About the Airtac SC80 Standard Cylinder SC80X850TC
The AirTAC SC80X850TC is a double-acting single-rod pneumatic cylinder delivering 2513 N of push force at 0.5 MPa (up to 4523 N at 0.9 MPa). With an 80 mm bore and an 850 mm stroke, it is built for medium-to-long linear movements where the load needs to pivot during operation.
The cylinder body length A is 182 mm, giving a total extended length of approximately 1032 mm. It features a 25 mm diameter piston rod with an M20x1.5 male thread, a 28 mm adjustable air cushion, and a PT3/8 port. The TC suffix denotes the centre trunnion mount, supplied with the TCM1 bracket (F-SC80TC), allowing the cylinder to swing as it actuates.

Where the Airtac SC80 Standard Cylinder SC80X850TC Is Used
Pivoting Conveyor Gates
The centre trunnion mount lets the cylinder swing freely, making it ideal for actuating diverter gates or sorting flaps on conveyor lines where the cylinder body must pivot.
Clamp & Weld Fixtures
Delivers 2513 N of clamping force at standard shop air, suitable for holding workpieces in welding or assembly fixtures that require the cylinder to rotate into position.
Agricultural Equipment Actuation
Used on harvesters or spreaders to control chute direction or hopper doors, where the trunnion mount accommodates the arcing motion of the linkage.
Is the Airtac SC80 Standard Cylinder SC80X850TC the Right Cylinder?
For a step up in force, the SC100 bore provides 3927 N at 0.5 MPa; for a lighter, more compact solution, the SC63 bore delivers 1559 N. At 850 mm stroke, the 25 mm rod is long and unsupported side loads can cause rod bending or premature bearing wear—always guide the load externally or use a guided cylinder if lateral forces are present.
This model is a direct replacement only for another AirTAC SC80 tie-rod cylinder with an 850 mm stroke, PT3/8 ports, centre trunnion (TC) mounting, and no magnet. Always match bore, stroke, port thread, mounting accessory, and magnet option to ensure correct fit and function.
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 SC80 Standard Cylinder SC80X850TC FAQ
At 0.5 MPa the push force is 2513 N and pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The SC80X850TC is a double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centered. For load holding without live pressure, add a pilot-operated check valve or an external rod brake.
