About the Airtac SC50 Standard Cylinder SC50X400SLB
The SC50X400SLB is a 50 mm bore double-acting pneumatic cylinder delivering a push force of 982 N at 0.5 MPa (1767 N at 0.9 MPa). With a 400 mm stroke and a 20 mm diameter piston rod, it handles mid-range linear actuation tasks where moderate force and a medium travel distance are required.
This model includes a built-in magnet (-S) for mounting CMSG/DMSG/EMSG sensors directly on the tie-rod barrel, and ships with LB axial foot mounts (F-SC50LB) for secure surface installation. The adjustable air cushion (21 mm) decelerates the piston smoothly, and the standard PT1/4 port thread ensures straightforward pneumatic connections.

Where the Airtac SC50 Standard Cylinder SC50X400SLB Is Used
Material Stops & Gates
The 982 N push force and 400 mm stroke reliably actuates pop-up stops and divert gates on medium-duty package handling conveyors.
Clamping & Fixturing
Provides consistent clamping pressure for woodworking or light metal fabrication jigs, with the LB foot mount simplifying bench-top integration.
Hopper Door Actuation
Operates slide gates or diverter flaps on agricultural bins and chutes, where the magnet sensors confirm open/closed position for automated sequencing.
Is the Airtac SC50 Standard Cylinder SC50X400SLB the Right Cylinder?
Choose the SC50X400SLB when your application needs around 982 N of push force at standard shop air. If you require significantly more force, stepping up to the 63 mm bore (1559 N at 0.5 MPa) is advisable; for lighter, faster cycling, the 40 mm bore (628 N) may be a better fit. For strokes of 300 mm or longer, always evaluate side-load conditions—an unsupported 20 mm rod extending 400 mm is vulnerable to bending under radial force; use an external guide or switch to a guided cylinder if side loads are present.
To replace an existing cylinder, match five key points: 50 mm bore, 400 mm stroke, PT1/4 port thread, LB foot mounting, and the integrated magnet for sensor compatibility. This tie-rod design is shorter than an ISO 15552 cylinder, so dimensional interchangeability is limited to other AirTAC SC series units with the same 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 SC50X400SLB FAQ
At 0.5 MPa the cylinder provides 982 N pushing force and 825 N pulling force. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The -S suffix indicates a built-in magnet, so you can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel to detect piston position without additional brackets.
