About the Airtac SC50 Standard Cylinder SC50X424S
The AirTAC SC50X424S is a double-acting single-rod pneumatic cylinder engineered for mid-force linear tasks. With a 50 mm bore and 424 mm stroke, it generates 982 N of push force at 0.5 MPa (1767 N at the 0.9 MPa maximum operating pressure), driven by a 20 mm diameter piston rod with M16x1.5 male threads.
This model includes the factory-installed -S magnet embedded in the piston, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for contactless end-of-stroke detection. The adjustable air cushion at each end decelerates the 424 mm travel, and the body length A is 150 mm, giving a total extended length of approximately 574 mm.

Where the Airtac SC50 Standard Cylinder SC50X424S Is Used
Part Transfer
The 424 mm stroke pushes or lifts components between conveyor lanes. The built-in magnet enables sensor confirmation of extend and retract positions for reliable automation sequencing.
Clamping & Fixturing
Delivers up to 1767 N of clamping force at 0.9 MPa. The -S magnet lets you verify clamp engagement with a DMSG sensor before a machining cycle starts.
Bin Diverter
Use the mid-range stroke to divert packages on a gravity or powered roller line. The adjustable cushion protects the cylinder and product at the end of the fast 424 mm stroke.
Is the Airtac SC50 Standard Cylinder SC50X424S the Right Cylinder?
Select the SC50 bore when your application needs between 982 N and 1767 N of thrust from standard plant air. If your load is lighter and you want a more compact actuator, step down to the SC40 bore (628 N push at 0.5 MPa). For heavier work, the SC63 bore delivers 1559 N at the same pressure. At 424 mm of stroke, the 20 mm rod is well-supported, but any side loading should be managed with an external guide rail or rod-alignment coupler to protect the rod bearing and piston seals.
For a direct replacement, match five attributes: 50 mm bore, 424 mm stroke, PT port thread, the built-in magnet (-S suffix), and the basic mounting style. This cylinder is a tie-rod design and 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 SC50X424S FAQ
At 0.5 MPa the cylinder pushes with 982 N and pulls with 825 N. At 0.7 MPa push rises to 1374 N, and at the maximum operating pressure of 0.9 MPa it reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The -S suffix indicates a magnet is built into the piston. You can clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel to detect piston position without any additional brackets.
