About the Airtac SC50 Standard Cylinder SC50X325CB
The AirTAC SC50X325CB is a double-acting tie-rod cylinder with a 50 mm bore and 325 mm stroke, equipped with a rear double clevis (CB) mount for pivoting applications. At 0.5 MPa it produces 982 N of push force and 825 N on the pull stroke, while at the maximum operating pressure of 0.9 MPa the push thrust reaches 1767 N, driven by a 20 mm diameter piston rod.
The CB mounting style uses a fork/double lug at the cap end (accessory F-SC50CB), allowing the entire cylinder body to pivot during actuation. With a body length A of 150 mm and a 21 mm adjustable air cushion at each end, this model decelerates the piston smoothly and fits into compact articulated mechanisms where the load path changes angle.

Where the Airtac SC50 Standard Cylinder SC50X325CB Is Used
Dump Trailer Gate Actuation
The rear clevis mount lets the cylinder pivot as it opens and closes a hopper or trailer gate, handling the 982 N push force needed to move bulk material loads.
Clamp & Fixture Pivoting Arms
Operates a pivoting clamp arm on a welding or assembly fixture. The CB mount absorbs the arc motion, while the adjustable cushion reduces impact at the end of the 325 mm stroke.
Sorting Gate Diverter
Pushes a diverter gate on a conveyor line. The double clevis allows the cylinder to swing freely as the gate moves between product lanes, with consistent force at line-pressure air.
Is the Airtac SC50 Standard Cylinder SC50X325CB the Right Cylinder?
Choose the SC50X325CB when your application needs a pivoting mount and around 1000 N of force at standard shop air. If you require higher force, stepping up to the 63 mm bore (SC63 series) provides 1559 N push at 0.5 MPa; for a lighter, more compact solution the 40 mm bore delivers 628 N. This 325 mm stroke is within the 1200 mm maximum standard stroke for the 50 mm bore.
For strokes of 300 mm or more, avoid side loading the rod—external guide rails or a guided cylinder should be used to prevent rod bending and premature bearing wear. When replacing an existing unit, match five points exactly: 50 mm bore, 325 mm stroke, PT port thread, CB rear double clevis mounting, and confirm whether a magnet (-S) is required for sensors.
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 SC50X325CB FAQ
At 0.7 MPa supply pressure the SC50 bore produces 1374 N of push force and 1155 N of pull force (calculated from the 825 N pull at 0.5 MPa). The maximum operating push force at 0.9 MPa is 1767 N.
Yes. The SC50X325CB comes with the CB rear double clevis (F-SC50CB), but the cylinder body is compatible with all SC50 mounting accessories—including LB foot, FA/FB flanges, CA single clevis, or TC centre trunnion. The clevis is bolted to the tie-rod end, so it can be swapped if your pivot geometry changes.
