About the Airtac SC50 Standard Cylinder SC50X1160STC
The AirTAC SC50X1160STC is a double-acting single-rod 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 1160 mm stroke, this model is built for linear applications requiring extended reach, such as material transfer or vertical lifting within its force class.
This configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and the centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC50TC), allowing the cylinder to pivot during operation. The 20 mm diameter rod and 21 mm adjustable air cushion at each end ensure smooth deceleration, while the PT1/4 ports and M16x1.5 rod thread maintain standard AirTAC connectivity.

Where the Airtac SC50 Standard Cylinder SC50X1160STC Is Used
Long-Reach Material Transfer
Pushes or pulls components across an 1160 mm span on conveyors or linear transfer lines, with trunnion mounting absorbing any minor misalignment during the stroke.
Pivoting Clamp or Fixture
The TC mount allows the entire cylinder body to swing, making it suitable for clamping mechanisms that must retract clear of the workpiece, with sensor confirmation at stroke ends.
Vertical Lift Assist
Provides 1767 N of push force for lifting or lowering loads up to 1160 mm, with the trunnion pivot handling the natural arc of a lift arm linkage.
Is the Airtac SC50 Standard Cylinder SC50X1160STC the Right Cylinder?
Select the SC50X1160STC when your application needs a 50 mm bore with a stroke close to the maximum standard limit of 1200 mm and a pivoting mount. The centre trunnion is ideal for swinging loads, reducing rod bending stress compared to a fixed mount. For higher force, step up to the 63 mm bore (1559 N at 0.5 MPa); for a shorter, more compact solution, the 40 mm bore offers 628 N. At this stroke length, ensure the rod is guided externally if any side load is present, as an unsupported 1160 mm stroke on a 20 mm rod is susceptible to bending and bearing wear. For a direct replacement, match the 50 mm bore, 1160 mm stroke, PT port thread, centre trunnion mount, and the integrated magnet for sensor compatibility.
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 SC50X1160STC FAQ
At the standard 0.5 MPa operating pressure, the cylinder pushes with 982 N and pulls with 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, but the recommended operating range is 0.15–1.0 MPa.
Match five key specifications: the 50 mm bore, the 1160 mm stroke, the PT1/4 port thread, the centre trunnion (TC) mounting style with the TCM1 bracket, and the built-in magnet (-S) for sensor mounting. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC series cylinder with the same configuration.
