About the Airtac SC50 Standard Cylinder SC50X350CB
The SC50X350CB is a 50 mm bore double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). With a 350 mm stroke and a 20 mm diameter piston rod, this model suits medium-reach clamping, pressing, and material-handling tasks where the cylinder needs to pivot during operation.
This variant includes a CB rear double clevis (fork) mounting, part F-SC50CB, which allows the cylinder body to swing in a single plane. The adjustable air cushion (21 mm) softens end-of-stroke impact, protecting the tie-rod assembly. Ports are PT1/4, and the standard TPU seals provide reliable service from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X350CB Is Used
Pivoting Gate Actuator
The CB rear clevis allows the SC50X350CB to pivot smoothly, making it ideal for opening and closing chutes or gates on agricultural processing equipment where a 350 mm stroke is needed.
Conveyor Diverter Arm
With 982 N of push force, this cylinder can reliably swing a diverter arm on a packaging conveyor, directing products between lanes with a controlled, cushioned motion.
Clamp & Weld Fixture
The 350 mm stroke provides ample reach for a pivoting clamp arm in a welding fixture. The adjustable cushion decelerates the clamp gently, preventing part damage.
Is the Airtac SC50 Standard Cylinder SC50X350CB the Right Cylinder?
For applications requiring more force, stepping up to the 63 mm bore provides 1559 N at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the 40 mm bore offers 628 N. At 350 mm stroke, the 20 mm rod is robust, but if the load applies significant side force, an external linear guide or a guided cylinder is recommended to prevent rod bending and premature bearing wear.
To ensure a correct replacement, match five key points: 50 mm bore, 350 mm stroke, PT1/4 port thread, the CB rear double clevis mounting accessory, and the absence of a built-in magnet. 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 SC50X350CB 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 increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The SC50X350CB is a double-acting cylinder and will not hold its position when air pressure is exhausted or lost. The piston can drift or drop. If load holding is required, you must add an external rod lock, a pilot-operated check valve, or a mechanical brake.
