About the Airtac SC50 Standard Cylinder SC50X1150STC
The AirTAC SC50X1150STC 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 and a long 1150 mm stroke, it is built for applications requiring extended linear reach. The 20 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration, while the PT1/4 port ensures standard flow compatibility.
This model is factory-equipped with a built-in magnet (-S suffix) for direct mounting of CMSG, DMSG, or EMSG sensors, enabling precise position feedback without external brackets. The TC centre trunnion mount, supplied with the TCM1 bracket (F-SC50TC), allows the cylinder to pivot during operation, making it ideal for swinging or articulating loads. The total extended body length is approximately 1300 mm (150 mm body + 1150 mm stroke).

Where the Airtac SC50 Standard Cylinder SC50X1150STC Is Used
Long-Stroke Part Transfer
Moves components across wide gaps in packaging or assembly lines, with the trunnion mount absorbing misalignment during the transfer arc.
Automated Welding Fixtures
Positions welding torches or clamps with a long, controlled stroke. The magnet sensors confirm end-of-travel for robotic sequence control.
Grain Chute Diverter
Pivots a heavy diverter gate on agricultural equipment, using the centre trunnion to handle the swinging motion and the long stroke for full gate actuation.
Is the Airtac SC50 Standard Cylinder SC50X1150STC the Right Cylinder?
Select the SC50X1150STC when your application demands a 50 mm bore force class with a stroke just under the 1200 mm maximum standard limit for this bore. If you need higher force, stepping up to the 63 mm bore provides 1559 N at 0.5 MPa; for a more compact build, the 40 mm bore offers 628 N. At this stroke length, the unsupported rod is susceptible to bending under side loads—always use an external guide rail or rod-alignment coupler to protect the rod bearing and seals. For direct replacement, match the bore, stroke, PT port thread, centre trunnion (TC) mount, and the integrated magnet sensor option.
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 SC50X1150STC FAQ
At the standard 0.5 MPa operating pressure, 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 increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
For strokes exceeding 300 mm, side loads can cause rod deflection and premature bearing wear. It is critical to guide the load externally with a linear rail or rod, and ensure the load is aligned axially with the piston rod. The TC centre trunnion mount helps by allowing the cylinder body to self-align, but it does not support the rod against lateral forces.
