About the Airtac SC80 Standard Cylinder SC80X905STC
The SC80X905STC is an 80 mm bore double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa. With a 905 mm stroke, this model is suited for long linear movements in material handling or process automation where a centre pivot mount is required.
This configuration includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, and a centre trunnion mount (-TC suffix) supplied with the TCM1 bracket for pivoting applications. The 25 mm diameter piston rod and 28 mm adjustable air cushion at each end provide smooth deceleration, while the PT1/4 port thread ensures straightforward pneumatic connection.

Where the Airtac SC80 Standard Cylinder SC80X905STC Is Used
Long-Stroke Part Transfer
The 905 mm stroke and 2513 N push force move heavy pallets or components between distant conveyor stations, with trunnion mounting allowing the cylinder body to pivot as it cycles.
Automated Welding Fixture Clamping
Centre trunnion mount suits pivoting clamp arms in welding jigs. The built-in magnet enables end-of-stroke confirmation via CMSG sensors to interlock with the robot controller.
Diverter Gate Actuation
Operates a diverter gate on a gravity roller conveyor, using the 28 mm cushion to softly stop the gate at each end of travel, reducing impact and noise in high-cycle sorting systems.
Is the Airtac SC80 Standard Cylinder SC80X905STC the Right Cylinder?
For applications requiring slightly less force, the 63 mm bore SC63 series provides 1559 N at 0.5 MPa. If higher force is needed, stepping up to the 100 mm bore SC100 series offers 3927 N at the same pressure. Always match bore, stroke, port thread, mounting accessory, and magnet option when replacing an existing cylinder.
At a 905 mm stroke, the rod is fully supported only at the bearing and piston, making it susceptible to bending under side loads. For this stroke length, consider an external guide rail or a guided cylinder if the load is not perfectly axial, to prevent premature rod bearing wear and seal failure.
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 SC80X905STC 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, push force reaches 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
Match five key points: 80 mm bore, 905 mm stroke, PT1/4 port thread, centre trunnion (TC) mount with TCM1 bracket, and the built-in magnet (-S) for sensors. This is a tie-rod cylinder, not an ISO 15552 profile, so verify the shorter body length (A=182 mm) and mounting dimensions against your existing unit.
