About the Airtac SC50 Standard Cylinder SC50X425S
The SC50X425S is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at the maximum operating pressure of 0.9 MPa). Its 50 mm bore and 425 mm stroke suit medium-force linear tasks where a compact tie-rod body is preferred. The rod diameter is 20 mm with an M16x1.5 male thread, and the adjustable air cushion (21 mm length) decelerates the piston smoothly at both ends.
The integrated magnet (-S suffix) allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for non-contact position sensing. This model uses the standard TPU/NBR seal package rated for -20 to +70 °C and PT1/4 port threads. The body length A is 150 mm, giving a total extended length of approximately 575 mm.

Where the Airtac SC50 Standard Cylinder SC50X425S Is Used
Conveyor Diverters
The 425 mm stroke and 982 N push force at 0.5 MPa reliably shift medium-weight packages or totes on conveyor lines, with the built-in magnet confirming end-of-stroke position.
Clamping & Assembly Jigs
Delivers consistent clamping pressure for woodworking or light metal assembly fixtures. The adjustable cushion reduces impact noise and vibration at the end of the 425 mm travel.
Material Lifting Gates
Operates vertical lift gates or chutes in material handling systems. The double-acting design provides powered retraction, and the magnet enables interlock signals for automated control.
Is the Airtac SC50 Standard Cylinder SC50X425S the Right Cylinder?
For higher force at the same pressure, step up to the 63 mm bore (1559 N at 0.5 MPa); for a lighter, more compact actuator, the 40 mm bore provides 628 N. At a 425 mm stroke, the 20 mm rod is well-supported inside the barrel, but any significant side load should be managed with an external linear guide or a guided cylinder to protect the rod bearing and piston seals. When replacing an existing unit, match five points: 50 mm bore, 425 mm stroke, PT1/4 port thread, the built-in magnet for sensor compatibility, and the basic (no bracket) 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 SC50X425S FAQ
At 0.5 MPa supply pressure, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
Yes. The -S suffix indicates a built-in magnet on the piston. This allows AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors to be clamped onto the barrel's tie-rod slots for precise, non-contact position detection at any point along the stroke.
