About the Airtac SC50 Standard Cylinder SC50X1450S
The AirTAC SC50X1450S is a double-acting single-rod pneumatic cylinder with a 50 mm bore and an extended 1450 mm stroke. At the standard 0.7 MPa operating pressure, this model delivers 1374 N of push force, making it suitable for long-reach material transfer or pusher applications where a compact bore must cover a significant distance.
This non-standard stroke cylinder includes a built-in magnet (suffix -S), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the barrel for precise position feedback. The piston rod is 20 mm in diameter with an M16x1.5 male thread, and the adjustable air cushion at each end (21 mm long) decelerates the piston to reduce end-of-stroke impact. The body length A is 150 mm, giving a total extended length of approximately 1600 mm.

Where the Airtac SC50 Standard Cylinder SC50X1450S Is Used
Long-Stroke Part Transfer
The 1450 mm stroke moves components between distant conveyor stations or assembly nests, with the built-in magnet enabling mid-stroke and end-of-stroke sensor confirmation.
Automated Pusher Systems
Delivers 1767 N of push force at 0.9 MPa to advance heavy trays or pallets along a roller line, where the adjustable cushion protects the mechanism at full extension.
Vertical Gate Actuation
Operates a tall hopper gate or diverter door, using the 20 mm rod and PT 1/4 ports for consistent, repeatable motion over the long travel distance.
Is the Airtac SC50 Standard Cylinder SC50X1450S the Right Cylinder?
For a 50 mm bore at 1450 mm stroke, confirm that the rod's unsupported length is managed—at this extension, side loads can cause rod bending or bearing wear; an external guide or a guided cylinder is strongly recommended. If the 50 mm bore's 0.5 MPa push force of 982 N is marginal, stepping up to a 63 mm bore (1559 N at 0.5 MPa) provides a substantial force increase without a large footprint jump.
To ensure a correct replacement, match five key points: bore (50 mm), stroke (1450 mm), port thread (PT 1/4), mounting accessory (basic, no bracket), and the built-in magnet (-S) for sensor compatibility. This SC 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 SC50X1450S FAQ
At 0.5 MPa, the cylinder produces 982 N pushing and 825 N pulling. 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.
The maximum standard stroke for a 50 mm bore SC cylinder is 1200 mm, so 1450 mm is a non-standard, made-to-order length. For any stroke over 300 mm, especially at this length, side loading must be avoided. Use an external linear guide or a guided cylinder to support the rod and prevent bending or uneven seal wear.
