About the Airtac SC50 Standard Cylinder SC50X850STC
The AirTAC SC50X850STC 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 an 850 mm stroke and a 20 mm diameter piston rod, this model is well-suited for medium-reach linear tasks in material handling and automation where consistent air-powered thrust is required.
This configuration includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for precise, non-contact position feedback. The TC centre trunnion mount, supplied with the TCM1 bracket, enables the cylinder to pivot, accommodating swinging loads and angular motion during extension and retraction.

Where the Airtac SC50 Standard Cylinder SC50X850STC Is Used
Conveyor Diverting
The 850 mm stroke and pivoting TC mount make this cylinder ideal for long-reach diverters or gates on conveyor lines, where the cylinder body must swing to follow the gate's arc.
Welding Fixture Clamping
Delivers 1767 N of clamping force at 0.9 MPa. The built-in magnet provides sensor confirmation of the clamp's open/closed state in automated welding cells.
Agricultural Machinery Actuation
Used for remote actuation of chutes or levers on farm equipment. The TPU seals and robust tie-rod design handle outdoor temperature swings from -20 to +70 °C.
Is the Airtac SC50 Standard Cylinder SC50X850STC the Right Cylinder?
The SC50 bore provides 982 N of force at 0.5 MPa, filling a mid-range capability between the smaller SC40 (628 N) and the larger SC63 (1559 N). For an 850 mm stroke, ensure the rod is adequately supported against side loads; long, unsupported strokes can subject the 20 mm rod to bending moments. Consider an external guide or a guided cylinder if the load is not perfectly axial. When replacing this unit, match the 50 mm bore, 850 mm stroke, PT port thread, TC centre trunnion mounting (F-SC50TC), 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 SC50X850STC 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.
Yes, the TC centre trunnion mount code means the cylinder is supplied with the TCM1 trunnion bracket. The complete accessory part code for this assembly is F-SC50TC.
