About the Airtac SC50 Standard Cylinder SC50X1175S
The SC50X1175S is a double-acting AirTAC SC tie-rod cylinder with a 50 mm bore and a non-standard 1175 mm stroke, factory-built with a magnet for barrel-mounted sensors. At 0.5 MPa it delivers 982 N pushing force, and at the maximum operating pressure of 0.9 MPa the thrust rises to 1767 N, making it a capable mid-range actuator for long linear moves.
The 20 mm diameter piston rod features an M16x1.5 male thread and the cylinder body length A is 150 mm. The total extended length is approximately 1325 mm. Because the stroke exceeds the standard maximum of 1200 mm for bore 50, this unit is a made-to-order item. The adjustable air cushion (21 mm) helps decelerate the end-of-stroke mass smoothly.

Where the Airtac SC50 Standard Cylinder SC50X1175S Is Used
Long-Stroke Material Transfer
Pushes or pulls bins, pallets, or components across a 1175 mm span on roller conveyors. The built-in magnet allows end-of-stroke sensing with CMSG/DMSG sensors to sequence the next operation.
Automated Gantry Tooling
Moves a lightweight welding torch, glue dispenser, or marking head along one axis. The 20 mm rod is rigid enough for axial loads, but an external guide rail is recommended for cantilevered tooling.
Vertical Lift Gate Actuation
Operates a tall sliding gate or hopper door requiring a long, straight stroke. The adjustable cushion softens the stop at both ends, reducing wear on the gate linkage.
Is the Airtac SC50 Standard Cylinder SC50X1175S the Right Cylinder?
Choose the SC50 when the 0.5 MPa push force of 982 N fits the load; if you need more force, the SC63 bore delivers 1559 N at the same pressure. For lighter, faster applications the SC40 provides 628 N. This 1175 mm stroke is non-standard and requires careful side-load management—long unsupported rods are prone to bending under lateral force. Use an external linear guide or a guided cylinder if the load is not perfectly axial.
To replace an existing cylinder, match five points: 50 mm bore, 1175 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic (no bracket) mounting. The SC is a tie-rod design, shorter than an ISO 15552 cylinder, so it is not dimensionally interchangeable with ISO 15552 profiles.
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 SC50X1175S 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 the push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf (1961 N), but the recommended operating range is 0.15–1.0 MPa.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder. Mounting accessories and overall dimensions are not interchangeable. Use only AirTAC SC-specific mounting brackets (e.g., FA, LB, TC) designed for the 50 mm bore.
