About the Airtac SC50 Standard Cylinder SC50X530S
The AirTAC SC50X530S is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa), making it a strong mid-range actuator for medium-duty automation. With a 50 mm bore and a 530 mm stroke, this model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG sensors to clamp directly onto the barrel for precise, non-contact position sensing.
This cylinder uses a 20 mm diameter piston rod with an M16x1.5 thread and PT1/4 ports. The adjustable air cushion (21 mm length) decelerates the piston smoothly at both ends, protecting end caps and reducing noise. The body length A is 150 mm, giving a total extended length of approximately 680 mm. Operating pressure ranges from 0.15 to 1.0 MPa with a standard speed of 30-800 mm/s.

Where the Airtac SC50 Standard Cylinder SC50X530S Is Used
Material Transfer Gates
The 530 mm stroke and 982 N push force reliably actuate diverter gates on wide conveyor lines, with the magnetic piston enabling end-of-travel confirmation via barrel-mounted sensors.
Automated Welding Fixtures
Clamps and positions components in robotic welding cells. The built-in magnet provides sensor feedback to the PLC, ensuring the fixture is fully extended before the weld cycle starts.
Pallet Stop & Release
Controls the flow of heavy pallets on gravity or powered roller conveyors. The adjustable cushion absorbs impact energy smoothly as the 20 mm rod stops a moving pallet.
Is the Airtac SC50 Standard Cylinder SC50X530S the Right Cylinder?
For applications needing more force, stepping up to the 63 mm bore (SC63 series) provides 1559 N at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the 40 mm bore (628 N at 0.5 MPa) may reduce weight and air consumption. This 530 mm stroke is within the 1200 mm maximum standard stroke for the 50 mm bore.
At 530 mm of stroke, the 20 mm rod is susceptible to bending under significant side loads. For long-stroke applications, always guide the load externally with a linear rail or rod guide, or consider a guided cylinder assembly. For a direct replacement, match bore (50 mm), stroke (530 mm), PT1/4 port thread, the built-in magnet (-S), and the basic mounting 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 SC50X530S FAQ
At the standard operating pressure of 0.7 MPa, the push force is 1374 N and the pull force is 1155 N. The maximum push force at 0.9 MPa is 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf. Always select a cylinder based on a force 30-50% above your moving load for reliable acceleration.
Match five key specifications: 50 mm bore, 530 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix) for sensor compatibility, and the basic (footless) mounting. The SC series is a tie-rod design, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC tie-rod cylinders of the same bore and stroke.
