads. Long, unsupported strokes on a 20 mm rod can experience bending moments; use an external linear guide or rod-alignment coupler to prevent bearing wear and seal damage. When replacing an existing cylinder, match five points: 50 mm bore, 520 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and the standard TPU seal.
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 SC50X520 FAQ
At 0.7 MPa operating pressure, the SC50X520 produces 1374 N of push force and 1155 N of pull force (calculated from the 50 mm bore thrust table). The maximum operating force at 0.9 MPa is 1767 N push.
This standard SC50X520 model does not include a built-in magnet. To use CMSG or DMSG sensors for piston position detection, order the SC50X520-S variant, which adds a magnetic ring to the piston. Sensors then clamp directly onto the tie-rod barrel.
