About the Airtac SC50 Standard Cylinder SC50X275CB
The SC50X275CB is a 50 mm bore, 275 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series, fitted with a rear double clevis (CB) mount for pivoting applications. At 0.5 MPa it generates 982 N of push force and 825 N of pull force, rising to a maximum operating thrust of 1767 N at 0.9 MPa, driven by a 20 mm diameter piston rod with M16x1.5 male threads.
This model uses PT1/4 port threads and the standard TPU/NBR seal package rated for -20 to +70 °C. The adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly, while the 150 mm body length A plus the 275 mm stroke gives a compact extended envelope. The CB clevis (part F-SC50CB) allows the cylinder to swing through an arc, making it suitable for linkages and dump mechanisms.

Where the Airtac SC50 Standard Cylinder SC50X275CB Is Used
Dump Trailer Gate Actuation
The rear double clevis mount lets the cylinder pivot as it extends, ideal for opening and closing tailgates or chutes on agricultural trailers where the 275 mm stroke provides sufficient travel.
Clamping & Fixturing
Delivers 1767 N of clamping force at 0.9 MPa. The CB mount allows the cylinder body to align with the linkage as the clamp engages, reducing side stress on the rod.
Diverter Gate Operation
Used on conveyor lines to swing a diverter plate. The adjustable cushion absorbs the impact at the end of the 275 mm stroke, preventing shock loads from reaching the mounting structure.
Is the Airtac SC50 Standard Cylinder SC50X275CB the Right Cylinder?
Choose the SC50X275CB when your application needs a mid-range force actuator that can pivot at the rear. If the 982 N push force at 0.5 MPa is marginal, stepping up to the 63 mm bore (SC63 series) provides 1559 N at the same pressure. For strokes of 275 mm and above, ensure the rod is not exposed to significant side load—an external guide rail or a guided cylinder should be used to protect the rod bearing and seals from bending stress.
For a direct replacement, match five points: 50 mm bore, 275 mm stroke, PT1/4 ports, the CB rear double clevis mounting, and the standard non-magnetic piston. The SC tie-rod design is shorter than an ISO 15552 cylinder, so it is not dimensionally interchangeable with ISO 15552 profile types.
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 SC50X275CB FAQ
At the standard operating pressure of 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.
No. The SC50X275CB is a double-acting cylinder and will not hold its position if air pressure is exhausted or the directional valve is centered. The piston will drift or drop under load. If load holding is required, you must add a pilot-operated check valve or an external mechanical rod lock.
