About the Airtac SC50 Standard Cylinder SC50X350SCB
The SC50X350SCB is a double-acting AirTAC SC tie-rod cylinder with a 50 mm bore and 350 mm stroke, delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). The built-in magnet allows CMSG/DMSG/EMSG sensors to be clamped directly onto the barrel for reliable end-of-stroke detection without external brackets.
This model is configured with a CB rear double clevis mount (fork), part code F-SC50CB, which handles pivoting loads effectively. The 20 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration. The total extended body length is approximately 500 mm (150 mm body length A + 350 mm stroke).

Where the Airtac SC50 Standard Cylinder SC50X350SCB Is Used
Agricultural Machinery
Operates pivot-mounted gates or chutes on harvesters and planters, where the rear double clevis allows the cylinder to swing freely as the mechanism articulates.
Conveyor Diverters
Drives a pivoting diverter arm on a packaging or sortation conveyor. The magnet confirms the arm has fully extended or retracted, preventing product jams.
Welding Fixture Clamping
Clamps components in a welding jig with a pivoting action. The 1767 N force at 0.9 MPa holds parts firmly, while the adjustable cushion reduces impact shock at the end of the clamp stroke.
Is the Airtac SC50 Standard Cylinder SC50X350SCB the Right Cylinder?
Choose the SC50X350SCB when your application needs a mid-range force of 982 N at standard plant air pressure and a pivoting rear mount. If you require more force, stepping up to the 63 mm bore (SC63 series) provides 1559 N at 0.5 MPa. For lower force needs, the 40 mm bore delivers 628 N.
At 350 mm stroke, side loads must be carefully managed to prevent rod bending. Always guide the load externally or use a guided cylinder if significant lateral forces are present. For direct replacement, match these five points: 50 mm bore, 350 mm stroke, PT port thread, CB rear double clevis mounting, and the -S magnet for sensor compatibility.
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 SC50X350SCB FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
It is a direct replacement for another AirTAC SC50 tie-rod cylinder with a 350 mm stroke, PT ports, CB rear double clevis mount, and a built-in magnet. Because the SC series is a tie-rod design and not an ISO 15552 profile, it is not dimensionally interchangeable with ISO 15552 cylinders.
