About the Airtac SC50 Standard Cylinder SC50X450SCA
The SC50X450SCA is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore, 20 mm diameter piston rod, and a 450 mm stroke, this model is well-suited for medium-force material handling and actuation tasks.
This configuration includes a built-in magnet (-S) for direct mounting of CMSG, DMSG, or EMSG sensors, and a rear single clevis mount (CA, part F-SC50CA) that allows the cylinder to pivot during operation. The standard PT1/4 port and 21 mm adjustable air cushion provide smooth deceleration, while the TPU seals maintain a reliable operating range of -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X450SCA Is Used
Part Diverter
The 450 mm stroke and rear clevis mount allow the cylinder to pivot, making it ideal for pushing products off a conveyor line at a divert station.
Clamp & Fixture Actuation
With 1374 N of force at 0.7 MPa and sensor-ready position feedback, it reliably powers heavy-duty welding or assembly jigs.
Bin Gate Operator
The pivoting action from the CA clevis and high push force effectively open and close slide gates on hoppers or agricultural storage bins.
Is the Airtac SC50 Standard Cylinder SC50X450SCA the Right Cylinder?
For applications needing slightly more force, consider stepping up to the 63 mm bore (1559 N at 0.5 MPa). If a lower force and lighter weight are acceptable, the 40 mm bore (628 N at 0.5 MPa) is a compact alternative. At a 450 mm stroke, the 20 mm rod is robust, but any significant side load should be managed with an external guide to prevent rod bearing wear and bending.
To ensure a correct replacement, match these five points: 50 mm bore, 450 mm stroke, PT port thread, the rear clevis (CA) mounting accessory, and the built-in magnet (-S). This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with one.
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 SC50X450SCA FAQ
At 0.7 MPa (7 bar), the theoretical push force is 1374 N. The maximum push force at the 0.9 MPa operating limit is 1767 N. The pull force on the return stroke is lower due to the 20 mm rod area.
No. The SC50X450SCA is a double-acting cylinder and will not hold its position when air pressure is exhausted or lost. The piston will drift. For load holding, you must add an external mechanical lock, a rod brake, or a pilot-operated check valve.
