About the Airtac SC50 Standard Cylinder SC50X160CB
The SC50X160CB is a 50 mm bore, 160 mm stroke double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (up to 1767 N at 0.9 MPa). This tie-rod design uses a 20 mm diameter piston rod with M16x1.5 male threads and features an adjustable air cushion of 21 mm at each end to decelerate the piston smoothly.
This model is configured with a rear double clevis (CB) mounting, part F-SC50CB, allowing the cylinder body to pivot during operation for articulated motion. The standard PT1/4 ports and TPU seals provide reliable performance in normal industrial environments from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X160CB Is Used
Agricultural Machinery
The rear double clevis mount allows the cylinder to pivot as it actuates, making it ideal for lifting and tilting mechanisms on harvesters, spreaders, and tillage equipment where the load path changes angle.
Conveyor Diverters
With 982 N of push force at standard shop air, this cylinder reliably shifts diverter gates and sorting paddles on material handling lines. The 160 mm stroke provides ample travel for wide belt applications.
Clamping Fixtures
The 50 mm bore delivers strong, consistent clamping force for welding jigs and assembly fixtures. The adjustable cushion protects the fixture from impact shock, extending tooling life in high-cycle production.
Is the Airtac SC50 Standard Cylinder SC50X160CB the Right Cylinder?
For applications needing more force, stepping up to the 63 mm bore provides 1559 N of push force at 0.5 MPa. If a non-pivoting mount is preferred, the basic or LB foot-mounted SC50 variants simplify installation. The 160 mm stroke is well within the 1200 mm maximum standard stroke for this bore, so no special stroke considerations apply.
To replace an existing cylinder, match five key points: 50 mm bore, 160 mm stroke, PT port thread, CB rear double clevis mounting, and confirm whether a magnet is needed (this model has no built-in magnet). The SC is a tie-rod cylinder and is dimensionally shorter than an ISO 15552 profile cylinder; it is not a drop-in ISO 15552 replacement.
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 SC50X160CB 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, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf. All forces assume a clean, filtered air supply at the specified pressure.
No. The SC50X160CB is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is lost or the directional valve is centered, the piston will drift or drop under load. For load-holding, you must add a pilot-operated check valve or an external mechanical rod lock.
