About the Airtac SC50 Standard Cylinder SC50X250STC
The AirTAC SC50X250STC is a 50 mm bore, 250 mm stroke double-acting tie-rod cylinder equipped with a built-in magnet (-S) and a centre trunnion mount (TC). It delivers 982 N of push force and 825 N of pull force at 0.5 MPa, making it a capable mid-range actuator for pivoting applications.
This model uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion at each end (21 mm long) decelerates the piston smoothly, while the TC mount, supplied with the TCM1 bracket (F-SC50TC), allows the cylinder to swing as the load moves through an arc.

Where the Airtac SC50 Standard Cylinder SC50X250STC Is Used
Conveyor Diverter Gates
The trunnion mount allows the cylinder body to pivot as it actuates a diverter gate on a conveyor line, directing packages without binding the rod.
Clamping & Welding Fixtures
Provides 1767 N of clamping force at 0.9 MPa. The built-in magnet lets CMSG/DMSG sensors confirm clamp position before a robotic weld cycle starts.
Agricultural Equipment Linkages
Operates chute deflectors or hopper doors on farm machinery. The TPU seals handle dusty, damp environments from -20 to +70 °C.
Is the Airtac SC50 Standard Cylinder SC50X250STC the Right Cylinder?
Select the SC50 when your application needs roughly 982 N of push force at standard plant air pressure. If you require more force, stepping up to the 63 mm bore provides 1559 N at the same 0.5 MPa. For lighter, more compact needs, the 40 mm bore offers 628 N.
This 250 mm stroke is well within the 1200 mm maximum standard stroke for a 50 mm bore. The centre trunnion mount is ideal for pivoting loads. To replace an existing cylinder, match five points: 50 mm bore, 250 mm stroke, PT1/4 ports, centre trunnion (TC) mounting, and the presence of a magnet for sensors (-S).
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 SC50X250STC 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 increases to 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The '-S' suffix means a magnet is built into the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel's tie-rod slots to detect piston position.
