About the Airtac SC50 Standard Cylinder SC50X1150S
The SC50X1150S is a double-acting pneumatic cylinder delivering 982 N push force at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and a long 1150 mm stroke, it features a 20 mm diameter piston rod and an adjustable air cushion (21 mm length) to decelerate the load smoothly at end-of-travel.
This model includes the factory-installed -S magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the tie-rod barrel for non-contact position sensing. The body length A is 150 mm, giving a total extended length of approximately 1300 mm. It uses a PT1/4 port and an M16x1.5 rod thread, with standard TPU seals rated for -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X1150S Is Used
Long-Reach Material Transfer
The 1150 mm stroke and 50 mm bore provide the reach and force to push or pull products across wide conveyor gaps or transfer stations, with sensor feedback for precise end-of-stroke confirmation.
Automated Panel Indexing
Ideal for indexing large panels or doors in woodworking and metal fabrication lines, where the adjustable cushion protects the workpiece from impact damage at the end of the long travel.
Vertical Lift Assistance
Used in low-speed vertical lift assists for ergonomic workstations, the 1767 N maximum force at 0.9 MPa can handle moderate loads, while the magnet enables mid-stroke deceleration sensing.
Is the Airtac SC50 Standard Cylinder SC50X1150S the Right Cylinder?
For applications requiring slightly less force, the 40 mm bore SC40 series provides 879 N at 0.7 MPa. If higher force is needed, stepping up to the 63 mm bore delivers 2182 N at the same pressure. At a stroke of 1150 mm, the unsupported piston rod is susceptible to bending under side loads; an external linear guide or a guided cylinder configuration is strongly recommended to protect the rod bearing and ensure reliable operation.
When replacing an existing cylinder, match five key points: 50 mm bore, 1150 mm stroke, PT1/4 port thread, the built-in magnet (-S) for sensor compatibility, and the basic (no bracket) mounting style. This is a tie-rod cylinder 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 SC50X1150S FAQ
At the standard 0.7 MPa operating pressure, the push force is 1374 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. These values are theoretical and do not account for friction or dynamic losses.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 cylinder. It is not dimensionally interchangeable. Replacements should match another AirTAC SC tie-rod cylinder with the same 50 mm bore, 1150 mm stroke, PT1/4 port, and built-in magnet.
