About the Airtac SC50 Standard Cylinder SC50X625S
The AirTAC SC50X625S is a double-acting tie-rod cylinder with a 50 mm bore and a non-standard 625 mm stroke, factory-built with a built-in magnet for sensor mounting. Its 20 mm diameter piston rod delivers 982 N of push force at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa, making it suitable for medium-force linear tasks that require a longer reach.
This model features PT1/4 pneumatic ports and an M16x1.5 rod thread, with an adjustable air cushion of 21 mm at each end to decelerate the piston smoothly. The body length A is 150 mm, giving a total extended length of approximately 775 mm. Because the stroke exceeds the standard maximum of 1200 mm for this bore, it is a made-to-order item. The built-in magnet allows CMSG, DMSG, or EMSG sensors to clamp directly onto the tie-rod barrel for reliable end-of-stroke detection.

Where the Airtac SC50 Standard Cylinder SC50X625S Is Used
Long-Reach Part Transfer
The 625 mm stroke pushes or pulls components between distant conveyor lanes or workstations. The built-in magnet enables sensor confirmation of full extend and retract positions.
Automated Clamping with Sensor Feedback
Delivers up to 1767 N of clamping force at 0.9 MPa. The -S magnet lets CMSG/DMSG sensors verify the clamp is fully engaged before a machining cycle starts.
Bin Pushing or Diverting
Pushes totes or cartons off a main line onto a spur. The tie-rod construction handles repetitive impact when the cushion is correctly adjusted for the moving mass.
Is the Airtac SC50 Standard Cylinder SC50X625S the Right Cylinder?
Select the SC50 bore when your application needs between 982 N (push at 0.5 MPa) and 1767 N (push at 0.9 MPa). If you require higher force, step up to the SC63 bore, which provides 1559 N at 0.5 MPa. For a lighter, more compact solution, the SC40 bore delivers 628 N at 0.5 MPa. At 625 mm stroke, the unsupported rod length is significant; any side load will cause rod bending and accelerated bearing wear. Use an external linear guide or a guided cylinder to absorb transverse forces.
For a direct replacement, match these five attributes: 50 mm bore, 625 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic (no bracket) mounting configuration. This cylinder is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC50X625S FAQ
At 0.5 MPa (≈73 psi) the push force is 982 N. At 0.7 MPa (≈102 psi) it rises to 1374 N, and at the maximum operating pressure of 0.9 MPa (≈131 psi) it reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf. Pull force is lower due to the rod area: 825 N at 0.5 MPa.
Yes. The -S suffix means a magnet is built into the piston, so CMSG (reed) or DMSG/EMSG (solid-state) sensors clip onto the barrel. For the 625 mm stroke, never allow the rod to take side load—install an external guide rail or rod-alignment coupler to prevent bending and seal failure.
