About the Airtac SC80 Standard Cylinder SC80X350STC
The SC80X350STC is an 80 mm bore, 350 mm stroke double-acting pneumatic cylinder delivering 2513 N push force at 0.5 MPa (4523 N at 0.9 MPa). It features a 25 mm diameter piston rod, PT3/8 port connections, and a 28 mm adjustable air cushion at each end to decelerate the piston smoothly.
This model is factory-configured with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (TC) complete with the TCM1 bracket (F-SC80TC) for pivoting applications. The standard TPU seals provide reliable operation from -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X350STC Is Used
Material Handling Gates
The 350 mm stroke and centre trunnion mount allow this cylinder to pivot and actuate diverter gates on conveyor systems, handling medium-weight packages with the 2513 N push force at standard line pressure.
Clamping & Fixturing
With 4523 N of force at 0.9 MPa and magnetic piston sensing, this cylinder provides strong, verifiable clamping for welding fixtures and assembly jigs, confirming jaw position before a cycle starts.
Agricultural Equipment Actuation
The trunnion-mounted SC80X350STC is suited for pivoting linkages on farm machinery like chute controls or bale handlers, where the 25 mm rod and robust tie-rod construction withstand dirty, demanding environments.
Is the Airtac SC80 Standard Cylinder SC80X350STC the Right Cylinder?
Choose the SC80 when your application requires between 2513 N and 4523 N of push force. For higher force in the same bore family, step up to the SC100 which provides 3927 N at 0.5 MPa. The 350 mm stroke is within the 1500 mm maximum standard stroke for this bore. For strokes over 300 mm, ensure side loads are managed—long unsupported rods can bend under lateral force; consider an external guide or a guided cylinder if the load is not purely axial.
For a direct replacement, match five key points: 80 mm bore, 350 mm stroke, PT3/8 port thread, centre trunnion (TC) mounting with TCM1 bracket, and the built-in magnet (-S) 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 SC80 Standard Cylinder SC80X350STC FAQ
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
Yes. The -S suffix indicates a built-in magnet on the piston, allowing you to clamp AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the cylinder barrel to detect piston position without additional brackets.
